Synchronics Electronics specializes in repairing and refurbishing Entrelec terminal blocks, connector assemblies, relay modules, and connectivity systems used in industrial control panels and switchboards. With 30 years of experience servicing critical infrastructure across Indian manufacturing, we understand the harsh operating environments where Entrelec components fail — high-vibration factories, dusty cement plants, moisture-prone textile mills, and temperature-extreme foundries. Our technicians restore Entrelec connectivity solutions to factory specifications, reducing costly production downtime for Indian OEMs and system integrators.
Expert repair of Entrelec terminal blocks, connectors and industrial connectivity components.
ENTRELEC Product Lines We Repair
Our engineers are trained on the full ENTRELEC product range. Below are the major product families we service.
Entrelec Terminal Block Systems
Modular rail-mounted terminal blocks for power distribution and signal connectivity. Common failures include corroded contacts, loose wire terminations, thermal burnout under overload, and moisture ingress in humid environments. Industrial plants often face intermittent connection losses due to oxidation or vibration-induced wire slippage.
Entrelec Connector Assemblies
Pre-assembled connector harnesses and multi-pin connectors for panel-to-field wiring. Failures occur due to contact corrosion in salt-fog environments, pin misalignment after repeated mating cycles, and dielectric breakdown under high voltage stress in switching applications.
Entrelec Safety Relay Terminals
Specialized terminal blocks for safety-rated control circuits in machinery and emergency stop systems. Faults include electrical erosion of safety-rated contacts, coil burnout in voltage-transient events, and mechanical jamming of safety interlocks in high-vibration press shops.
Entrelec DIN Rail Accessories
Support rails, clip assemblies, and mechanical mounting hardware. Failures involve corrosion of DIN rail under humidity, loose clip retention causing terminal block migration, and mechanical deformation after thermal cycling in furnace control applications.
Entrelec Power Distribution Blocks
High-current distribution terminals for main switchboards and UPS integration. Common issues include thermal stress at solder joints, contact resistance rise under sustained load, and spring-clip fatigue leading to loose connections in cement and steel plants.

Common ENTRELEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ENTRELEC equipment arriving at our workshop.
- ✓Corroded terminal contacts causing intermittent circuit loss — Entrelec terminal blocks exposed to humidity, salt air, or chemical fumes in Indian coastal or chemical process facilities oxidize internally. Copper contacts develop white or green oxide films, increasing contact resistance and triggering random disconnections during critical production runs.
- ✓Loose wire terminations and intermittent connections — Vibration in textile looms, printing presses, and injection molding machines causes wires to gradually shift within Entrelec terminal blocks. Repeated thermal cycling in foundries and heat-treat shops also loosens screw-down wire clamps, creating dangerous arcing and nuisance trips.
- ✓Thermal burnout and blackening of terminal blocks under overload — Undersized Entrelec terminal blocks installed in high-current applications — common in Indian steel mills and heavy machinery installations — exceed current ratings during fault conditions or soft-start inrush. The insulating material chars, solder joints crack, and contacts weld or fracture under arc heat.
- ✓Pin misalignment and contact separation in connector assemblies — Repeated mating and unmating cycles in modular Entrelec connector systems cause contact-pin wear and spring fatigue. Mechanical stress during panel rework, combined with impact vibration in transport and manufacturing floors, leads to broken or bent pins and loose contact retention.
- ✓Moisture ingress and dielectric breakdown in sealed terminal blocks — Entrelec sealed terminal blocks in textiles, food processing, and wet chemical plants face condensation and direct water spray. Moisture breaches the sealing gaskets, deposits salt and minerals on insulating surfaces, and causes creepage and tracking — arcing pathways that lead to phase-to-ground faults and equipment shutdowns.
- ✓Spring-clip fatigue and loss of terminal retention — In high-temperature furnace control and continuous-process applications across Indian foundries and chemical plants, Entrelec spring clips undergo thermal cycling that reduces metal fatigue strength. Clips lose their grip on terminal blocks, causing blocks to migrate on DIN rails and creating open circuits.

Frequently Asked Questions — ENTRELEC Repairs
Do you repair Entrelec equipment anywhere in India?+
Yes. Synchronics repairs the full Entrelec product range — terminal blocks, connector assemblies, relay terminals, DIN rail systems, and power distribution blocks. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Lucknow, and all other major cities, with centralized repair at our ISO 9001 certified facility in Vadodara, Gujarat. Turnaround is typically 7-10 working days.
What causes Entrelec terminal blocks to fail in Indian textile mills and printing presses?+
High-frequency vibration from looms and rotating presses causes wires to loosen inside Entrelec terminal blocks, creating intermittent open circuits. Moisture and lint accumulation corrode contacts. Temperature swings from air conditioning changes induce thermal stress on solder joints. Synchronics addresses all three failure modes — we re-secure terminations, clean and protect contacts, and inspect solder integrity before return to critical control circuits.
Can you replace individual contacts or pins in Entrelec connectors, or must we buy a new assembly?+
We can replace individual damaged pins and contacts in most Entrelec connector series, which is far more cost-effective than purchasing new assemblies. Our technicians desolder failed pins, install new Entrelec-specification pins with correct contact force, and re-solder under controlled conditions. This saves 60-70 percent of the cost of a new connector while maintaining factory performance and reliability.
How do you prevent corroded Entrelec terminal blocks from failing again in coastal or humid facilities?+
After cleaning and restoring Entrelec terminal blocks, we apply a thin protective coating of lacquer or silicone conformal sealant to exposed copper contacts. We also recommend upgrading to Entrelec IP67 sealed or stainless-steel contact options if blocks are in spray zones. Synchronics provides environmental recommendations and component upgrade analysis as part of the repair report.
Do you stock genuine Entrelec spare parts, or do you use aftermarket replacements?+
We use only genuine Entrelec spare parts, springs, clips, gaskets, and contact pins for all repairs. We maintain a curated inventory of common Entrelec replacement components to minimize repair turnaround. For obsolete or long-lead Entrelec items, we source through authorized Entrelec distributors across India and Europe. All parts are certified original before installation.
How do I send my ENTRELEC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ENTRELEC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on ENTRELEC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your ENTRELEC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
