ETA ELECTRIC Equipment We Repair — By Category
ETA ELECTRIC Product Lines We Repair
Our engineers are trained on the full ETA ELECTRIC product range. Below are the major product families we service.
Thermal Overload Relays (TR Class)
ETA ELECTRIC thermal overload relays provide motor and circuit protection via bimetallic or electronic thermal compensation. Common repair issues include contact welding, thermal element degradation, and calibration drift due to thermal cycling in high-ambient Indian manufacturing environments.
Solid-State Motor Controllers (EMS-Logic)
Modular solid-state controllers for three-phase motor protection and soft-start functionality. Failures often stem from thyristor degradation, gate drive circuit faults, and heat sink thermal management issues in tropical climates across India.
Miniature Circuit Breakers (MCB Standard)
Compact DIN-rail mounted breakers for distribution and branch circuit protection. Typical faults include thermal bimetal fatigue, mechanical trip mechanism wear, and magnetic coil failures from voltage surges common in Indian power systems.
Electronic Timer Modules (ET Series)
Plug-in timing relay modules with delay-on-make and delay-on-break functionality. Common failures include capacitor aging, microcontroller resets under power supply noise, and relay contact oxidation in humid industrial environments.
Terminal Blocks and Modular Connectors (TBE Range)
High-current industrial terminal blocks and push-in connectors. Issues include corrosion of copper contacts due to salt spray exposure in coastal Indian facilities, loose crimped connections, and insulation degradation.
Contactor Units (CT and CTM Series)
Electromagnetically-operated contactors for motor switching and load control. Repair typically addresses contact surface pitting, coil insulation breakdown, mechanical armature stiction, and spring fatigue from cycling stress.

Common ETA ELECTRIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ETA ELECTRIC equipment arriving at our workshop.
- ✓Thermal element open circuit or calibration drift — ETA ELECTRIC bimetallic thermal elements degrade over 8-12 years due to repeated thermal cycling in Indian foundries, textile dyers, and heat-treatment plants. Thermal hysteresis increases, causing nuisance trips or failure to trip at rated current.
- ✓Solid-state controller thyristor failure or gate drive loss — ETA ELECTRIC EMS-Logic controllers operate in high-temperature machine tool rooms and foundries where ambient heat, dust accumulation, and inadequate heat sink cooling degrade thyristor junctions and isolate gate driver circuits. Voltage transients from VFD interference also cause gate oxide breakdown.
- ✓Contactor armature stiction or contact welding — ETA ELECTRIC contactors in Indian power systems experience contact welding during inrush surges from undersized panels or soft-starters. Armature stiction occurs when dust, rust, or salt spray deposits accumulate on the pole pieces in coastal or damp mill environments.
- ✓MCB thermal bimetal fatigue or magnetic coil burn-out — ETA ELECTRIC MCBs exposed to chronic overload currents (110-130% of rating) in Indian power distribution systems experience bimetal metal fatigue and stress relaxation. Magnetic coils burn out when short-circuit levels exceed breaker interruption rating due to undersized panels.
- ✓Electronic timer module microcontroller reset or relay chatter — ETA ELECTRIC ET-series timers fail due to unstable power supplies, voltage sag events, and high-frequency noise from nearby VFDs and soft-starters common in Indian textile mills and food processing plants. Relay contacts chatter when reset occurs mid-cycle.
- ✓Terminal block contact corrosion or loose crimped connections — ETA ELECTRIC TBE terminal blocks in coastal facilities (Mumbai, Chennai ports) and salt-spray environments suffer accelerated corrosion of copper contacts. Loose crimp connections result from vibration-induced cold flow of aluminum ferrules on stranded wire.

Frequently Asked Questions — ETA ELECTRIC Repairs
Do you repair ETA ELECTRIC equipment anywhere in India?+
Yes. Synchronics repairs the full ETA ELECTRIC product range — thermal relays, contactors, solid-state controllers, MCBs, timer modules, and terminal blocks. We offer PAN India door-to-door pickup and delivery from all major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and Kolkata. All repairs are completed at our ISO-certified facility in Vadodara, Gujarat, with full diagnostic testing and calibration.
What is the typical turnaround time for ETA ELECTRIC relay and contactor repairs?+
Standard repair turnaround for ETA ELECTRIC thermal relays, contactors, and timer modules is 5-7 working days. For urgent breakdowns, we offer express diagnostics and same-day spare part availability at premium rates. Complex solid-state controller repairs may take 10-14 days due to testing protocols. We provide daily status updates and courier the repaired equipment with full test certificates and OEM-equivalent spare parts.
Do you stock genuine ETA ELECTRIC spare parts and offer warranty on repairs?+
Yes. Synchronics maintains inventory of genuine ETA ELECTRIC thermal elements, contact stacks, coil assemblies, and solid-state modules. All repairs come with 12-month warranty against material and workmanship defects. We also provide extended 24-month warranty on solid-state controller repairs. Spare parts are sourced directly from authorized ETA ELECTRIC distributors to ensure authenticity and OEM compliance.
What causes ETA ELECTRIC thermal relay nuisance trips in Indian textile mills?+
Thermal relay nuisance trips typically occur due to calibration drift from thermal cycling in dye-house and heat-treatment environments where ambient temperatures exceed 45 degrees Celsius. Additionally, under-sized cable runs and improper relay selection (undersized rating) cause chronic overload currents that degrade bimetallic elements. Synchronics performs thermal element replacement, full recalibration per IEC standards, and load analysis to ensure proper relay selection for your application.
Can Synchronics repair ETA ELECTRIC solid-state controllers damaged by VFD interference?+
Yes. ETA ELECTRIC EMS-Logic and solid-state controllers often suffer thyristor and gate-drive failures when installed near VFDs without proper shielding and grounding. Synchronics replaces power thyristor modules, upgrades filtering circuits, and adds ferrite cores and shielded cabling to suppress EMI. We test the controller under typical VFD switching noise to ensure robust operation in noisy industrial environments common across Indian manufacturing plants.
How do I send my ETA ELECTRIC 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 ETA ELECTRIC 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 ETA ELECTRIC 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 ETA ELECTRIC 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.
