HBL Product Lines We Repair
Our engineers are trained on the full HBL product range. Below are the major product families we service.
HBL Modular Switches and Socket Outlets
HBL's iconic modular wiring devices including switches, sockets, and dimmers used in residential, commercial, and light industrial installations. Common faults include contact corrosion, mechanical wear, and electrical tracking on high-load circuits.
HBL Industrial Control Panels and Distribution Boards
Custom-built MCCs, ACBs, and distribution systems for manufacturing plants. Repair involves breaker recalibration, busbar inspection, relay replacement, and thermal imaging for overload detection.
HBL Motor Control and Automation Equipment
Soft-starters, contactors, overload relays, and motor protection circuits. Common failures include coil burnout, contact pitting, and nuisance tripping under inductive loads.
HBL Wiring Devices and Panel Components
Terminal blocks, connectors, DIN rail mounting hardware, and modular inserts for switchboards. Issues stem from vibration loosening, corrosion in humid environments, and improper earthing.
HBL Surge Protection and Safety Devices
SPD modules, isolators, and safety switches integrated into control panels. Failures occur due to voltage transients, component aging, and incorrect coordination with upstream MCB ratings.
Why Choose Synchronics for HBL Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on HBL equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common HBL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HBL equipment arriving at our workshop.
- ✓HBL switch contact pitting and arc erosion — High inrush currents in inductive circuits or frequent switching under load cause tungsten alloy contacts to pit and erode, increasing resistance and heat generation. Moisture ingress accelerates oxidation.
- ✓HBL modular insert frame cracking or jamming — Thermal cycling in hot industrial environments or over-torquing of terminal screws stresses the phenolic or plastic insert frame, causing micro-fractures or mechanical binding of the moving arm.
- ✓HBL distribution board busbar corrosion and voltage drop — Coastal or high-humidity environments in India cause oxidation of copper/aluminum busbars. Vibration loosens bolted connections, increasing contact resistance and causing localized heating.
- ✓HBL motor contactor coil burnout and chatter — Supply voltage fluctuations (common in Indian industrial plants), missing shading coils, or mechanical debris jamming the armature cause coil insulation degradation and chattering, leading to complete failure.
- ✓HBL thermal overload relay nuisance tripping — Incorrect thermal element selection for motor FLC, loose terminal connections reducing effective current sensing, or calibration drift after years of operation cause false trips and production downtime.
- ✓HBL SPD surge suppressor failure after lightning transient — Uncoordinated earthing, missing neutral-earth bonding, or cascading surges overwhelm MOV or cartridge elements. Failure can leave the circuit unprotected or create short-circuit hazards.

Frequently Asked Questions — HBL Repairs
Do you repair HBL equipment anywhere in India?+
Yes. Synchronics repairs the full HBL product range—modular switches, distribution boards, motor contactors, thermal relays, and control panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Ahmedabad, Hyderabad, Bangalore, Chennai, Kolkata, and all other major cities. Repairs are carried out at our ISO 9001 facility in Vadodara, Gujarat, with full traceability documentation.
What is the typical turnaround time for HBL switchgear repair?+
Standard HBL repairs take 5-7 working days including diagnostics, component replacement, and testing. Modular switch repairs are often same-day or next-day. Emergency breakdowns can be expedited within 24-48 hours. We provide interim loaner equipment for critical control panels to minimize production loss.
Can you supply genuine HBL spare parts, or do you use equivalents?+
Synchronics maintains authorized HBL component inventory including contact sets, coils, thermal elements, and insert frames. Where genuine parts are unavailable, we use ISO-certified equivalents with third-party verification for performance matching. All replacements are documented on the repair certificate with part numbers and specifications.
How do I know if my HBL distribution board needs repair or replacement?+
Signs of failure include nuisance MCB tripping, visible burn marks on busbars, loose terminal connections, overheating during normal operation, or difficulty operating switches. Synchronics offers free diagnostic assessment. If repair cost exceeds 60% of replacement value, we recommend replacement with proper decommissioning of old board.
Do you certify HBL repairs for warranty or compliance purposes?+
Yes. Every HBL repair by Synchronics includes a detailed test report with before/after electrical measurements, component changes, and functional verification. Reports comply with IS 4365, IS 8623, and HBL quality standards. Certificates are provided for audit, compliance, and equipment history records.
How do I send my HBL 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 HBL 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 HBL 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 HBL 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.
