ETI Product Lines We Repair
Our engineers are trained on the full ETI product range. Below are the major product families we service.
EB2 MCB Series
Miniature circuit breaker range for residential and industrial distribution boards. Common faults include nuisance tripping due to loose neutral connections, contact wear after high-fault-current cycles, and bimetal sensitisation in tropical climates affecting thermal settings.
ETIMAT M Contactor Range
Modular 3-phase contactors (AC-3 to 45kW) used in pump drives, compressor motors, and HVAC systems. Typical failures: coil burnout from sustained undervoltage, silver-plated contact degradation, arc chutes fractured by thermal cycling, and mechanical latch seizure from dust ingress.
EATON RCD/RCCB Protection
Residual current devices for personnel and equipment protection in wet industrial environments and food processing plants. Repair involves diaphragm replacement, moving contact calibration, and test button refurbishment after nuisance trips from moisture ingress.
TM Thermal Overload Relays
Bimetal-based overload protection for motor circuits rated 0.63A to 100A. Common issues: sticky reset mechanism after contaminant exposure, inaccurate thermal tripping due to bimetal fatigue, and loose connection tabs causing erratic disconnects.
EDS Modular Switchgear Systems
Compact prefabricated distribution boards for factories, hospitals, and renewable energy installations. Faults include busbar oxidation, terminal block corrosion in coastal plants, and capacitor dielectric breakdown in surge-prone locations.
ETI Surge Arresters and SPD Modules
Surge protection devices for control circuits and VFD inputs. Failure modes: varistor aging under repeated surge stress, MOV element cracking, and gas discharge tube electrode erosion in high-fault-rate installations.
Why Choose Synchronics for ETI 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 ETI equipment.

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 ETI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ETI equipment arriving at our workshop.
- ✓ETI MCB Nuisance Tripping on Inductive Loads — Loose neutral connection in distribution board causing neutral current redistribution through bimetal strip, or in-rush current from soft-starter ramps exceeding thermal threshold. Common in textile mills and pump stations across Maharashtra and Gujarat.
- ✓ETIMAT Contactor Coil Burnout (AC and DC Variants) — Sustained supply voltage sag below 80% rated voltage during monsoon seasons, or prolonged energisation without proper load switching. DC coils fail faster in non-filtered rectifier supplies common in older Indian industrial installations.
- ✓RCD/RCCB Persistent Nuisance Tripping in High-Humidity Zones — Diaphragm corrosion, moisture ingress causing Earth leakage on control circuits, or capacitive coupling from nearby VFD cables inducing phantom Earth faults in food processing and chemical plants.
- ✓Thermal Relay Reset Failure After Trip Event — Bimetal strip permanent deformation from cumulative thermal cycling, or contaminated reset mechanism (lint, salt spray in coastal areas) preventing mechanical catch disengagement.
- ✓Switchboard Busbar Oxidation and Contact Resistance Increase — Copper busbar oxidation in salt-laden coastal environments (Kerala, Karnataka backwaters) or inadequate ventilation in air-tight switch enclosures, causing temperature rise and intermittent connection loss.
- ✓Surge Arrestor MOV Element Failure Under Repeated Transient Stress — Ageing of metal oxide varistor (MOV) elements after 5-10 years in high-frequency surge environments (switching stations, renewable energy farms), or undersized SPD for actual transient energy levels.

Frequently Asked Questions — ETI Repairs
Do you repair ETI equipment anywhere in India?+
Yes. Synchronics repairs the full ETI product range — MCBs, RCCBs, contactors, thermal relays, surge arresters, and modular switchgear systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All repairs processed at our certified facility in Vadodara, Gujarat with same-day diagnostics and 3-5 day turnaround for most assemblies.
Why do ETI MCBs nuisance trip in monsoon season?+
Humidity causes moisture ingress into the bimetal strip chamber, reducing electrical insulation and triggering false thermal trips. Additionally, neutral connection corrosion increases neutral current redistribution through the bimetal. Synchronics inspects neutral terminations, replaces moisture seals, and re-calibrates thermal settings. We also recommend IP67-rated junction boxes for high-humidity zones like coastal textile mills and food plants.
What is your repair warranty on ETI contactors?+
All ETI contactor repairs carry 12 months parts and labour warranty covering coil failures, contact degradation, and mechanical latch issues. We replace silver-plated contacts, rewire coils using original gauge wire, and test mechanical travel at 50% and 110% rated voltage to ensure reliability in Indian industrial duty cycles. Warranty excludes external damage and inappropriate supply voltage.
Can you repair ETI RCD devices tripping on VFD installations?+
Yes. VFD harmonic currents and dV/dt transients often trigger sensitive RCDs. Synchronics installs 30mA AC-type or 'A-type' RCDs rated for VFD environments, and recommends EMI filtering on VFD output cables. We also perform leakage current trending to distinguish genuine Earth faults from phantom trips caused by capacitive coupling. Complete solution typically requires RCD upgrade and cable separation audit.
What is the typical repair cost for an ETI thermal overload relay?+
ETI thermal relay refurbishment (disassembly, cleaning, recalibration, new gaskets) costs approximately INR 800-1200 depending on size class. Complete replacement with new relay is INR 1500-2500. Synchronics provides cost estimate within 24 hours of fault assessment. Bulk repairs for mill shutdowns attract 15-20% discounts. All repairs tested at temperature extremes to ensure reliability in Indian climates.
How do I send my ETI 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 ETI 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 ETI 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 ETI 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.
