AMPERITE Product Lines We Repair
Our engineers are trained on the full AMPERITE product range. Below are the major product families we service.
Thermal Cutout Protectors (TCP Series)
Bimetal-based thermal protection devices that open circuits when motor or device temperature exceeds setpoint. Common faults include stuck contacts, drift in trip temperature, and loss of thermal sensitivity due to age or contamination.
Solid-State Time Delay Relays (SSTD Series)
Electronic timing modules providing ON-delay, OFF-delay, and interval timing functions. Failures typically involve capacitor degradation, transistor leakage, and erratic timing outputs in high-temperature environments.
Bimetal Strip Protectors (BSP Series)
Electromechanical overcurrent and overtemperature protection for pump motors and compressors. Repair needs include contact resurfacing, spring tension correction, and calibration of trip point setters.
Thermal Motor Protectors (TMP Series)
Compact thermal protectors for single and three-phase motor protection. Issues include thermal element brittleness, manual reset lever jamming, and electrical continuity loss in terminal blocks.
Precision Relay Modules (PRM Series)
Electromagnetic relay modules with precision contact arrangements for critical control circuits. Common defects are coil burnout, contact oxidation, and mechanical relay chatter in vibration-prone environments.
Adjustable Time Delay Relays (ATDR Series)
Field-adjustable timing relays for flexible process control. Failures occur due to potentiometer wear, capacitor leakage, and loss of adjustment calibration after years of operation.

Common AMPERITE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AMPERITE equipment arriving at our workshop.
- ✓Thermal element loss of sensitivity or calibration drift — Amperite bimetal strips degrade over years due to thermal cycling, oxidation, and material fatigue. Temperature setpoint can shift 5-15 degrees Celsius, causing premature or late trip action and unprotected motor failures.
- ✓Stuck or welded relay contacts preventing circuit opening — Amperite relay contacts weld due to sustained high inrush currents, arc erosion, or contact material deposition. In humid Indian environments, moisture and industrial dust accelerate contact degradation and increase resistance.
- ✓Time delay relay output erratic or does not function — Amperite solid-state and electromechanical timers fail when internal capacitors dry out, transistors leak, or mechanical escapements jam. High ambient temperatures in Indian plants accelerate capacitor aging and increase leakage current.
- ✓Loss of electrical continuity in terminal blocks or solder joints — Amperite devices suffer vibration-induced cracking of solder joints, corrosion at screw terminal connections, and stress fractures in PCB traces. Industrial vibration and thermal shock in pumping and motor applications accelerate this failure mode.
- ✓Coil burnout in electromagnetic relays and protectors — Amperite relay coils burn due to sustained overvoltage, phase loss in three-phase circuits, or intermittent arcing across coil insulation. Single-phasing in Indian distribution systems is a common trigger for coil failure.
- ✓Manual reset lever jammed or unresponsive — Amperite thermal protector reset levers jam due to mineral deposits in humid climates, corrosion on internal pivot pins, or mechanical deformation from over-pressure or shock. Dust and salt spray in coastal Indian plants accelerate this issue.

Frequently Asked Questions — AMPERITE Repairs
Do you repair Amperite equipment anywhere in India?+
Yes. Synchronics repairs the full Amperite product range including thermal cutouts, time delay relays, bimetal protectors, and relay modules across India. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other major cities. All repairs are completed in our ISO-certified facility in Vadodara, Gujarat, and returned with test reports and warranty.
What is the typical turnaround time for Amperite thermal protector repair?+
Standard Amperite repairs take 5-7 working days from date of arrival. Thermal cutout recalibration, contact resurfacing, and element replacement are our core strengths. Urgent same-day diagnostics are available for critical production shutdowns. All devices are tested for trip point accuracy and thermal responsiveness before dispatch.
Can you calibrate Amperite thermal elements to custom setpoints?+
Yes. Synchronics recalibrates Amperite bimetal strips to your exact trip temperature setpoint using precision ovens and load testing. We provide calibration certificates with uncertainty statements. Custom setpoint changes are common in Indian textile mills and food processing where product or environmental conditions vary seasonally.
What causes Amperite time delay relay output to become erratic?+
Erratic timing in Amperite SSTD and ATDR relays is usually caused by dried-out timing capacitors, leaking transistors, or worn potentiometers. High ambient temperatures and humidity in Indian industrial environments accelerate capacitor aging. Synchronics tests capacitor ESR and leakage current, replaces failed components, and re-measures delay accuracy across the full timing range.
Do you stock replacement parts for Amperite devices?+
Synchronics maintains stock of common Amperite replacement components — bimetal strips, relay contacts, timing capacitors, coil assemblies, and reset mechanisms — for fast repair turnaround. We source original and equivalent Amperite-spec parts from certified distributors. Custom parts and obsolete models are procured on request with extended lead times.
How do I send my AMPERITE 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 AMPERITE 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 AMPERITE 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 AMPERITE 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.
