AIRPAX Product Lines We Repair
Our engineers are trained on the full AIRPAX product range. Below are the major product families we service.
AIRPAX Thermal Circuit Breakers (TCB)
Temperature-sensitive thermal bimetal breakers for motor overload protection. Common repair issues include bimetal calibration drift, nuisance tripping at normal load, and failure to trip during genuine overload conditions due to ambient temperature sensitivity.
AIRPAX Magnetic Breakers
Fast-acting electromagnetic breakers for short-circuit protection in high-current industrial circuits. Repairs address stuck solenoid plungers, loss of magnetic force, arcing erosion on contacts, and failure to clear faults within specification.
AIRPAX Dual-Action Breakers (Thermal-Magnetic)
Combined thermal and magnetic protection in single modules for motor feeders and branch circuits. Faults include independent failure of thermal or magnetic element, nuisance trips from harmonic-rich loads, and contact contamination.
AIRPAX Auxiliary Switch Modules
Mechanical and electrical switching aids for breaker status indication and remote control. Common issues: worn cam followers, sticking switch contacts, spring fatigue, and loss of signal reliability in networked control panels.
AIRPAX Power Distribution Blocks
Bus bars and terminal blocks used to connect multiple breakers in industrial enclosures. Repair focuses on loose terminations causing arc flash risk, corrosion in humid environments, and vibration-induced contact separation.

Common AIRPAX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AIRPAX equipment arriving at our workshop.
- ✓Thermal bimetal calibration drift exceeding tolerance — AIRPAX thermal breakers lose calibration over 10-15 years due to bimetal metal fatigue and repeated thermal cycling. Operating in high-temperature plants (textiles, foundries) accelerates drift, causing breaker to trip at 85% of rated load instead of 110%.
- ✓Nuisance tripping on cold mornings or ambient temperature swings — AIRPAX thermal breakers are temperature-compensated but can misfire if the compensation spring weakens or the breaker is installed in poorly controlled plant environments. Indian industrial plants with open-sided bays experience 15-25°C overnight swings, triggering phantom trips.
- ✓Magnetic coil loss of force, breaker fails to trip during short-circuit — AIRPAX magnetic coils degrade due to coil winding insulation breakdown (moisture ingress), loose core laminations, or physical impact. Harmonic-rich power supplies (VFD mills, welding plants) add electromagnetic stress, weakening the solenoid pull-in force below trip threshold.
- ✓Contact arcing erosion preventing reliable electrical closure — AIRPAX breaker contacts (silver-alloy or copper-silver) erode after hundreds of short-circuit interruptions or sustained arcing under high-inductance loads (motor starting, transformer inrush). Pitting and microstructural changes reduce contact pressure and increase contact resistance.
- ✓Auxiliary switch mechanism sticking or failing to signal breaker status — AIRPAX auxiliary switch modules wear after 50,000+ mechanical cycles. Worn cam followers bind, switch spring tension weakens, or dust/moisture enters sealed contacts in humid plant environments (pharmaceutical, food processing). Signal loss disrupts breaker monitoring in networked control systems.
- ✓Loose or corroded terminal connections causing high contact resistance and heat — Vibration in running machinery (pumps, conveyors, compressors) gradually loosens the set-screw terminals on AIRPAX breaker lugs. Moisture and salt air in coastal or humid regions (Mumbai, Chennai, Kolkata plants) corrode copper terminals and aluminum bus bar connections, raising resistivity.

Frequently Asked Questions — AIRPAX Repairs
Do you repair AIRPAX equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full AIRPAX circuit breaker and thermal protection portfolio across India. We offer PAN India door pickup and logistics from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and tier-2 industrial cities. All repairs are done at our main facility in Vadodara, Gujarat, with 5-10 business day turnaround for most AIRPAX breakers.
How do you test AIRPAX thermal breakers after calibration?+
Synchronics uses precision thermal chambers to simulate operating temperatures from 0 to 60°C and measure trip current at each setpoint. We validate that the breaker trips within AIRPAX factory tolerance bands (typically ±5% of rated current). We also perform mechanical cycle testing to ensure the mechanism moves freely before the breaker leaves our facility.
Can AIRPAX breakers be repaired if contacts are heavily pitted?+
Yes, if contact pitting is not too severe. Synchronics measures contact resistance with certified instruments. If resistance is below 1.0 milliohm and pitting is light, we file and smooth the contacts. If pitting is deep or contact resistance exceeds limits, we replace the entire contact cartridge with OEM-matched parts to restore reliability.
What is the cost of AIRPAX breaker repair versus buying new?+
AIRPAX breaker repair typically costs 40-60% less than new replacement, especially for older models (1990s-2000s) that are no longer mass-produced. Synchronics provides upfront quotation after diagnosis. Repair includes recalibration, contact conditioning, full testing, and warranty. For mission-critical breakers in textile mills and power plants, repair is faster than lead-time on new stock.
Do AIRPAX breakers need maintenance while in service?+
AIRPAX breakers are low-maintenance but benefit from preventive care. Synchronics recommends annual visual inspection for corrosion, loose terminals, and cleanliness. If your plant operates in coastal, high-humidity, or high-vibration environments (foundries, ports, spindle mills), inspect every 6 months. Clean terminal contacts with isopropyl alcohol and check set-screw torque. Send for full recalibration every 5-7 years or after repeated trip cycles.
How do I send my AIRPAX 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 AIRPAX 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 AIRPAX 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 AIRPAX 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.
