Industrial control parts supply — encoders, cables and connectors
Circuit breakers and contactors are the switching backbone of every control panel: breakers protect the circuit, contactors do the daily switching under load. When a breaker trips repeatedly or a contactor coil burns out, production stops — and matching the exact frame size, trip curve and coil voltage is what keeps a panel repair to a 15-minute job.
TGK Parts supplies breakers and contactors from ABB, Schneider, Siemens, Eaton, Allen-Bradley and Mitsubishi, in current and obsolete ranges, new and tested surplus.
| MCB - Miniature circuit breakers | 6-125 A, B/C/D curves, 1-4 pole — branch-circuit protection for control panels and machines |
|---|---|
| MCCB - Molded case circuit breakers | 16-1600 A frame, thermal-magnetic or electronic trip — main incomers and motor feeders |
| RCCB / RCD | 30/100/300 mA earth-leakage protection for personnel and equipment safety |
| Motor protection breakers | Manual motor starters with adjustable thermal overload — direct-on-line motor circuits |
| Accessories | Shunt trips, undervoltage releases, auxiliary contacts, DIN rail adapters and terminal covers |
| AC contactors (AC-1/AC-3) | 9-620 A, 24-400 V coils — general purpose and motor switching duty |
|---|---|
| DC contactors | 24-1000 V DC coil and main contacts for battery, traction and DC drive systems |
| Capacitor-duty contactors | Early-make / late-break contacts with damping resistors for power factor correction banks |
| Reversing & star-delta | Mechanically interlocked pairs and timer kits for motor direction and starting control |
| Contactor accessories | Coil modules, surge suppressors, auxiliary contact blocks, mechanical interlocks |
| Item | Detail | Note |
|---|---|---|
| 0.37 kW motor | ≈1 A FLC | 9-12 A AC-3 contactor (e.g. 9 A frame) |
| 1.5 kW motor | ≈3.5 A FLC | 12-18 A AC-3 contactor |
| 7.5 kW motor | ≈15 A FLC | 25-32 A AC-3 contactor |
| 22 kW motor | ≈42 A FLC | 65-75 A AC-3 contactor |
| 55 kW motor | ≈100 A FLC | 150-185 A AC-3 contactor |
Every item is supplied new (sealed), tested surplus or refurbished, with the condition clearly stated before payment. In-stock items ship within 24 hours; obsolete models are sourced through our global surplus network with a quote within 12 hours. All items carry a 12-month warranty.
First check coil voltage vs. actual control voltage and look for chattering (low voltage or dirty pole faces). We can supply the coil module alone if the contactor body is fine.
Not directly — motor feeders need overload protection, typically a motor-protection breaker or breaker plus thermal overload relay. Send the FLC and we confirm the right combination.
Yes — send the complete type code from the nameplate (frame size, trip unit, breaking capacity); we source from the global surplus network and quote within 12 hours.
