Selection Guide
Use the table below to select the correct TeSys D contactor for your motor load:
- Up to 75 kW @ 400V → LC1D115M7C (115A)
- Up to 90 kW @ 400V → LC1D170M7C (170A) ← This model
- Up to 110 kW @ 400V → LC1D185M7C (185A)
- Up to 132 kW @ 400V → LC1F185M7C (TeSys F, 185A)
Coil voltage suffix guide: M7 = 220V AC | B7 = 24V AC | BD = 24V DC | E7 = 48V AC | F7 = 110V AC | Q7 = 380V AC

Replacement & Compatibility FAQ
Q: Can I replace LC1D170M7C with LC1D150M7C?
A: Only if your motor load is within the 150A AC-3 rating. For 90 kW @ 400V motors, the 170A rating is required.
Q: Is the LC1D170M7C compatible with TeSys D overload relays?
A: Yes. Use LRD3369 (132–220A range) for direct mounting without adapter.
Q: Can I use an ABB or Siemens equivalent in an existing TeSys D panel?
A: Functionally possible, but mounting holes and busbar connections may differ. We recommend sticking with the original or a verified TeSys-compatible replacement.
Q: Do you supply the coil replacement kit separately?
A: Yes. The coil kit for LC1D170M7C is available as a spare part. Contact us with your coil voltage requirement.
Q: What is the difference between LC1D170M7C and LC1D170M7?
A: The suffix “C” denotes the standard IEC version with screw terminals. Both are functionally identical in most applications.
