Application-Specific FAQ
Q: Can the LC1D12M7C be used for star-delta starting?
A: Yes. Use three LC1D12M7C units with LAD9R3 mechanical interlocks and an LT3SA00 star-delta timer module for a complete soft-start solution.
Q: What overload relay pairs with this contactor?
A: The LRD16C (9–13A) is the standard pairing for 5.5 kW motors. For higher FLA motors, use LRD21C (12–18A).
Q: Is the LC1D12M7C suitable for capacitor bank switching?
A: No — capacitor switching requires AC-6b rated contactors. Contact us for the correct model.
Q: Can I replace a legacy LC1D12 with LC1D12M7C?
A: Yes. The LC1D12M7C is the current catalog replacement for legacy LC1D12 variants with 220V AC coils. Mounting and wiring are identical.
Q: What is the difference between LC1D09M7C and LC1D12M7C?
A: The LC1D09 is rated 9A / 4 kW; the LC1D12 is rated 12A / 5.5 kW. Both share the same TeSys D frame and accessories.
