Replacement & Compatibility FAQ
Q: Can I replace LC1D38M7C with LC1D40M7C?
A: Yes, the LC1D40 is a direct form-fit replacement with a slightly higher 40A rating. Terminal positions and mounting dimensions are identical within the TeSys D frame.
Q: Is the LC1D38M7C compatible with TeSys D overload relays?
A: Yes. It directly clips onto LRD-series overload relays (e.g., LRD22C for 16–24A motor protection) without adapters.
Q: What does the “M7” suffix mean?
A: “M7” designates a 220V AC, 50/60 Hz coil. Other suffixes indicate different coil voltages (e.g., BD = 24V DC, F7 = 110V AC).
Q: Can a Siemens 3RT2036 replace the LC1D38M7C?
A: Electrically yes (same current rating and coil voltage available), but terminal labeling and accessory mounting differ. Verify panel wiring diagrams before substitution.
Q: Is this contactor suitable for capacitor switching (AC-6b)?
A: No. The LC1D38M7C is rated for AC-3 (motor loads). For capacitor banks, use dedicated capacitor switching contactors (LC1DWK series).
