Schneider Electric LC1D115M7C 115A AC Contactor – TeSys D Series
When a high-current AC contactor fails mid-operation, the consequences cascade instantly: motors stall, production lines halt, and every minute of downtime translates directly into lost revenue and safety risk. In heavy-duty motor control applications running at 115A, there is no acceptable substitute for a proven, specification-grade contactor. The Schneider Electric LC1D115M7C is engineered precisely for these mission-critical moments — delivering reliable switching performance where failure is not an option.
Within the globally trusted TeSys D series, the LC1D115M7C occupies the upper tier of the standard contactor range, rated at 115A AC-3 for squirrel-cage motor loads. TeSys D is the world’s most widely deployed contactor platform, with installations across manufacturing, infrastructure, and energy sectors on every continent. The LC1D115M7C’s 220V AC (M7) coil voltage makes it the preferred choice for European and Asian industrial power systems, and its IEC 60947-4-1 compliance ensures seamless integration into certified control panels worldwide.

Frequently Asked Questions
Q: What is the difference between LC1D115M7C and LC1D115B7C?
A: The suffix letter before “C” denotes the coil voltage. M7 = 220V AC 50/60Hz; B7 = 24V AC 50/60Hz. All other electrical and mechanical specifications are identical. Ensure your control circuit voltage matches the coil rating before ordering.
Q: Can the LC1D115M7C be used for AC-4 (plugging/inching) duty?
A: Yes, TeSys D contactors are rated for AC-4 duty, but the current rating is derated. Consult the TeSys D selection guide (Schneider document reference: MKTED210045EN) for AC-4 derating curves specific to your application.
Q: Is the LC1D115M7C compatible with a star-delta starter configuration?
A: Yes. Three LC1D115M7C units (or a combination with smaller contactors for the star leg) can be configured with the LAD9R1 mechanical interlock and LADR2 timer module to form a complete star-delta starter for motors up to 55kW at 400V.
Q: What overload relay should I pair with the LC1D115M7C?
A: The LRD3365 (63–80A) or LRD3375 (70–90A) are common pairings depending on motor FLA. For motors near the 115A limit, consult Schneider’s TeSys D selection tool or contact our technical team for a recommendation.
Q: Do you provide a certificate of conformity or test report?
A: Yes. Documentation including certificate of conformity is available upon request for project and tender requirements. Please specify your documentation needs when submitting your inquiry.
Q: What is the minimum order quantity (MOQ)?
A: There is no strict MOQ for standard orders. Single-unit orders are accepted. Volume pricing is available for orders of 5 units or more.
