⚡ Key Features

400 A AC-3 rated for motor and resistive load switching at LV.
220V AC coil — connects directly to pushbutton station, PLC digital output, or timer relay; suitable for standard 50Hz Indian industrial control circuits.
3 Poles main contacts with silver-alloy (AgSnO₂) tips — rated for AC-3 duty (DOL motor starting/stopping); low contact resistance reduces heat at rated current.
Main contacts rated up to 440V AC — compatible with 415V AC three-phase Indian supply and 480V AC North American systems.
Manufactured to IEC 60947-4-1 / IS 13947-4-1 — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified, CE marked, RoHS compliant — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Schneider Electric product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: Is the LC1E400M7 rated 400 A for AC-3 motor duty or AC-1 resistive duty?

A: The 400 A rating of this Schneider Electric contactor applies to AC-3 duty (squirrel cage motor starting and running). For AC-1 (resistive/non-inductive) loads, the current can be up to ~1.3× the AC-3 rating. AC-4 (plugging/reversing) requires significant de-rating — consult the Schneider Electric selection table.

Q: The LC1E400M7 has a coil voltage of 220V AC — what control supply is needed?

A: This Schneider Electric device requires a 220V AC control supply connected to the coil terminals (A1 and A2). For AC coils, ensure the control circuit voltage is stable — voltage drops below 85% of rated coil voltage can cause chatter and coil overheating. Always fit a surge suppressor across the coil when switching with a PLC or solid-state relay.

Q: What circuit can the 3 NO (Normally Open) contacts of the LC1E400M7 switch at 440V AC?

A: The 3 NO (Normally Open) contacts on the LC1E400M7 are rated for switching at up to 440V AC. These auxiliary contacts are typically used for: (1) indication lamps and buzzers, (2) PLC input feedback to confirm device state, (3) interlocking with other contactors or relays in control circuits. Check the current rating of the auxiliary contact (typically 10A at 250V AC) — do not use for power load switching.

Q: Can multiple LC1E400M7 contactors be wired for star-delta starting?

A: Yes. Star-delta starters use three contactors: main (KM1), star (KM2), and delta (KM3). The Schneider Electric contactor series supports mechanical and electrical interlocking accessories that prevent simultaneous energisation of star and delta contactors — critical for safety. Ensure all three contactors are rated correctly for the motor FLC and star-delta transition current.

Q: What is the electrical and mechanical life of the LC1E400M7?

A: Schneider Electric contactors are rated for millions of operations: typically 10–30 million mechanical operations and 1–3 million electrical operations at rated current and voltage (AC-3 duty). High-frequency switching applications (>10 operations/hour) require checking the specific thermal capacity of the contactor for continuous duty without overheating.
