⚡ Key Features

9 A AC-3 rated — suits up to a 4 kW squirrel-cage induction motor at 415V for direct-on-line (DOL) starting and running.
24V 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.
Reversing duty — mechanical and electrical interlock between the two contactors prevents both from closing simultaneously, which would cause a phase-to-phase short circuit.
TeSys K compact series — smaller body than TeSys D for space-limited panels; direct clip mounting on TeSys K LRK overload relays; accepts LA1KN auxiliary contacts.
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.

❓ Frequently Asked Questions

Q: Is the LC2K0910B7 rated 9 A for AC-3 motor duty or AC-1 resistive duty?

A: The 9 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 LC2K0910B7 has a coil voltage of 24V AC — what control supply is needed?

A: This Schneider Electric device requires a 24V 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 1 NO (Normally Open) contacts of the LC2K0910B7 switch at 440V AC?

A: The 1 NO (Normally Open) contacts on the LC2K0910B7 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 the LC2K0910B7 be used for reversing duty (forward/reverse motor control)?

A: Contactors used for reversing must be wired with two contactors interlocked so only one can energise at a time. The Schneider Electric series provides mechanical interlock kits that physically prevent both contactors from closing simultaneously — mandatory for reversing and brake applications to prevent phase-to-phase short circuits.

Q: Can multiple LC2K0910B7 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.
