Description

LC1K0910B7 is a compact 3-pole TeSys K contactor from Schneider Electric for motor applications. Rated 9A AC-3 4kW@400V, it includes a 24V 50/60Hz AC coil and 1NO auxiliary contact. LC1K0910B7 is a 3-pole TeSys K contactor from Schneider Electric for simple motor applications rated up to 4kW@400V. Very compact, DIN-rail compatible, with connections by screw clamp terminals, it includes a 24V 50/60Hz AC coil and 1NO built-in auxiliary contact. Available worldwide, it complies with multi-standards (IEC, UL, CSA, CCC, EAC, Marine). Very compact, 45mm wide, for DIN-rail and panel mounting. Provides a control circuit compatible with 50Hz and 60Hz supplies and 1NO built-in auxiliary contact. Optimized for simple power applications. Can be completed with auxiliary contact blocks (LA1K, LA2K) and thermal relays (LR2K).

Features

This contactor features a high-efficiency 24V AC coil at 50/60 Hz, making it perfectly compatible with your standard low-voltage industrial control transformer systems. By utilizing a low-draw 4.5 VA hold-in power consumption, it prevents excessive voltage drops and minimizes energy loss inside your electrical enclosure.
This heavy-duty 3-pole configuration safely switches standard AC-3 and AC-3e inductive motor loads up to 9 Amps or 4 kW at 400V, ensuring reliable starting and stopping without arc damage. For non-inductive, resistive heating or lighting control setups (AC-1 duty cycle), the contacts are robust enough to withstand continuous currents up to 20 Amps.
Engineered with a ultra-compact 45mm frame width, the TeSys K series allows you to maximize DIN rail density and pack more functionality into restricted machine footprints. Its flexible physical profile supports both standard 35mm DIN rail snap-on installation and traditional panel screw-fixing, solving tight panel clearance issues without requiring custom layout retrofits.
The contactor comes factory-equipped with one built-in, instantaneous 1 NO (Normally Open) auxiliary contact, giving you immediate feedback routing for PLC inputs, status pilot lights, or secondary control logic circuits. This eliminates the upfront expense and spatial hassle of buying external auxiliary contact add-on blocks for simple automation feedback loops.
Featuring rugged screw clamp terminals designed to hold solid or stranded wires securely, this module maintains high-torque connection integrity even in machinery prone to harmonic vibrations. With an electrical durability rating of up to 1.3 million cycles at nominal load and a mechanical life of 10 million cycles, it drastically reduces maintenance overhead and costly machine downtime.
Built to Schneider Electric's stringent industrial standards, the LC1K0910B7 carries full CE, UL, CSA, CCC, and EAC certifications, guaranteeing compliance with local electrical codes and facility safety inspectors. It also carries the Green Premium badge, verifying full compliance with RoHS and REACH regulations for sustainable, environmentally responsible commercial and industrial operations.
