Product details

Overview

The LC2K0910B7TQ is a Schneider TeSys K reversing contactor, order code LC2K0910B7TQ, built as a mechanically interlocked pair of 3-pole contactors rated for 20 A switching current and a 24 V AC 50/60 Hz coil. It handles motor loads up to 5 hp at 690 V supply and carries certifications including UL, CSA, CCC, EAC, CE, and UKCA, making it suitable for global panel builds.

This reversing contactor integrates two 3-pole contactors with a mechanical interlock that prevents simultaneous closure, a requirement for reversing motor starters where both contactors must never energise at the same time. The 24 V AC coil draws 1.3 W at 50/60 Hz and lacks a built-in bidirectional peak limiting diode suppressor, so external suppression is recommended for inductive load switching. Rated for utilization categories AC-1, AC-3, and AC-3e, the LC2K0910B7TQ is suited for resistive loads and standard squirrel-cage motor starting. The shock tolerance is 10 gn with the contactor closed and 6 gn when open, which informs mounting orientation and vibration isolation in mobile or high-impact installations.

Applications

Reversing contactors of this class are used wherever a motor must run in both directions — conveyor belts, hoists, winches, door operators, and pump reversing stations. The AC-3 rating covers starting and stopping of three-phase induction motors under load, while AC-1 covers resistive heating or lighting banks.

The LC2K0910B7TQ is an active, in-production part within Schneider's TeSys K range. It holds certifications under CB Scheme, CCC, UL, CSA, EAC, CE, and UKCA, and is manufactured to EN/IEC 60947-4-1, GB/T 14048.4, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. No end-of-life notice is indicated.
