Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The LC2K12004B7 is a Schneider TeSys K reversing contactor, 4-pole, rated for a switching current of 20 A in AC-1 utilization category and a supply voltage of 690 V. This reversing contactor mechanically interlock two contactors to control motor direction without a separate reversing starter. The 4-pole configuration switches three phases and the neutral, common in North American and some European motor circuits. The 20 A AC-1 rating covers resistive and lightly inductive loads; for motor starting (AC-3), derate per the manufacturer's curve. Breaking capacity reaches 110 A at 440 V and 70 A at 690 V per IEC 60947, giving headroom for fault clearing. The coil pulls in at 24 V AC 50/60 Hz with a typical operating time of 10 ms and a maximum operating rate of 3600 cycles per hour. Electrical life is 0.3 million cycles at 20 A AC-1, 440 V. ## Applications Reversing contactors of this class are used in motor control centers and standalone panels for conveyors, hoists, pumps, and fans that require forward/reverse operation. The preassembled reversing busbar reduces wiring time and panel space. Typical environments include industrial machinery, HVAC, and material handling. The LC2K12004B7 belongs to the TeSys K range, Schneider's compact contactor family for control and light power applications up to 20 A. It is specified by panel builders and OEMs who need a space-saving reversing contactor with mechanical interlock and global certifications (IEC, UL, CSA). The preassembled busbar distinguishes it from field-assembled reversing kits. The LC2K12004B7 is an active production part within the TeSys K range. It carries certifications per EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. The unit is California Proposition 65 compliant and has a flammability rating of V1 per UL 94. Standard warranty is 18 months.","metaTitle":"Schneider LC2K12004B7 TeSys K Reversing Contactor, 4-Pole, 20 A, 24 V AC","metaDescription":"Schneider TeSys K LC2K12004B7 reversing contactor: 4-pole, 20 A switching current, 24 V AC coil, 690 V supply, IP20.
