Overview
The LC1G185EHEA is a Schneider TeSys Giga IEC contactor, order code LC1G185EHEA, rated for 305 A switching current with a 130 V coil and 3-pole 3NO configuration. It covers utilization categories AC-1 through AC-8 and DC-1, DC-3, DC-5, suitable for resistive, motor, and mixed loads.
The built-in bidirectional peak-limiting coil technology holds the coil at 130 V DC nominal, with an average impedance of 0.00017 ohm and a power consumption of 8.9 W during continuous operation. Operating time is 40 ms, and the breaking capacity (Icu) is 1.61 kA, sufficient for fault clearing in most motor branch circuits. The contactor is rated for 1000 V insulation and 8000 V impulse withstand. Spring-loaded terminals accept conductors at a pitch of 35 mm; tightening torque is 18 N.m (159.3 lbf.in). The front face with shrouds carries an IP2X rating per IEC 60529 and VDE 0106.
Applications
This contactor class is used in motor control centers, pump and compressor panels, HVAC equipment, and industrial machinery where high-current switching (up to 305 A) and compliance with IEC/UL standards are required. Typical applications include resistive heating loads (AC-1), squirrel-cage motors (AC-3), and plugging/inching duty (AC-4), as well as DC load switching for brake coils or DC drives.
The LC1G185EHEA is an active production part within the TeSys Giga series. It carries multiple international certifications: EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. The contactor also meets IEC 60335-1 Clause 30.2 and IEC 60335-2-40 Annex JJ for appliance and HVAC applications, and is marked with protective treatment TH for tropical environments.
