Lovato GLC0200T4C1 IEC/EN four-pole changeover switch 200A

Why Choose the GLC0200T4C1?

Engineered for dependable source transfer, the Lovato GLC0200T4C1 four‑pole changeover switch delivers 200 A Ith for AC systems. Part of the GLC series, it mounts by screw on plate and conforms to IEC/EN 60947. With Ui 1000 V and Uimp 12 kV, plus AC23A power ratings of 110 kW at 400 V and 200 kW at 690 V, it suits demanding installations.

High endurance and protection come as standard: conditional short‑circuit current is 100 kA with gG/200 fuse coordination, and AC23A making/breaking capacities at 400 V are 2000 A/1600 A. Rated for 20000 mechanical cycles, it accepts 70–185 mm² conductors, tightening torque 15–22 Nm. Operates from −25 to +55 °C, stores −40 to +70 °C, to 3000 m altitude.
