GLC0200C1UL - 3P CHANGEOVER SWITCH 200A AC21 UL VERSION

Why Choose the GLC0200C1UL?

The Lovato GLC0200C1UL is a three-pole AC changeover switch engineered for dependable source transfer in industrial and commercial installations. Rated Ith 200 A and built to UL1008, this changeover switch mounts with screw-on plate installation for straightforward panel integration. It enables efficient switching between supplies while supporting continuity and safety for distribution boards, generator changeover, and other critical services.

With Ui 1000 V and Uimp 12 kV, plus AC23A operational power of 110 kW at 400 V and 200 kW at 690 V, the GLC0200C1UL handles demanding AC duties. It offers a conditional short-circuit current of 100 kA, mechanical life of 20,000 cycles, and accepts 70 to 85 mm² conductors, with 15 to 22 Nm terminal torque for secure terminations across -25 to +55 °C, up to 3000 m altitude.
