Lovato GL0250C1 IEC/EN three-pole switch disconnector 250A

Why Choose the GL0250C1?

The Lovato GL0250C1 is a three-pole switch disconnector engineered for safe AC isolation and load switching. Rated Ith 250 A with Ui 1000 V and Uimp 12 kV, it delivers robust performance across demanding installations. Designed for flexibility, this GL series device mounts via screw on plate or standard 35 mm DIN rail and conforms to IEC/EN 60947-3 and 60947-1.

High utilitarian ratings support heavy duty switching: AC23A currents of 250 A at 400–690 V and 135 A at 1000 V, with 2500 A making and 2000 A breaking at 400 V. The device achieves a conditional short-circuit current of 100 kA with gG/250 fuses, offers 20,000 mechanical cycles, and operates from -25 to +55 °C up to 3000 m altitude.
