Lovato GLC0500C1 IEC/EN three-pole changeover switch 500A

Why Choose the GLC0500C1?

Built for demanding power transfer duties, the Lovato GLC0500C1 is a three-pole changeover switch designed to IEC/EN 60947. With Ith 500 A and AC operation, this GLC series device offers robust performance and screw-on plate installation. It features Ui 1000 V, Uimp 12 kV, and AC23A power up to 500 kW at 690 V, supported by an 80 kA conditional short-circuit rating with gG/500 fuse protection.

Engineered for reliability, the GLC changeover switch delivers 5000 A making and 4000 A breaking capacity at AC23A 400 V, with low power dissipation of 32.5 W per pole. A mechanical life of 10,000 cycles, terminal tightening torque of 30 to 37 Nm, and an operating range from -25 to +55 °C ensure dependable service up to 3000 m.
