Lovato GLC0630C1 IEC/EN three-pole changeover switch 630A

Why Choose the GLC0630C1?

Engineered for robust power transfer, the Lovato GLC0630C1 three-pole changeover switch delivers dependable AC switching at 630 A Ith. Part of the GLC series, it features screw-on plate installation for straightforward panel integration. Designed to IEC/EN 60947-3, 60947-6-1 and 60947-1, it provides assured performance and safety in demanding industrial environments and power distribution applications.

With Ui 1000 V and Uimp 12 kV, this switch handles heavy-duty duty cycles, offering AC-23A power ratings of 355 kW at 400 V and 500 kW at 690 V. It supports conditional short-circuit current up to 80 kA (gG/630 fuse), 10,000 mechanical cycles, and 30 to 37 Nm terminal torque, operating reliably from -25 to +55 °C up to 3000 m altitude.
