Lovato GLC0630T4C1 IEC/EN four-pole changeover switch 630A

Why Choose the GLC0630T4C1?

Engineered for reliable source transfer, the Lovato GLC0630T4C1 is a four-pole changeover switch rated to an IEC conventional free air thermal current of 630 A. Designed for AC systems, it offers Ui 1000 V and Uimp 12 kV performance in demanding environments. The screw-on plate installation simplifies panel integration while maintaining compliance with IEC/EN 60947-3, -6-1 and -1 standards.

With AC-23A making 6300 A and breaking 5040 A at 400 V, plus operational power to 355 kW at 400 V and 500 kW at 690 V, this changeover switch delivers dependable load switching. Rated for 80 kA conditional short-circuit current with gG/630 protection, it features 30 to 37 Nm terminal torque, -25 to +55 °C operation, and 10,000 mechanical cycles.
