GE0630B - 3P SWITCH DISCONNECTOR W/BS FUSE HOLDER

Why Choose the GE0630B?

The Lovato GE0630B is a three-pole switch disconnector with BS fuse holder designed for dependable isolation in three-phase AC systems. Rated to 630 A Ith, this GE series device combines robust switching with integrated fuse accommodation to streamline protection and maintenance. It mounts via screw-on plate, making it suitable for panel builders and OEMs seeking a compact, high-capacity switch disconnector for distribution, motor control, and heavy-duty industrial circuits.

Engineered for tough environments, the GE0630B delivers Ui 1000 V insulation and 12 kV impulse withstand, with AC21/AC22 utilisation categories at 630 A up to 690 V. In AC23 duty it supports 630 A at 400/500 V and 400 A at 690 V, with a conditional short-circuit current of 100 kA. Frontal IP20 protection, pollution degree 3, and a mechanical life of 5,000 cycles ensure reliable service from −25 to +55 °C up to 3,000 m altitude.
