GE0250BT4 - 4P SWITCH DISCONNECTOR W/BS FUSE HOLDER

Why Choose the GE0250BT4?

Lovato’s GE0250BT4 is a four-pole switch disconnector with BS fuse holder for secure isolation and protection in AC applications. Delivering 250 A Ith with Ui 1000 V (IEC/EN) and Uimp 12 kV, it offers robust performance in panel assemblies. The screw-on plate mounting and IP20 frontal degree support straightforward integration while maintaining operator safety and clear segregation.

Designed for heavy-duty switching, it carries Ie 250 A for AC21A and AC22A up to 690 V, and 200 A at AC23A 690 V. With 100 kA conditional short-circuit rating, 2500 A making and 2000 A breaking (AC23A 400 V), and 10,000 mechanical cycles, it delivers assured durability. Operates -25 to 55 °C, IP20 front, Pollution Degree 3, plate-mount, and conforms to IEC/EN 60947-1/-3.
