GE0400B - 3P SWITCH DISCONNECTOR W/BS FUSE HOLDER

Why Choose the GE0400B?

Lovato GE0400B is a three-pole switch disconnector with BS fuse holder for AC applications, providing 400 A Ith and reliable isolation. Rated insulation voltage is 1000 V with 12 kV impulse withstand, and it suits screw-on-plate mounting. With AC21A, AC22A and AC23A duties supported up to 400 A, it delivers consistent performance in control panels and distribution assemblies.

Designed for demanding environments, GE0400B features 100 kA conditional short-circuit current, 4000 A making and 3200 A breaking capacity at AC23A 400 V, plus mechanical life of 10,000 cycles. Rated operational power is 220 kW at 400 V and 250 kW at 690 V (AC23A). IP20 frontal protection, operating temperature from -25 to 55 °C, altitude up to 3000 m, and compliance with IEC/EN 60947-1 and 60947-3 support safe, standards-aligned installations.
