GE0250B - 3P SWITCH DISCONNECTOR W/BS FUSE HOLDER

Why Choose the GE0250B?

Lovato’s GE0250B is a robust three‑pole switch disconnector with BS fuse holder, designed for reliable AC isolation in industrial panels. Rated at 250 A Ith and supporting Ui to 1000 V with 12 kV impulse withstand, it performs across AC21A, AC22A and AC23A duties. Screw‑on plate mounting and IP20 frontal protection suit enclosed assemblies and controlgear.

Consistent current capability is maintained at 250 A for AC21A and AC22A up to 690 V, with AC23A duty supported to 200 A and operational power to 160 kW at 690 V. With 100 kA conditional short‑circuit current, 10,000 mechanical cycles and 24 Nm maximum terminal torque, the GE series ensures secure isolation. Conforms to IEC/EN 60947‑1 and 60947‑3.
