GE0251T4 - 4P SWITCH DISCONNECTOR

Why Choose the GE0251T4?

Lovato GE0251T4 is a four-pole switch disconnector for dependable AC isolation in industrial panels. Rated Ith 250 A with Ui 1000 V and Uimp 8 kV, it supports AC-21A/AC-22A/AC-23A duties up to 690 V. Screw-on plate mounting and IP20 frontal protection simplify integration while helping safeguard operators. Part of the GE series, it delivers reliable load breaking and isolation where robust performance and compliance are essential.

With a 2.5 W max power dissipation per pole and 20,000 mechanical cycles, GE0251T4 is engineered for efficiency and durability. AC-23A making/breaking at 400 V is 2500 A/2000 A, with a conditional short-circuit current of 100 kA when protected by a gG250 fuse. Operates from -25 to 55 °C, up to 3000 m altitude, torque to 18 Nm, and meets IEC/EN 60947-1 and 60947-3.
