GE0315B - 3P SWITCH DISCONNECTOR W/BS FUSE HOLDER

Why Choose the GE0315B?

The Lovato GE0315B is a three‑pole switch disconnector with BS fuse holder designed for reliable isolation and load switching in AC systems. Rated Ith 315 A and suitable for plate mounting, the GE0315B delivers robust performance across industrial panels. With Ui 1000 V and Uimp 12 kV, it provides strong dielectric capability while maintaining IP20 frontal protection and compliance with IEC/EN 60947‑1 and 60947‑3.

Engineered for demanding duties, it carries AC21A and AC22A currents of 315 A up to 690 V, and AC23A ratings of 315 A at 400/500 V (250 A at 690 V). High endurance is assured with 10,000 mechanical cycles, 100 kA conditional short‑circuit withstand, and 3150 A making/2600 A breaking (AC23A 400 V). Suitable for environments from −25 to +55 °C and altitudes to 3000 m, with plate‑mount screw installation.
