GE0050F - 3P S-D W/FUSE HOLDER NFC 145X51 AC21A 50

Why Choose the GE0050F?

Lovato GE0050F is a three-pole switch disconnector with NFC fuse holder rated 50 A for AC systems. With Ui 800 V and Uimp 8 kV, it delivers 50 A across AC21A, AC22A and AC23A duties up to 690 V. Screw-on plate installation and IP20 frontal protection simplify panel integration while maintaining safety and reliability for isolation and load switching.

High endurance design offers mechanical life of 10,000 cycles, with 500 A making and 400 A breaking capacity at AC23A 400 V and a 50 kA conditional short-circuit rating. Rated operational power is 25 kW at 400 V and 42 kW at 690 V. Operates from -25 to 55 °C, up to 3000 m altitude, meeting IEC/EN 60947-1 and 60947-3.
