GE0050FT4 - 4P S-D W/FUSE HOLDER NFC14X51 AC21A 50A

Why Choose the GE0050FT4?

Designed for dependable isolation and protection, the Lovato GE0050FT4 is a four-pole switch disconnector with NFC fuse holder rated at 50 A. Part of the GE series, it supports AC installations and mounts securely via screw-on-plate fixing. Ideal for compact control panels, it delivers straightforward operation and robust build quality to meet demanding industrial switching duties.

Performance is assured across AC21A, AC22A and AC23A duties, with 50 A operating current up to 690 V. The device offers 800 V rated insulation (Ui) and 8 kV impulse withstand (Uimp), IP20 frontal protection, and a 50 kA conditional short-circuit rating. With 10,000 mechanical cycles and an operating range of -25 to 55 °C, it suits diverse environments and loads.
