Fuse disconnect switch 630A, size 3, 3-pole mounting on Sasy 60i, FCL version with box terminals XNH3-FCL-S630-BT 183080

Fuse disconnect switch – reliable installation protection

This three-pole fuse disconnect switch, designed to work with NH3 fuse links, is a key element in protecting the electrical installation. Designed for mounting on 60i rails, it offers solid and safe operation in systems with a voltage of up to 690V AC. The FCL version with box terminals provides convenient and secure connection of wires.

Design and application

This disconnect switch is ideal for use in electrical switchboards, providing effective protection against overloads and short circuits. Its design allows for quick and easy installation, and the ability to connect wires from both the top and bottom increases installation flexibility. The built-in fuse link status control with LED indication allows for quick identification of blown fuses, minimizing system downtime. Short-circuit strength at 120kA (at 500V) or 100kA (at 690V) guarantees reliable operation even in extreme conditions.
