Kraus & Naimer 4-Pole Surface Isolator Switch IP65, 40A, 5.5W

Kraus & Naimer KG41B.T904/GBA021.VE 4-Pole Surface Isolator Switch offers reliable switching capability with a 40A switching current and 5.5W switching power. It is equipped with an IP65 rating, making it suitable for harsh industrial, manufacturing, HVAC, and electrical installations where dust and water ingress resistance is critical.

This isolator switch supports a 3-phase electrical system with a mounting surface design. It features a black and silver colored handle that is padlockable in the OFF position (up to 4 padlocks), enhancing operational safety. The switch is door interlocked to prevent the panel door from opening while in the ON position, adding an extra layer of protection for maintenance personnel.

The device includes two normally open auxiliary contacts: one closes in position 1, and the other closes in position 2, enabling precise signaling and control within connected automation systems. The terminals are fingerproof, designed for secure wire connections, supporting current ratings from 20 to 63A.

Standards compliance includes BS EN 60947-3, EN60947-3, IEC 60947-3, VDE 0660, and EN 60204-1, underscoring the product’s adherence to global safety and performance benchmarks. This switch is ideal for industrial electrical panels, automation setups, and application scenarios requiring robust electrical disconnection and isolation functionalities.
