3-pole disconnector 80 A in OB4 with yellow-red lockable front RSI-3080-OB4\ZC

Isolator switch – safety and control in your installation

This 3-pole switch with a rated current of 80A is a reliable solution for disconnecting power in three-phase installations. Designed as a main switch, it provides complete circuit isolation during service, maintenance or emergency work, protecting both equipment and personnel. Its robust construction and high electrical parameters make it an ideal choice for both professionals and demanding end-users.

Functionality and application

The device is designed for safely disconnecting three-phase circuits with a voltage of up to 690V AC and a current of 80A. It will be useful in control cabinets, industrial switchboards, commercial buildings and anywhere where reliable power isolation is required. The rated switching power of 35 kW (AC-23 at 400V) allows for safe disconnection of electric motors and other inductive loads. High short-circuit resistance (6 kA) further increases safety.

Construction and characteristic features

The switch has three poles (3P) and an intuitive black-red knob, providing easy operation and clear status indication (ON/OFF). Solid screw connections guarantee a secure electrical contact and minimize the risk of failure. The IP20 degree of protection of the front part provides basic protection against access to hazardous elements. The device is designed for permanent mounting, ensuring stability and durability of the entire installation. Additionally, the ability to mount the knob outside the housing makes operation easier in hard-to-reach places. The device's construction allows for quick mounting on a rail or mounting plate.
