Rotary switch 2-pole HA-0-A Z-DSU2-H0A 248876

Rotary switch for demanding applications

This two-pole rotary switch from Eaton, designated HA-0-A Z-DSU2-H0A, is a reliable solution for controlling electrical circuits. Designed for durability and safety, it is perfect for both domestic and industrial installations. Its compact design – only 3 modules wide – allows for easy mounting in switchboards.

Functionality and technical parameters

The switch is designed to operate in alternating current (AC) circuits with a rated voltage of up to 690V and a rated current of 20A. Its staircase switch function allows convenient control of lighting from two different points. The short-circuit strength of 10kA provides protection against the effects of sudden overvoltages. The IP20 protection degree guarantees basic protection against touch and ingress of solid objects.

The switch is characterized by the absence of normally open and normally closed contacts, which affects its specific functionality in the circuit. The lack of a signal lamp simplifies the design and increases reliability. The installation depth of 60mm allows for easy adaptation to existing installations. Compliance with DIN VDE 0113 is not enforced, providing greater flexibility in application.

Installation and application

The Eaton Z-DSU2-H0A switch is ideal for applications where a reliable change in the direction of the electrical circuit is required. It will be useful for controlling staircase lighting, fans or other electrical devices. Installation is done by screwing it into the appropriate opening in the switchboard – a width of 3 modules facilitates integration with the existing infrastructure. Installers will appreciate the solid construction and ease of installation, and end-users – trouble-free operation for a long time.
