ABB OS series switch fuses Switchgear OS switch fuses

ABB offers AC and DC rated switch-disconnectors suitable for diverse applications such as machinery, power distribution, switchboards, motor control centers or photovoltaic installations. 

The ABB OS series switch fuses are designed for use in low-voltage switchgear, suitable for various industrial and commercial applications. They are mainly used to distribute power and protect motors, cables, and other devices from short-circuits and overloads. Here is a detailed introduction:

Features of ABB OS series switch fuses

Excellent Protection Performance: With a rated breaking capacity of up to 100 kA, they can quickly cut off the circuit when a short - circuit or overload fault occurs, protecting equipment and personnel safety.

Compact Design: The unique short - current path and double - sided spring structure, combined with fewer components, make the overall volume small, which can save installation space and is suitable for installation in confined spaces.

Flexible Installation: It can be base-mounted, door-mounted, or DIN-rail-mounted, and can be installed in any direction, such as horizontally, vertically, or even on the ceiling. In addition, switches from 16 to 125 amperes can be snap-on or screw-mounted, and switches from 160 to 4000 amperes have adjustable feet that allow top or side mounting.

Modular Design: The pole-module design enables the operating mechanism to be located in any position, and the direction of the terminals can be adjusted according to the installation needs, which provides convenience for different types of cabinet design.
