ABB Breaker Lock added to Fortress switchgear interlocks

The ABB Breaker Lock has been added to the existing Fortress range of switchgear interlocks and forms an essential part of a sequential interlocking system that ensures the safe operation of electrical switchgear.

The lock is constructed of zinc alloy with internal contact surfaces made of stainless steel. It is heavy duty and suitable for high-frequency applications, tested to a million operations. It offers in more than 200,000 non-masterable combinations; although a limited number of masterable locks are available for some applications.

The key moves the spindle clockwise with smooth rotation, with the key freed at the ‘12 o’clock’ position for ease of operation. A spring-loaded stainless steel dustcover is available as an option for standard locks, along with a low-profile key designed to fit under such covers.

The lock is designed for use with the entire Sace Emax range.
