General Applications

Solution for where space is at a premium or when

equipment dimensions are critical when upgrading

or retrofitting current systems. Offering the power

and performance of a power breaker in the compact

size of a molded case breaker. With its reduced

weight and compact dimensions, you can mount

two times as many feeder breakers and reduce the

overall enclosure density up to 50%.

Enables comprehensive solutions to meet and

exceed the unique and wide-ranging requirements

of today’s global power distribution systems.

Designed and engineered for ultimate custom

configuration and application flexibility in metal

enclosed switchgear and power distribution

enclosures.
