Power-Zone 4 Arc Resistant
Low voltage metal-enclosed, drawout switchgear designed to contain the effects of arc flash events inside the gear per ANSI/IEEE standard C37.20.7.
Overview
Features
>Arc flash energy containment occurs on the front, back, and sides, even when the instrument compartment door is open, complying with ANSI Type 2B rating. This simple, stand-alone circuit breaker solution is a space saving design that offers an additional level of protection for personnel. Plus, Power-Zone 4 Switchgear features simple installation and reduced maintenance and inspection requirements.
