        What this product is for

        This fully assembled enclosed circuit breaker is used as a high-amperage disconnect and overcurrent protection device in commercial and industrial power distribution systems. It combines a Noark M4S 600A, 3-pole thermal-magnetic moulded case circuit breaker with a factory enclosure and neutral terminal for 3-phase, 4-wire installations.

        Use for

        Use for main disconnects, large feeders, distribution equipment, service entrance equipment where permitted by design, and industrial control or power systems requiring a 600A enclosed breaker. It is intended for indoor locations with a Type 1 enclosure.

        Avoid for

        Avoid using this enclosure in washdown, corrosive, dusty, or outdoor locations where Type 12 or Type 3R protection is required. Also avoid applications that need a higher interrupting rating than 35kA at 480V or a different pole/wire configuration.

        Best for

        Best for contractors and panel builders who want a factory-assembled enclosed breaker instead of sourcing the breaker, enclosure, and neutral components separately. This can help simplify ordering, coordination, and installation planning on larger distribution jobs.

        Installed in

        Typically installed in electrical rooms, mechanical rooms, commercial service areas, industrial facilities, and indoor distribution spaces. The Type 1 steel enclosure is intended for general indoor use.

        Why this product exists

        This product exists to provide a ready-to-install enclosed breaker solution for higher-amperage systems up to 600V AC. Compared with field-built assemblies, a factory-configured unit can reduce parts matching issues and save labour during installation.

        Compared with similar products

        Compared with a bare MCCB, this unit adds the enclosure and neutral terminal needed for a 3-pole, 4-wire application. Compared with higher-series enclosed breakers, this M4S version is the standard interrupting option in the Noark enclosed breaker range at 35kA at 480V, making it suitable where available fault current does not require the higher 65kA or 100kA options. As a rule of thumb, always confirm available fault current and coordination before selecting an enclosed breaker. Actual suitability depends on system design, utility contribution, conductor length, transformer size, and local electrical code.
