        What this product is for

        This fully assembled enclosed circuit breaker provides feeder or branch circuit protection where a breaker needs to be mounted independently from switchboards or panelboards. It combines a NOARK M3S 400A molded case circuit breaker with a Type 1 indoor steel enclosure for commercial and industrial distribution systems.

        Use for

        Use for indoor feeder protection, equipment isolation, distribution panels, machinery supply, and commercial service distribution where a 3-pole, 4-wire enclosed breaker is required. Suitable for applications up to 600V AC where a 35kA rating at 480V meets the available fault current.

        Avoid for

        Avoid using this enclosure outdoors, in washdown areas, or in corrosive locations where a weather-resistant or non-metallic enclosure would be required. Also avoid applications where the available fault current exceeds the marked short-circuit rating or where project specifications call for a different enclosure type, trip function, or coordination study result.

        Best for

        Best for contractors, panel shops, and maintenance teams that want a factory-assembled enclosed breaker to reduce field assembly time. It is a practical choice for indoor commercial and industrial projects where a 400A disconnecting and overcurrent device is needed in one enclosure.

        Installed in

        Typically installed in electrical rooms, service areas, manufacturing facilities, commercial buildings, and indoor distribution spaces. Final mounting clearances, conductor sizing, and overcurrent coordination should follow the Canadian Electrical Code and the project design.

        Why this product exists

        This product exists to provide a ready-to-install enclosed breaker assembly instead of sourcing the breaker, enclosure, and wiring components separately. That can help reduce labour, simplify procurement, and improve consistency on panel-ready installations.

        Compared with similar products

        Compared with an open-style MCCB, this unit adds a factory enclosure for standalone mounting and safer operation in indoor spaces. Compared with larger fusible switches or higher-frame enclosed breakers, this 400A M3S assembly is commonly selected where a compact molded case solution meets the required ampacity and fault rating. As typical guidance only, 400A enclosed breakers are commonly used on larger feeders and equipment supplies; actual suitability depends on conductor sizing, available fault current, coordination, and local code.

        Actual performance depends on installation conditions, available fault current, conductor terminations, and local electrical code.
