Circuit Breaker Enclosure · 400A 600V · NEMA 1 Indoor for M3 Frame 300-400A Breakers · Noark Electrical X400-600TYPE 1
What this product is for
This NEMA 1 enclosed breaker housing is used to mount a 400A, 600V Noark M3-frame molded case circuit breaker assembly in an indoor location. It is intended for independent mounting of feeder or branch circuit protection where basic contact protection is required.
Use for
Use for indoor electrical rooms, service areas, commercial buildings, and light industrial installations where a breaker must be mounted separately from switchboards or panelboards. Suitable for applications aligned with enclosed breaker assemblies using Noark M-Series M3 frame devices in the 300A to 400A range.
Avoid for
Avoid outdoor, washdown, dusty process, or wet locations. For those environments, a Type 3R or Type 12 enclosure is typically the better choice. This enclosure is not the breaker itself and should not be ordered as a complete protective device unless the matching internal breaker assembly is also specified.
Best for
Best for contractors and panel builders needing an indoor 400A enclosed breaker solution with a Noark M3 frame footprint. It is a practical choice when the project calls for a separately mounted breaker enclosure rather than a full distribution assembly.
Installed in
Typically installed on indoor wall-mounted electrical infrastructure in commercial and industrial spaces. Common installations include service rooms, mechanical rooms, utility areas, and production spaces with normal indoor conditions.
Why this product exists
This enclosure provides the housing required for a compliant enclosed breaker assembly using Noark M-Series breakers. It helps protect personnel from incidental contact with live components while providing a dedicated mounting platform for feeder or branch circuit protection.
Compared with similar products
Compared with Type 3R enclosures, this Type 1 version is intended for indoor use only and is generally chosen where weather protection is not required. Compared with Type 12, it is better suited to clean, dry indoor spaces rather than dusty industrial environments. For buyers selecting by breaker frame, this model matches the Noark M3 frame, commonly used for approximately 300A to 400A breaker applications.
Typical guidance only: actual assembly suitability depends on the selected breaker, terminals, installation method, and local electrical code.
