Enclosed Circuit Breaker · 600A, 3-Pole 4-Wire, 600V AC, 100kA@480V, NEMA 1 Indoor · 100% Neutral Protection · Noark Electrical E01-4BM4H600T3L
What this product is for
This enclosed circuit breaker assembly is used for overcurrent protection and disconnecting in commercial and industrial power distribution systems where a factory-assembled 600A breaker in an indoor enclosure is required. It combines a Noark Ex9M4 series MCCB with a NEMA 1 steel enclosure for indoor service.
Use for
Use for feeder protection, service disconnects, distribution sections, equipment isolation, and other high-current indoor applications requiring a 3-pole, 4-wire assembly with neutral terminal provision. Commonly used where available fault current is high and a 100kA at 480V interrupting rating is needed.
Avoid for
Avoid using this enclosure outdoors, in washdown areas, or in dusty or corrosive locations where a NEMA 3R or NEMA 12 enclosure would be more appropriate. Do not select it where project requirements call for a different SCCR, enclosure type, or electronic trip functionality.
Best for
Best for electricians, panel builders, and maintenance teams needing a pre-assembled enclosed breaker that reduces field assembly time and helps standardize installations in indoor commercial and industrial facilities.
Installed in
Typically installed in electrical rooms, service areas, mechanical rooms, manufacturing facilities, and commercial buildings. The internal MCCB is approximately 12.3 in x 7.7 in x 5.4 in (313 x 195 x 138 mm); allow additional wall and working clearance based on the enclosure dimensions and local code requirements.
Why this product exists
This product provides a ready-to-install enclosed breaker solution for higher-current systems, combining breaker protection, enclosure, and 4-wire neutral provision in one assembly. It is intended to simplify procurement and installation compared with sourcing the breaker and enclosure separately.
Compared with similar products
Compared with 3-wire enclosed breakers, this 3-pole 4-wire version includes neutral provision for systems that require it. Compared with lower-interrupting models in the same family, the M4H configuration is selected where higher available fault current makes a 100kA at 480V rating necessary. As typical guidance, higher interrupting ratings are commonly chosen for larger service and feeder locations, but final selection must match the available fault current study and local electrical code.
Actual suitability depends on system voltage, available fault current, conductor terminations, enclosure environment, and installation conditions.
