Molded Case Circuit Breaker · 500A 3-Pole 65kA @ 480VAC · Lug Line/Load Side · Noark Electric M4N500T3L
SKU: M4N500T3L
500A 3-pole molded case circuit breaker with 65kA interrupting capacity at 480VAC, adjustable thermal/adjustable magnetic trip, and lug line/load side terminals. Suited for high-current distribution equipment, switchboards, and enclosure kit builds in Canadian commercial and industrial applications.
What this product is for
This molded case circuit breaker is used for overcurrent protection and switching in high-amperage commercial and industrial distribution systems. The M4N500T3L is a 500A, 3-pole breaker in Noark’s M4N frame with lug line/load side connections and a high interrupting rating for 480VAC systems.
Use for
Use for main or feeder protection in switchboards, panel assemblies, enclosed breaker kits, and large equipment disconnect applications where a 500A 3-pole MCCB is required. Commonly selected for 600VAC class systems with available fault current requiring up to 65kA interrupting capacity at 480VAC.
Avoid for
Avoid for applications requiring a different trip style, a 100% rated breaker, or accessories/configurations not included with this catalog number. Confirm enclosure compatibility, conductor range, and fault-duty requirements before ordering.
Best for
Best for electricians, panel builders, and maintenance teams needing a 500A MCCB with factory lug terminations and adjustable thermal/adjustable magnetic protection. It is a practical choice where line and load lugs are preferred to simplify field installation.
Installed in
Typically installed in commercial and industrial electrical rooms, service distribution equipment, OEM panels, and custom assemblies. This product is generally used in fixed equipment and enclosed distribution systems rather than branch-circuit device layouts.
Why this product exists
This breaker fills the need between smaller distribution breakers and larger power circuit protection by providing a 500A trip rating in a 600A frame size. For buyers comparing frame and trip combinations, this allows standardization on a larger frame while protecting a 500A circuit.
Compared with similar products
Compared with lower interrupting MCCBs, the M4N series provides higher fault-duty performance at 480VAC. Compared with breakers that require separate terminal ordering, this catalog number includes lug line/load side connection style, which can reduce parts matching during panel assembly. As a typical buying check, confirm the available fault current at the installation point and match it to the breaker interrupting rating. Actual suitability depends on system design, conductor selection, installation conditions, and local electrical code.
