Molded Case Circuit Breaker · 500A, 3-Pole, 600A Frame, 42kA @ 480VAC, Line/Load Lugs · Noark Electric M4S500T3L
SKU: M4S500T3L
500A 3-pole molded case circuit breaker with a 600A frame, thermal-magnetic trip unit, and line/load side lugs for feed-through installation. Rated 42kA at 480VAC, 65kA at 240VAC, and 22kA at 600VAC for commercial and industrial distribution equipment in Canada.
What this product is for
This molded case circuit breaker is used for overcurrent protection and switching in commercial and industrial power distribution systems. It is a 500A, 3-pole breaker in Noark’s M4S 600A frame series with factory-installed line and load side lugs.
Use for
Use for panelboards, switchboards, enclosure kits, and distribution assemblies where a 500A 3-pole UL 489 breaker is required. Suitable where available fault current and voltage ratings match the breaker’s interrupting capacity and application requirements.
Avoid for
Avoid using where a different interrupting rating, pole configuration, trip characteristic, or connection style is required. Do not select this breaker as a substitute for a fully adjustable electronic-trip breaker when the project calls for advanced protection settings or coordination features.
Best for
Best for contractors, panel builders, and maintenance teams needing a 500A MCCB with lug terminations on both line and load sides for faster enclosure or distribution equipment assembly. Commonly used in larger commercial services, industrial feeders, and equipment distribution sections.
Installed in
Typically installed in electrical rooms, service equipment, industrial control assemblies, and enclosed breaker systems. As a rule of thumb, 500A 3-phase breakers are commonly used on large feeders and distribution sections where conductor sizing, available fault current, and coordination have already been engineered. Actual application depends on equipment design, conductor terminations, ambient conditions, and local electrical code.
Why this product exists
This breaker provides branch, feeder, or equipment protection in higher-amperage systems without moving to a larger frame than necessary. The 600A frame allows a 500A trip rating within the M4S family, helping standardize enclosure and accessory selection across similar builds.
Compared with similar products
Compared with lower-frame MCCBs, this model supports higher ampacity applications and higher available fault current ratings within the M4S series. Compared with breakers that require separate terminal ordering, this version includes line and load side lugs, which can simplify material planning and installation.
