Molded Case Circuit Breaker · 100A · 3-Pole · 65kA at 480VAC · Line/Load Lugs · Noark Electric M1N100T3L
SKU: M1N100T3L
100A 3-pole molded case circuit breaker for enclosed breaker kits and distribution assemblies, with 65kA interrupting capacity at 480VAC and line/load side lug connections. Commonly used for feeders, panel upgrades, HVAC equipment and light industrial distribution where available fault current and enclosure compatibility must be confirmed.
What this product is for
This 100A, 3-pole molded case circuit breaker is used in enclosed breaker assemblies, feeder protection and commercial or light industrial power distribution systems. It is part of NOARK's M1N frame family with line and load side lug terminations for straightforward enclosure-kit integration.
Use for
Use for 3-phase distribution circuits, feeder protection, HVAC disconnecting means, machinery feeds and panel retrofit work where a 100A breaker with a 65kA interrupting rating at 480VAC is required. Suitable where UL 489 and CSA compliance is needed for North American installations.
Avoid for
Avoid using this breaker where the available fault current exceeds its interrupting rating, where a different frame or trip characteristic is required, or where enclosure, bus, or terminal compatibility has not been verified. Do not assume fit across all breaker kits without checking the exact NOARK enclosure or assembly listing.
Best for
Best for contractors, panel builders and maintenance teams needing a compact 150A frame breaker set at 100A with lug connections on both line and load sides. It fits applications where higher fault-duty performance is needed compared with lower-rated MCCBs in the same ampacity range.
Installed in
Typically installed in enclosed breaker kits, distribution equipment, commercial service areas, mechanical rooms, rooftop unit feeds, pump panels and light industrial electrical rooms. Final installation must follow the equipment listing, conductor sizing, torque requirements and applicable Canadian Electrical Code requirements.
Why this product exists
This breaker provides branch or feeder overcurrent protection in a compact MCCB format while offering a 65kA rating at 480VAC for applications with higher available fault current. The included line/load lugs simplify ordering where field terminations are required at both ends.
Compared with similar products
Compared with lower-duty breakers in the same frame family, the M1N version is selected when the system fault level requires 65kA at 480VAC rather than 35kA. Compared with higher-duty variants, it can be a practical choice when 65kA is sufficient and a 100A, 3-pole thermal-magnetic MCCB is needed. As a rule of thumb, breaker selection should match both ampacity and available fault current at the point of installation; actual suitability depends on the upstream system and equipment assembly rating.
