The NORM2N175T3L NOARK MCCB offers exceptional protection with a 250 A frame size and a short-circuit interruption rating of 100 kA at 240 Vac. Designed for 175A applications, this 3-pole circuit breaker features lug connections on both line and load sides, ensuring reliable performance and enhanced safety in diverse electrical systems.
As a 250 A frame, bolt-on MCCB, the NORM2N175T3L is designed for industrial and commercial panelboards and switchboards that accept bolt-on MCCBs of this frame size — not residential loadcentres. Compatibility depends on the bus stab spacing and mounting rails of your specific enclosure. Contact our team with your panelboard model and we'll confirm compatibility.
Lug terminations on both the line and load sides mean this breaker uses set-screw or mechanical lugs rather than bus-stab connections for both incoming and outgoing conductors. This is common in main-breaker or feeder applications. Exact conductor range (AWG/kcmil) is specified in the Noark M2N product datasheet — reach out to us and we can provide the full termination spec for your installation.
Noark's M2N series is an actively manufactured line, but availability in Canada can be limited through standard distribution channels. Northern Breaker Group specializes in sourcing both current and hard-to-find MCCBs, including Noark.
