Molded Case Circuit Breaker · 250A, 3-Pole, 35kA @ 480Vac · Line/Load Lugs · Noark Electric M2S250T3L
SKU: M2S250T3L
250A 3-pole molded case circuit breaker for enclosed breaker kits and distribution equipment, with 35kA interrupting capacity at 480Vac and line/load side lugs. Commonly used for feeder and main distribution protection in commercial and industrial assemblies; verify available fault current, conductor range, and enclosure compatibility before ordering.
What this product is for
This molded case circuit breaker is used for overcurrent and short-circuit protection in commercial and industrial power distribution equipment. The Noark M2S250T3L is a 250A, 3-pole breaker in the M2S series with line and load side lugs for enclosed breaker kits and similar assemblies.
Use for
Use for 600Vac class distribution systems where a 250A thermal-magnetic MCCB is required, including feeder protection, service distribution sections, panel assemblies, and enclosed breaker applications. It is typically selected where 35kA interrupting capacity at 480Vac matches the available fault current at the installation point.
Avoid for
Avoid using this breaker where the available fault current exceeds the breaker interrupting rating, where a different trip characteristic is required, or where the enclosure kit or conductor terminations do not match the breaker. Do not assume suitability for every panelboard or switchgear lineup without confirming the manufacturer’s approved mounting and accessory requirements.
Best for
Best for electricians and panel builders needing a 250A frame MCCB with 3-pole protection and factory lug terminations on both line and load sides. It suits commercial buildings, light industrial distribution, and retrofit enclosed breaker assemblies where a straightforward lug-in/lug-out connection is preferred.
Installed in
Typically installed in enclosed circuit breaker kits, distribution sections, control panels, and other approved power distribution equipment. Actual installation method depends on the enclosure system, conductor size, torque requirements, and local electrical code.
Why this product exists
This breaker provides branch, feeder, or main protection in applications that need a compact MCCB format rather than a fusible switch or larger power breaker. The included line/load lugs simplify selection for assemblies that require direct cable termination.
Compared with similar products
Compared with lower-amp M2S models in the same 250A frame family, this version is the full 250A rating. Compared with higher interrupting MCCBs, this model should be chosen when 35kA at 480Vac is sufficient for the available fault level. As a typical trade rule, breaker selection should also consider continuous loading at no more than 80% unless the equipment and application are specifically rated otherwise. Actual application depends on code, ambient conditions, and equipment listing.
