Description
The PowerPact™ J-frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits. J-frame circuit breakers are available with either thermal-magnetic or Micrologic™ electronic trip units. The amperage ratings of the thermal trip elements are calibrated at 104°F (40°C) free air ambient temperature. Per the National Electric Code® (NEC®) and the Canadian Electrical Code, standard circuit breakers may only be applied continuously at up to 80% of their rating. This PowerPact J, circuit breaker and is 3-pole and has a breaking capacity of 65kA@240VAC and has a rated current of 250A. This ia a unit mount breaker and complies to UL listed, IEC, CCC, CE & CSA standards. With an electrinic trip unit it has an LI function and an ABC Phase Connectiion. Dimensions for this product are 7.52 in (H),4.12 in (W), 5 in (D) with an ambient temperature rating of 50 °C. This product comes with an 18 month warranty.
Features
- This Square D PowerPacT J-frame molded case circuit breaker (MCCB) handles a continuous current rating of 250 Amps at up to 600VAC, making it the ideal high-capacity choice for demanding industrial and commercial electrical distribution setups. Its standard 3-pole design easily integrates into your main panel disconnect or control panel configurations, ensuring heavy-duty performance where space and reliability matter.
- Equipped with the state-of-the-art MicroLogic 3.2S trip unit, this breaker offers highly accurate LSI (Long-time, Short-time, and Instantaneous) solid-state overcurrent protection. This advanced electronic monitoring allows you to fine-tune your selective coordination, minimizing unnecessary downtime by isolating faults precisely where they occur while protecting downstream infrastructure from severe overloads.
- Engineered with a G interrupting rating code, this breaker delivers a robust breaking capacity of 35kA at 480VAC and 18kA at 600VAC. This high-fault threshold ensures rapid energy suppression via dual-break rotating contacts that actively minimize peak current during a fault, shielding your critical commercial machinery from devastating thermal and mechanical stress.
- this specific model boasts a true 100% continuous current rating. This allows electrical engineers to design systems to maximum capacity without built-in safety margins, reducing overall panel space requirements and slashing installation material costs.
- Ready for unit-mount deployment, this circuit breaker comes fully complete with mechanical line and load-side lugs (AL250JD terminal identifiers) accommodating AWG 3/0 to 350 kcmil aluminum or copper wiring. The convenient feed-thru connection and standard J-frame mounting hole spacing streamline retrofits and speed up field installation time.
- Built for worry-free global and local acceptance, this unit is fully UL 489 listed, CSA certified, NEMA compliant, and CE marked. It features an IP40 front cover degree of protection and explicit suitability for isolation, guaranteeing absolute compliance with the highest safety regulations for commercial contractors and facility managers alike.
