SQUARE D POWERPACT JJ250 JJA36250CA 3POLE 250A MCCB WITH AL250JD LUG KIT

Square D PowerPact JJ250 JJA36250CA is a heavy-duty 3-pole molded case circuit breaker (MCCB) rated 250A, compatible with 380‑440V AC power systems, equipped with AL250JD cable lug kit. This thermal magnetic circuit breaker provides dual overload and short-circuit protection for power distribution, large motor loads and industrial/ marine switchboard cabinets. This MCCB uses high-grade silver alloy contacts, withstands large motor inrush current, has built-in self-protection functions including overcurrent, overheat and short-circuit trip. It complies with UL489 and IEC60947 standards, widely used for industrial power panels and marine auxiliary power distribution systems.

This unit is a vital industrial & marine electrical spare part for control cabinet overhaul. The electrical spare part receives control signal from PLC for circuit make/break operation. The electrical spare part cuts off power supply automatically in case of overload or short circuit fault to protect downstream motors and equipment. The electrical spare part can replace faulty breaker to restore power distribution and safety protection.

It delivers reliable power distribution overcurrent & short circuit protection for industrial and marine power systems. The power distribution overcurrent & short circuit protection trips quickly to isolate fault circuit during short-circuit event. The power distribution overcurrent & short circuit protection protects pumps, fans and heavy machinery from electrical damage. The power distribution overcurrent & short circuit protection supports manual on/off operation and local status indication.

JJA36250CA breaker is mounted inside low voltage main switchboard compartment. It is original Square D (Schneider) spare part for industrial and marine power system maintenance.
