ALLEN BRADLEY 140U-JD6D3-D22

ALLEN BRADLEY 140U-JD6D3-D22 is a heavy-duty moulded case circuit breaker of Bulletin 140U series, 3-pole with 225A rated thermal-magnetic trip unit. The moulded case circuit breaker delivers high short-circuit breaking capacity for low voltage power distribution circuits. This moulded case circuit breaker provides overload and short-circuit protection for main power feeders and heavy motor loads. The moulded case circuit breaker adopts compact frame design to fit inside industrial and marine electrical control cabinets.

This breaker provides thermal magnetic overcurrent protection for power circuit safety isolation. The thermal magnetic overcurrent protection uses thermal element to respond to long-time overload conditions. The thermal magnetic overcurrent protection triggers instantaneous magnetic trip when short-circuit fault occurs. The thermal magnetic overcurrent protection protects cables, busbars and downstream electrical equipment from severe damage.

This ALLEN BRADLEY spare is an essential low voltage distribution spare for power panel maintenance and retrofit. The low voltage distribution spare can replace original 140U-J series breakers directly. The low voltage distribution spare meets IEC and UL international electrical standards. The low voltage distribution spare is widely applied in factory, petrochemical and marine onboard power control systems.

ALLEN BRADLEY 140U-JD6D3-D22 3-pole 225A MCCB belongs to discontinued 140U series. It integrates thermal-magnetic trip function, cuts off faulty circuits quickly under overload and short-circuit events, commonly used as main feeder protection for industrial and marine low voltage power distribution panels.
