Cutler-Hammer JDB3070W Molded Case Circuit Breaker

Cutler-Hammer JDB3070W molded case circuit breaker is a 70 A, 600 V, three-pole protection device designed to interrupt fault current and protect electrical circuits. As a Cutler-Hammer component within the Cutler-Hammer family, this MCCB uses molded-case construction that supports reliable isolation of faulted circuits in three-phase power systems. The JDB3070W is rated for 70 amperes and 600 volts, providing overcurrent protection for feeders and equipment that operate within that voltage class by opening the circuit when overloads or short circuits occur. Its three-pole configuration ensures all three conductors in a 3-phase installation are interrupted simultaneously, which helps maintain balanced protection across phases. This part is suitable for applications requiring a dedicated MCCB with a 70 A rating at 600 V in a three-phase setup and is identifiable by the JDB3070W model name within the Cutler-Hammer line. The 3-pole design aligns with typical three-phase distribution schemes.
