Eaton JDB3250W Three-Phase Molded Case Circuit Breaker

Eaton JDB3250W is a three-phase molded-case circuit breaker designed to protect electrical circuits in industrial power systems from overloads and short circuits. Rated for 250 amps and up to 600 volts, this three-pole device interrupts fault currents across all three phases to help prevent damage to wiring and equipment in distribution panels, switchgear, and other protection schemes. The JDB3250W's molded-case construction provides robust mechanical integrity suitable for demanding environments, while its compact form factor helps maximize panel space in electrical assemblies. The three-pole configuration ensures simultaneous disconnection of all phases, improving safety and fault isolation in three-phase installations. Use of this unit supports establishing reliable protection for feeders and loads in industrial applications where a dedicated MCCB with a 250 A rating is required.
