JDB3250W - 250Amp Circuit Breaker

JDB3250W - 250Amp Circuit Breaker

At 250 amps, the JDB3250W sits within a very specific set of replacement requirements: three poles, a J frame, JDB breaker type, T186 trip type, and no terminals supplied. Eaton identifies this Series C molded case circuit breaker as a complete breaker, so the “without terminals” specification is especially important to account for when checking the connection arrangement in your existing equipment. The JDB3250W is built to last, but proper replacement selection still depends on ensuring that its frame, trip type, electrical ratings, dimensions, and terminal requirements match those of the equipment already in service.

Key Features and Benefits

• The 250A, three-pole configuration provides the core rating information needed to identify a compatible replacement.
• The JDB breaker type and J frame provide specific identifiers for comparing with the existing breaker and equipment.
• T186 trip type helps further confirm the required breaker configuration.
• Supplied as a complete Series C molded case circuit breaker.
• Terminals are not included, allowing that requirement to be identified separately when checking the existing termination arrangement.
• Rated for 600VAC and 250VDC at 50–60 Hz.

Where It Works Best

The JDB3250W 250A circuit breaker is suited to compatible existing and legacy electrical equipment that specifically calls for a three-pole Series C JDB breaker with a J frame, T186 trip type, and the corresponding electrical and physical characteristics. It is particularly important to recognize the “without terminals” configuration when comparing this catalog number with the breaker being replaced.
