JDB3250 - 250A Circuit Breaker Description
JDB3250 - 250A Circuit Breaker
For the JDB3250, the electrical ratings provide a useful starting point for confirming your replacement: 250A, three-pole, 600VAC/250VDC, 65 kAIC at 240VAC, and 35 kAIC at 480VAC. This Eaton Series C molded-case circuit breaker uses a J frame, JDB breaker type, and T186 trip type, and is supplied as a complete breaker. Aluminum terminals are included on both the line and load sides, an important detail when comparing the connection arrangement with equipment already in service. The JDB3250 is built to last, while selecting it for existing or legacy equipment still comes down to a careful form, fit, and functional comparison of the complete specification set.

Where It Works Best
The JDB3250 250A circuit breaker is suited to compatible existing and legacy electrical equipment that specifically requires a three-pole Series C JDB breaker with a J frame and T186 trip type. Because this model includes aluminum terminals on both the line and load sides, the existing conductor and termination requirements should be checked during the compatibility review.
