JDB3150W - 150Amp Circuit Breaker

JDB3150W - 150Amp Circuit Breaker

At 12.3 inches in length/depth, 6.8 inches wide, and 6.2 inches high, the JDB3150W has a defined footprint that can be checked directly against the breaker being replaced. This Eaton Series C molded-case circuit breaker is rated at 150A, has three poles, and is identified as a JDB type with a J frame and a T186 trip type. The JDB3150W is built to last, and for your existing or legacy equipment, the key is a careful spec-for-spec check rather than relying on amperage alone.

Key Features and Benefits

• 150A, three-pole configuration for equipment that specifically calls for these ratings.
• JDB breaker type and J frame provide two important identifiers when checking an existing installation.
• T186 trip type gives you another specific point to compare with the breaker being replaced.
• Complete breaker configuration as identified in the manufacturer specifications.
• Supplied without terminals, so there is no guesswork about whether terminals are included.
• 600 VAC and 250 VDC voltage ratings provide clear electrical compatibility information.
• 50/60 Hz frequency rating should be checked against the electrical system requirements.
• UL Listed according to the manufacturer.
