JDB3100 - 100Amp Circuit Breaker

JDB3100 - 100Amp Circuit Breaker

If you're looking for a JDB3100, the breaker type and frame are just as important as the 100-amp rating. This Eaton Series C molded-case circuit breaker is a three-pole JDB model with a J frame and a T186 trip type, supplied as a complete breaker. The JDB3100 is built to last, but choosing the right replacement still comes down to compatibility. Check the JDB type, J frame, T186 trip, three-pole layout, electrical ratings, and physical dimensions against the breaker already installed and against the equipment requirements.

Key Features and Benefits

• 100A, three-pole design: A clear starting point for identifying the correct replacement.
• JDB breaker type: Helps narrow down compatibility when the existing equipment specifically calls for a JDB model.
• J frame: Provides another important form-and-fit identifier to check before installation.
• T186 trip type: Matches applications requiring this particular trip specification.
• Complete molded case circuit breaker: Supplied as a complete breaker rather than simply a frame or separate trip component.
• 600VAC / 250VDC rating: Supports equipment requiring the manufacturer's stated AC or DC voltage rating.
• UL Listed: Certification is clearly documented by the manufacturer.

Where It Works Best

The JDB3100 is best suited to compatible existing and legacy electrical equipment that calls for a 100A, three-pole Series C breaker with the JDB type, J frame, and T186 trip configuration. It's a particularly specific combination of characteristics that's useful when you're trying to identify a form, fit, and functional replacement rather than simply searching by amperage.
