JDB3100W - 100Amp Circuit Breaker

JDB3100W - 100Amp Circuit Breaker

The JDB3100W has one detail worth checking early: it is supplied without terminals. That matters when you're matching a breaker to an existing assembly and need the replacement part to align with the existing connection requirements. The JDB3100W is built to last and is well suited to form, fit, and functional replacement work where this exact combination of frame, ratings, dimensions, trip type, and terminal configuration is required.

Key Features and Benefits

• 100A, three-pole configuration: Provides the specific amperage and pole count needed when replacing a matching breaker.
• JDB breaker type with J frame: Two useful identifiers for confirming compatibility with existing or legacy electrical equipment.
• Supplied without terminals: Important to know before installation so the required terminal arrangement can be checked separately.
• T186 trip type: Helps confirm that the trip configuration corresponds with the equipment requirements.
• 600VAC and 250VDC rating: Clearly defines the manufacturer's stated AC and DC voltage ratings.
• Complete breaker: Manufacturer specifications identify the JDB3100W as a complete molded case circuit breaker.
• UL Listed: The product carries the manufacturer's stated UL certification.

Where It Works Best

The JDB3100W is suited to compatible existing and legacy electrical equipment that specifically calls for a 100A, three-pole JDB breaker with a J frame, T186 trip type, and no supplied terminals. The terminal configuration is especially important here; the "W" model should be matched according to the connection requirements of the existing equipment rather than treated as interchangeable with configurations supplied with terminals.
