JDC3125 - 125Amp Circuit Breaker

JDC3125 - 125Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, 125 amps and three poles only tell part of the story. The JDC3125 has several other details worth checking before you settle on the part: it's an Eaton Series C molded case circuit breaker with a JDC breaker type, J frame, and T186 trip type, supplied as a complete breaker. It also comes with aluminum terminals on both the line and load sides, so you know exactly what terminal arrangement is included. The JDC3125 is built to last, with clearly documented specifications that make a careful form, fit, and functional replacement check easier.

Key Features and Benefits

• 125A, three-pole breaker: A clearly defined configuration for equipment requiring this specific amperage and pole count.
• JDC breaker type and J frame: Two important identifiers to check when matching the breaker to existing electrical equipment.
• T186 trip type: Gives you another concrete specification to compare with the breaker already in place.
• Line and load terminals included: Aluminum terminals are provided on both sides, making the supplied connection arrangement clear.
• 600VAC and 250VDC ratings: Supports compatibility checks for equipment operating within the manufacturer's stated ratings.
