KDC3150 - 150Amp Circuit Breaker

KDC3150 - 150Amp Circuit Breaker

If you're tracking down a KDC3150, you're probably not looking for just any 150-amp breaker. You need the specifications to line up with the equipment already in service. The KDC3150 is a 150A, three-pole Series C molded case circuit breaker with a Type KDC configuration, K frame, and T186 trip type. That's especially important when you're maintaining legacy electrical systems, where two breakers can share the same amperage but differ in frame, trip type, dimensions, terminals, or interrupting capacity.

Key Features and Benefits

• 150A, three-pole configuration: A clear starting point when matching the KDC3150 to existing equipment.
• Series C Type KDC breaker: The breaker type and series provide important identification details beyond amperage alone.
• Complete breaker: The KDC3150 is specified as a complete molded case circuit breaker, not a frame-only component.
• K frame and T186 trip type: Two more details that help confirm whether you're looking at the correct breaker configuration.
• 600VAC and 250VDC rated: Makes the breaker's stated voltage ratings easy to check against the application's requirements.
• Line and load terminals: Both are specified, with aluminum identified as the terminal material.
• 50/60Hz operation: Provides another straightforward specification for verifying compatibility with existing equipment.

Where It Works Best

The KDC3150 is a good fit to consider when you're maintaining compatible existing or legacy electrical equipment that calls for this particular 150A, three-pole Series C Type KDC configuration.

Here's where it's worth slowing down and checking the details. Don't stop once you see "150A." Confirm the KDC3150 catalog number, K frame, T186 trip type, three-pole arrangement, and 600VAC/250VDC ratings. The interrupting capacity matters too: this breaker is rated at 100 kAIC at 480 VAC and 200 kAIC at 240 VAC.
