KDC3100 - 100Amp Circuit Breaker

KDC3100 - 100Amp Circuit Breaker

There's a reason technicians check more than the 100A rating when they're tracking down a KDC3100. This three-pole Series C molded-case circuit breaker is a Type KDC complete breaker built on a K frame, with a specific combination of electrical ratings and physical dimensions that must agree with the equipment already in service. For electricians and maintenance teams working with existing or legacy equipment, these details provide a straightforward way to verify whether your breaker is appropriate for the application.

Key Features and Benefits

• 100A, three-pole configuration: A clearly defined rating and pole arrangement for equipment that specifically calls for this setup.
• Complete breaker: The KDC3100 is supplied as a complete molded case circuit breaker, not simply a breaker frame.
• Series C, Type KDC: Makes it easier to identify the correct breaker family when checking an existing installation.
• T186 trip type: Provides another specific identification point when comparing the KDC3100 with the existing breaker.
• 600VAC and 250VDC rated: Both voltage ratings are clearly specified to match the application.
• Line and load terminals: Both are specified in the breaker configuration.
• 50/60Hz operation: Gives you another electrical characteristic to verify against the equipment requirements.
• UL Listed: The supplied product specifications indicate that the KDC3100 is UL Listed.

Where It Works Best

The KDC3100 is a good fit for maintaining compatible existing or legacy equipment that calls for a 100A, three-pole Series C Type KDC breaker with a K frame and T186 trip type.

On a replacement job, work through the specifications one by one. The electrical system needs to correspond with the breaker's 600VAC/250VDC ratings and its required interrupting capacity. At 480VAC, the KDC3100 is rated 100 kAIC; at 240VAC, it is rated 200 kAIC.
