KDC3175 - 175Amp Circuit Breaker

KDC3175 - 175Amp Circuit Breaker

A breaker search gets much easier once you move past amperage and look at the specifications that actually identify the part. The KDC3175 is a 175-amp, three-pole Series C molded-case circuit breaker with a K frame and a T186 trip type, supplied as a complete breaker. For maintenance teams working with existing electrical equipment, the physical details are just as useful: the KDC3175 measures 5.5 inches wide, 5.5 inches high, and 4.1 inches deep. Put those specifications together, and you have a much clearer way to determine whether this is the breaker your application calls for.

Key Features and Benefits

• 175A, three-pole configuration: Clearly identifies the breaker's amperage and pole arrangement for compatibility checks.
• Series C Type KDC: Gives electricians and maintenance personnel specific series and breaker-type information to compare with existing equipment.
• Complete breaker configuration: The KDC3175 is specified as a complete molded-case circuit breaker, not a frame-only component.
• T186 trip type: Provides another specific point to verify against the existing breaker and equipment documentation.
• 600 VAC and 250 VDC ratings: Specify the breaker's stated AC and DC voltage ratings.
• Aluminum line and load terminals: Terminal location and material are clearly identified, helping with a more complete compatibility check.
• 50 to 60Hz frequency rating: Makes it straightforward to compare the breaker's frequency specification with the application.

Material Compliance and Certifications

The KDC3175 is UL Listed, according to the supplied manufacturer specifications. Its line and load terminals are identified as aluminum, giving maintenance personnel another documented material detail to consider when checking the breaker against application requirements.

Where It Works Best

The KDC3175 is best considered for compatible existing and legacy electrical equipment that specifically requires a 175A, three-pole Type KDC Series C molded case circuit breaker with the corresponding K-frame configuration.

When you're identifying a replacement breaker, start with the catalog number—but keep going. Confirm the 175A rating, three poles, K-frame, T186 trip type, 600VAC/250VDC voltage ratings, and 50–60Hz frequency rating against the requirements of the equipment.
