KD3175 - 175Amp Circuit Breaker

KD3175 - 175Amp Circuit Breaker

The KD3175 is designed for applications where the breaker details must align closely with the equipment already in place. It's a 175-amp, three-pole Series C molded-case circuit breaker built on a K-frame and supplied as a complete breaker. If you're matching a breaker for existing or legacy equipment, compare the entire set of specifications rather than stopping at the 175A rating. When the KD3175 catalog number, frame, trip type, dimensions, terminals, and electrical ratings correspond with the application, it can provide the form, fit, and function the equipment requires.

Key Features and Benefits

• 175A, three-pole design: Suits equipment specifically requiring this amperage and pole arrangement.
• Complete breaker: The KD3175 is supplied as a complete molded case circuit breaker, not simply a breaker frame.
• Series C, Type KD configuration: Provides clear series, breaker type, and frame information for checking an existing installation.
• K frame: An important identification point when confirming physical and functional compatibility.
• 600VAC and 250VDC rating: Gives you the stated voltage ratings to compare with the requirements of the electrical system.
• T186 trip type: Another key detail to confirm when matching the breaker to existing equipment.
• Line and load terminals: Both are specified for this breaker, with aluminum terminal material.
• 50–60Hz operation: Matches applications requiring a frequency within this stated range.

Material Compliance and Certifications

The KD3175 is UL Listed, and the supplied specifications identify aluminum as the terminal material.

No specific RoHS, REACH, or other material-compliance information was provided, so those designations shouldn't be assumed. Where a particular certification or material requirement applies to the job, check the markings on the breaker and the applicable product and equipment documentation.

Where It Works Best

The KD3175 belongs in compatible electrical equipment that calls for this particular 175A, three-pole Type KD, K-frame configuration. It's especially relevant when maintaining legacy equipment where retaining the required breaker form, fit, ratings, and function is the priority.

There are several details worth checking before calling it a match. Confirm the KD3175 catalog number, T186 trip type, 175A rating, three-pole arrangement, K frame, and 600VAC/250VDC voltage rating. The interrupting capacity matters too: this breaker is rated at 35 kAIC at 480 VAC and 65 kAIC at 240 VAC.
