CAH2175W - 175Amp Circuit Breaker

CAH2175W - 175Amp Circuit Breaker

If you've landed on the CAH2175W, there's a good chance you're trying to match a breaker that's already installed in your equipment. When that's the case, details matter. The CAH2175W is a 175 Amp, 2-pole molded case circuit breaker with a 22kA interrupting rating at 120/240VAC, built for systems that require a Type CAH breaker and a non-interchangeable trip unit.

One of the first things electricians and maintenance teams check when replacing a breaker is whether the ratings match the original unit. The CAH2175W delivers the same key specifications many existing systems were designed around, helping maintain consistency within compatible electrical distribution equipment. This model is supplied without lugs installed, making it important to confirm connection requirements before installation.

You'll often find breakers like the CAH2175W in facilities where electrical equipment has been operating reliably for years—manufacturing plants, warehouses, schools, office buildings, healthcare facilities, and municipal properties. In these environments, the goal is rarely to change the system. It's usually to keep it operating as intended by using components that match the original design. Built to last and rated for operation in ambient temperatures up to 40°C (104°F), the CAH2175W continues to be used in applications where compatibility is the priority.

Installation should be performed by qualified personnel and in accordance with applicable electrical codes, equipment specifications, and local regulations. Compatibility with the intended system should always be verified before installation.

Where It Works Best

The CAH2175W is commonly used in electrical distribution equipment requiring a 175 Amp, 2-pole Type CAH molded case circuit breaker rated 22kA at 120/240VAC.

Typical applications include:

• Manufacturing facilities
• Warehouses and distribution centers
• Commercial office buildings
• Schools and universities
• Healthcare facilities
• Municipal and government buildings
• Electrical distribution panels
• Switchboards
• Maintenance and repair projects involving compatible Type CAH equipment

For many maintenance professionals, replacing a breaker starts with finding the same ratings and configuration already in service. The CAH2175W is intended for applications where the breaker type, amperage, interrupting rating, and physical footprint need to remain consistent with existing equipment requirements.
