KA3175 - 175Amp Circuit Breaker

KA3175 - 175Amp Circuit Breaker

When you're trying to identify the right 175A replacement breaker, the KA3175 gives you several concrete details to check against the unit already installed. It's a three-pole Type KA circuit breaker with a thermal-magnetic design, an interchangeable trip unit, and load-side terminals. The KA3175 is built to last, while keeping the focus where it belongs for legacy replacement work—matching the required amperage, pole count, Type KA configuration, trip-unit arrangement, electrical ratings, terminals, and physical footprint.

Key Features and Benefits

• 175A, three-pole configuration provides clear electrical identifiers for replacement matching.
• Type KA circuit breaker for compatible equipment calling for this specific breaker type.
• Uses a thermal-magnetic trip design with an interchangeable trip unit.
• Load-side terminals are included, an important connection detail to verify against the existing installation.
• 40°C rated to match installations requiring this specified temperature rating.
• Well suited to form, fit, and functional replacement in compatible existing and legacy electrical equipment.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other material-compliance or certification information was included in the supplied KA3175 specifications. These approvals should not be assumed. For installations governed by a particular standard or certification requirement, confirm the applicable product documentation before use.

Where It Works Best

The KA3175 175A 3-pole circuit breaker is best considered for compatible existing and legacy electrical equipment that specifically requires a Type KA, 175A thermal-magnetic breaker with an interchangeable trip unit. Its documented interrupting ratings, load-side terminals, 40°C rating, and published dimensions give you useful checkpoints when evaluating a replacement.

Before installation, compare the complete specifications with the breaker being replaced. In particular, verify the KA3175 part number, Type KA designation, 175A rating, three-pole arrangement, trip-unit design, A.I.C. ratings, terminal configuration, temperature rating, and physical dimensions. Matching those details is the practical way to determine whether the KA3175 provides the required form, fit, and function for the equipment already in service.
