JJ3B175 - 175Amp Circuit Breaker

JJ3B175 - 175Amp Circuit Breaker

The JJ3B175 gives you several concrete identifiers to work from when sourcing a breaker for existing electrical equipment. Rated at 175 amps with three poles, this molded case circuit breaker uses a JJ3 frame and is further identified as a Type ET, 400 Ampere “JJ” Frame unit. The JJ3B175 is built to last and is intended for form, fit, and functional replacement where these electrical ratings, frame characteristics, dimensions, and other specifications correspond with the equipment already in service.

Key Features and Benefits

• 175A, 3-pole configuration: Provides clear current and pole-count specifications for replacement matching.
• JJ3 frame type: An important identifier when checking compatibility with existing equipment.
• Type ET “JJ” Frame: Listed as a 400 Ampere “JJ” Frame in the available product specifications.
• Molded case construction: Matches the specified circuit breaker type for this catalog number.
• 40°C rated: Another specification to confirm against the requirements of the existing installation.

Material Compliance and Certifications

Specific UL, CSA, IEC, RoHS, REACH, or other compliance certifications were not included in the supplied JJ3B175 product data. They should not be assumed from the frame type or electrical ratings alone. Where a particular approval or material-compliance requirement applies, confirm it from the breaker labeling or applicable manufacturer documentation.

Where It Works Best

The JJ3B175 is suited to compatible existing and legacy electrical equipment that calls for a 175A, three-pole molded case circuit breaker with matching JJ3 frame characteristics. The combination of frame identification, physical dimensions, and voltage-specific AIC ratings makes this model particularly straightforward to compare with an existing breaker.
