JJ3B225 - 225Amp Circuit Breaker

JJ3B225 - 225Amp Circuit Breaker

The JJ3B225 has a clearly defined footprint—9.00 inches wide, 11.00 inches long, and 4.00 inches deep—which is useful when you're checking physical fit in existing electrical equipment. The JJ3B225 is built to last and is a practical replacement option when its frame, dimensions, pole count, current rating, and interrupting capacity correspond with the requirements of the equipment already in service.

Key Features and Benefits

• 225A current rating: Provides a clearly defined amperage for matching compatible existing equipment.
• Three-pole configuration: Makes pole-count verification straightforward when selecting replacements.
• JJ3 frame: Provides an important identifier when checking physical and functional compatibility.
• Type ET identification: Specifications identify the unit as a Type ET, 400 Ampere "JJ" frame molded-case circuit breaker.
• 40°C rating: Another useful specification to verify against the existing installation.

Material Compliance and Certifications

Specific UL, CSA, IEC, RoHS, REACH, or other material-compliance and certification information was not included in the supplied JJ3B225 specifications. No certification should be assumed from the frame type or electrical ratings alone. Where a particular approval or compliance standard is required, verify it against the product labeling or applicable manufacturer documentation.

Where It Works Best

The JJ3B225 is suited to compatible existing and legacy electrical equipment requiring a 225A, three-pole molded case circuit breaker with the corresponding JJ3 frame characteristics. Its defined dimensions and separate AIC ratings at 240VAC, 480VAC, and 600VAC make it easier to compare the part with the electrical and physical requirements of an existing installation.
