JB3225W - 225A Circuit Breaker

JB3225W - 225A Circuit Breaker

Getting the right replacement breaker means checking more than the amp rating. The JB3225W is a 225A, 3-pole Type JB circuit breaker with thermal-magnetic operation and a non-interchangeable trip unit. The JB3225W does not come with terminals, so terminal compatibility must be confirmed separately before installation. If your equipment calls for this Type JB configuration, the JB3225W offers a clearly specified option to maintain the required form, fit, and function. It's built to last and, just as importantly, provides the key ratings you need to check compatibility before putting it into service.

Key Features and Benefits

• 225-amp, 3-pole configuration for equipment requiring these specific electrical characteristics.
• Type JB circuit breaker for matching compatible existing and legacy installations.
• Thermal-magnetic operation with a non-interchangeable trip unit.
• 40°C rated according to the supplied specifications.
• Terminals are not included, an important point to account for when planning the replacement.
• Clearly defined ratings help maintenance teams verify the breaker against existing system requirements without relying solely on amperage.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other compliance certifications were provided in the available specifications for the JB3225W. These should not be assumed from the breaker type, voltage, or AIC ratings.

Where It Works Best

The JB3225W is best considered for compatible existing and legacy equipment that calls for a 225A, 3-pole Type JB breaker with thermal-magnetic operation and a non-interchangeable trip unit. It can be especially useful in replacement work where maintaining the original electrical ratings and physical footprint matters.
