JA3225 - 225Amp Circuit Breaker

JA3225 - 225Amp Circuit Breaker

Replacing a breaker in older equipment usually comes down to one thing: do all the specifications match? The JA3225 is a 225-amp, 3-pole Type JA circuit breaker with thermal-magnetic operation and a non-interchangeable trip unit. This particular version also comes with load-side terminals included, which is worth confirming when comparing it with the breaker already in place. At 5.50"W x 10.13"L x 3.94"D, its dimensions give you another important checkpoint before installation. For existing or legacy equipment that requires this specific Type JA configuration, the JA3225 offers the form, fit, and function needed for a properly matched replacement.

Key Features and Benefits

• 225A rating for equipment specifically calling for a 225-amp breaker.
• Three poles make it easy to compare the configuration with the existing breaker.
• Type JA designation helps narrow down the correct replacement for compatible equipment.
• Uses thermal-magnetic operation with a non-interchangeable trip unit.
• Load-side terminals are included, an important detail when checking replacement requirements.
• 40°C rated for applications requiring this temperature specification.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided in the available specifications for the JA3225. Those certifications should not be assumed from the breaker type or ratings. If a particular listing or compliance standard is required, check the markings on the breaker and the applicable manufacturer documentation before installation.

Where It Works Best

The JA3225 is suited to compatible existing and legacy equipment that calls for a 225A, 3-pole Type JA breaker with thermal-magnetic operation and a non-interchangeable trip unit. Since this model includes load-side terminals, that detail should also match the requirements of the equipment being serviced.
