JA3225W - 225Amp Circuit Breaker

JA3225W - 225Amp Circuit Breaker

Finding a replacement breaker for older equipment often comes down to the details. JA3225W is a 225A, 3-pole Type JA circuit breaker with thermal-magnetic operation and a non-interchangeable trip unit. For existing or legacy equipment that calls for this particular Type JA configuration, these specifications provide the information needed to verify form, fit, and function against the breaker being replaced. These products are built to last, but the correct replacement should always be selected by matching your equipment's complete electrical and physical requirements.

Key Features and Benefits

• 225A capacity: Intended for equipment requiring a 225-amp breaker rating.
• Three-pole: Matches installations requiring a 3-pole breaker configuration.
• Type JA: An essential identifier when checking compatibility with existing equipment.
• Thermal-magnetic operation: Uses the specified thermal-magnetic trip design.
• Non-interchangeable trip unit: Helps narrow down the correct configuration when matching an existing breaker.
• No terminals included: This JA3225W configuration is supplied without terminals; terminal requirements must be checked separately.

Material Compliance and Certifications

Specific UL, CSA, IEC, RoHS, REACH, or other certification and material-compliance information was not provided for the JA3225W. Those certifications should not be assumed from the breaker type, amperage, or voltage ratings.

Where It Works Best

The JA3225W 225A circuit breaker is best considered when maintaining compatible existing or legacy equipment that requires a 3-pole Type JA breaker with the same thermal-magnetic operation, non-interchangeable trip configuration, physical dimensions, and electrical ratings.
