JB3225 - 225A Circuit Breaker

JB3225 - 225A Circuit Breaker

For an existing electrical system, getting the replacement details right matters. The JB3225 is a 225A, 3-pole Type JB circuit breaker with thermal-magnetic operation and a non-interchangeable trip unit. Its interrupting ratings are 14k AIC at 600VAC, 22k AIC at 480VAC, and 25k AIC at 240VAC, giving you clear values to compare with the installation's requirements. For maintenance work involving compatible existing or legacy equipment, the JB3225 is intended to provide the required form, fit, and function when its complete specifications match the application.

Key Features and Benefits

• 225A, 3-pole configuration for equipment requiring these exact electrical characteristics.
• Type JB designation helps identify compatibility when replacing an existing breaker.
• Thermal-magnetic operation provides the trip arrangement specified for this breaker.
• Uses a non-interchangeable trip unit, an important point to verify when matching the original installation.
• Load-side terminals are included so that this connection detail can be factored into the replacement check.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other material compliance or certification information was provided in the available JB3225 specifications. These certifications should not be assumed from the Type JB designation, electrical ratings, or other product characteristics.

Where It Works Best

The JB3225 is best considered for compatible existing and legacy equipment that calls for a 225A, 3-pole Type JB thermal-magnetic circuit breaker with a non-interchangeable trip unit. It is particularly relevant when the goal is to maintain the original form, fit, and function rather than change the equipment configuration.
