JL3B225 - 225Amp Circuit Breaker

JL3B225 - 225Amp Circuit Breaker

The JL3B225 has a published footprint of 9.00 inches wide, 11.00 inches long, and 4.00 inches deep, giving you concrete dimensions to compare with the breaker and equipment already in place. The JL3B225 is built to last, while its clearly defined frame, dimensions, pole count, current rating, and voltage-specific AIC ratings provide the information needed to evaluate form, fit, and functional compatibility with existing and legacy electrical equipment.

Key Features and Benefits

• 225A current rating provides a clear starting point for matching the breaker to the electrical requirements of existing equipment.
• Three-pole configuration allows direct comparison with the breaker being replaced.
• JL3 frame type is an important physical and compatibility identifier.
• Supplied identification includes Type ET, 400 Ampere "JL" Frame.
• 40°C rated according to the provided specifications.

Material Compliance and Certifications

Specific UL, CSA, IEC, RoHS, REACH, or other certification and material-compliance information was not included in the supplied JL3B225 specifications. These certifications should not be assumed. When a particular standard or approval is required, confirm it from the product labeling and applicable technical documentation before installation.

Where It Works Best

The JL3B225 is suited to compatible existing and legacy electrical equipment requiring a 225A, three-pole molded case circuit breaker with a JL3 frame and the corresponding interrupting rating for the system voltage. The published dimensions are particularly useful when checking the physical space and form of an existing installation.

Before installation, compare the complete specifications—not just the 225A rating. Confirm the JL3 frame, pole count, dimensions, system voltage, required AIC rating, and other equipment requirements against the breaker being replaced. That practical compatibility check helps ensure the JL3B225 is appropriate for the intended installation.
