ITE | HJ3B225 | Circuit Breaker | 3-Pole

The ITE HJ3B225 is a 3-pole circuit breaker built for three-phase panels that demand dependable overcurrent protection. This unit is intended for maintenance, retrofit, and replacement projects where exact compatibility matters, and the part number HJ3B225 serves as the primary reference to ensure a precise fit.

Why the 3-pole configuration matters: in three-phase electrical systems, a 3-pole breaker protects all three conductors together, maintaining coordinated disconnect and consistent protection across the circuit. Using the exact HJ3B225 reference helps preserve panel integrity, wiring layout, and protection coordination during upgrades or repairs.

• Poles: 3-Pole
• Part number: HJ3B225

Fitment and compatibility

Before ordering, verify that the breaker matches your panel’s requirements. The HJ3B225 part number is the most reliable indicator of compatibility, ensuring you receive the correct pole count, mounting footprint, and electrical characteristics for your installation. This is especially important for legacy or specialized panels where substitutions can lead to mismatched fit or unsafe operation.

Ideal use cases

• Maintenance and service on three-phase systems that require a like-for-like replacement
• Retrofit projects where upgrading protection while preserving panel design is necessary
• Replacement in older installations that originally used ITE components with the HJ3B225 designation

Practical tips to ensure a smooth replacement

• Cross-check your panel model, voltage rating, and current rating to ensure the HJ3B225 aligns with system requirements
• Keep the part number handy in maintenance records; it’s the quickest way to confirm a correct, compatible replacement
• If integrating into a mixed-brand panel, confirm mounting and terminal configurations to avoid compatibility issues
