Fitment, compatibility, and selection tips

Before ordering, verify that the BL370 matches your system’s ratings and mounting scheme. The part number is your best reference for compatibility, so use it to confirm frame fit, pole configuration, and bolt-on mounting alignment with your panel. If in doubt, cross-check with the panel manufacturer’s documentation to ensure voltage, current rating, and trip characteristics align with your protection requirements.

Installation notes

Ensure the power is safely isolated before servicing. Align the breaker with the panel’s bolt pattern, secure the mounting screws to the recommended torque, and re-verify electrical connections after installation. Proper seating and secure mounting help maintain consistent contact resistance and reliable interrupting performance.

When you need a dependable, like-for-like solution for three-phase protection, the ITE BL370 delivers precise fitment, straightforward retrofit capability, and the durability required for ongoing industrial use.
