  • 25 kA interrupting capacity at 277/408 V AC handles high fault levels
  • EverLink lugs on both ends simplify conductor termination
  • Thermal-magnetic trip gives reliable overload and short-circuit response
  • Compact 5.39 in by 3.19 in unit-mount frame fits tight panels

30 A three-pole breaker for industrial panels

The Square D BDL36030 is a molded-case circuit breaker rated at 30 amps and 525 V AC with three poles. It uses a thermal-magnetic trip unit with a fixed instantaneous setting and fits a 125 A frame size. The unit-mount design and Everlink lug terminals on both ends suit electrical distribution equipment and industrial control panels.

25 kA interrupting capacity at 277/408 V

Under sustained fault conditions the breaker delivers a maximum AIR rating of 25 kA at 277/408 V AC. The thermal-magnetic mechanism responds to prolonged overloads and short circuits without relying on adjustable instantaneous trips. Fixed-trip behaviour means the protection curve is set at the factory and does not change with vibration or temperature cycling.

Verify panel space and voltage before ordering

Confirm that the enclosure can accommodate a unit-mount breaker measuring 5.39 inches high by 3.19 inches wide. The device is not rated for DC applications, so it must only be used on AC systems. Ensure the supply voltage does not exceed 525 V AC and that the available fault current stays within the 25 kA interrupting limit at 277/408 V AC.

Questions about this item

How much heat does the 30 A BDL36030 generate when running continuously in a closed panel?

The thermal-magnetic trip unit dissipates heat proportional to the 30 A load; ensure the enclosure ventilation matches the 25 kA interrupting rating at 277/408 V AC to keep temperatures within limits.

Which mounting hardware and lugs are required to install the unit-mount BDL36030?

The breaker includes EverLink lugs on both ends for direct cable termination; you only need a compatible 125 A frame panel rail and the specified ABC phase bus bars for three-pole connection.

Will the 525 V AC, three-pole BDL36030 coordinate with an older 125 A frame feeder breaker in the same panel?

Yes, the fixed instantaneous trip and 25 kA AIR at 277/408 V AC are designed for series coordination within the 125 A BD frame family when phase connection ABC is maintained.
