Protects circuits at 30 A with a 22 kA interrupting rating on 120/240 V AC panels

  • 30 A protection for single-phase 120/240 V AC circuits
  • 22 kA interrupting rating clears high fault currents safely
  • Bolt-on mounting fits Siemens P1 panelboards directly
  • Lug terminals accept 14 AWG copper or 12 AWG aluminium wire
  • Compact 125 A frame saves space in the load centre

SIEMENS B230H 30 A Miniature Breaker

The SIEMENS B230H is a 30-ampere, two-pole miniature circuit breaker rated for 120/240 V AC. It uses the BL series bolt-on mounting style and fits Siemens P1 panelboards. The toggle actuator provides manual switching for single-phase branch circuits. It is intended for residential and light-commercial electrical panels.

Capacity and headroom: 22 kA interrupting

The breaker carries a 22 kA AIR rating at its full voltage rating, giving substantial short-circuit headroom for typical service-entrance and branch loads. The 125 A frame size limits continuous current to 30 A on this unit, so larger feeder circuits require a different frame. It is not rated for DC applications.

Lug terminals accept 14 AWG copper

Terminal lugs are listed for a minimum of 14 AWG copper and 12 AWG aluminium conductors. Bolt-on mounting secures the breaker directly to the panel bus without stab connectors. The breaker has no DC voltage rating, so it must not be used on direct-current circuits.

Questions about this item

Will this 30 A, 2-pole breaker fit in my existing Siemens P1 panelboard?

Yes, it is designed for Siemens P1 panelboards and uses a bolt-on mounting style with a 125 A/BLH frame size.

How can I confirm the breaker is operating correctly after installation?

Switch the toggle actuator to the on position and verify that the connected 120/240 V AC circuit carries load without tripping; the breaker is rated for 22 kA AIR at that voltage.

Does the package include the lug terminals or must I purchase them separately?

The breaker comes with a terminal connection lug; minimum wire sizes are 14 AWG copper or 12 AWG aluminium.
