A high-capacity solution for commercial applications, the Siemens B230H is a 30-amp, 2-pole molded case circuit breaker. It utilizes fixed thermal and magnetic trip elements for precise protection. This BLH type breaker bolts into Siemens P1 panelboards. It is also an approved substitute for BAB2030H and QOB230VH models, making it a versatile choice. With a 22kAIC rating at 120/240VAC, it handles demanding fault conditions. The unit is HACR rated and comes with load side lugs.

Product FAQs
6 answers
What panelboards accept the Siemens B230H breaker?
This breaker is specifically designed to bolt into Siemens P1 panelboards for commercial power distribution.
What is the difference between the Siemens B230 and B230H breakers?
While both are 30-amp, 2-pole breakers for P1 panels, they differ in their short circuit interrupting ratings. The standard B230 is rated for 10kAIC, whereas the B230H provides a higher 22kAIC rating for commercial applications with higher available fault currents.
Is this 30-amp breaker approved for HVAC equipment?
Yes, the B230H is HACR rated. This means it has been tested and certified for safe use with heating, air conditioning, and refrigeration equipment, capable of handling heavy compressor motor inrush currents.
Why use a bolt-on breaker like the B230H instead of a plug-in style?
Bolt-on breakers attach directly to the panelboard bus with screws or bolts. This creates a highly secure, vibration-resistant mechanical and electrical connection that prevents arcing and loosening in demanding commercial and industrial environments.
Can the Siemens B230H replace BAB2030H or QOB230VH breakers?
Yes, this model is recognized as an approved substitute for both BAB2030H and QOB230VH circuit breakers.
How does the thermal magnetic trip mechanism clear electrical faults?
The thermal bimetal element provides a time-delayed trip to safely clear sustained overloads without nuisance tripping. The magnetic coil reacts instantly to break the circuit in the event of a severe, high-current short circuit.
