Product FAQs
7 answersWhat panelboards are compatible with the Siemens B330H?
This bolt-on breaker is designed for direct mounting into Siemens P1, P2, P3, P4, and P5 panelboards. It requires three pole spaces and fits standard B-frame or BLH footprints.
Is the Siemens B330H circuit breaker rated for HVAC equipment?
Yes, this unit is HACR rated. It is fully approved to protect branch circuits serving heating, air conditioning, and refrigeration equipment.
What are the wire size requirements for the B330H?
The factory load lugs accept 14 to 6 AWG copper conductors or 12 to 6 AWG aluminum conductors. Always refer to the breaker label for proper torque specifications prior to terminating.
What is the difference between Siemens BL and BLH circuit breakers?
Standard BL breakers carry a 10kAIC rating at 240VAC. BLH models like this one are high-interrupting versions that offer a 22kAIC rating while maintaining the exact same physical dimensions and bolt-on requirements.
How does the trip unit operate on this 30A breaker?
It features a fixed, non-interchangeable thermal magnetic trip mechanism. The thermal element provides long-time protection against continuous overloads, while the magnetic element provides instantaneous protection to clear severe short circuits.
What industry safety standards apply to the B330H?
This breaker is UL 489 listed and CSA certified, making it compliant for commercial and industrial low voltage branch circuit protection.
Can the Siemens B330H be reverse fed?
Yes. Because the thermal magnetic trip unit is fixed and not removable, standard Siemens BLH series breakers like this model are suitable for reverse feed applications per UL 489 guidelines.
