Product FAQs
6 answersWhich panelboards accept the Siemens B335H circuit breaker?
The B335H mounts via a bolt-on connection and is compatible with Siemens P1, P2, P3, P4, and P5 commercial panelboards.
What wire gauges are accepted by the B335H terminals?
The included load-side lugs accommodate 8 to 6 AWG copper conductors or 8 to 4 AWG aluminum conductors.
What is the difference between the Siemens B335 and the B335H?
Both are 35A, 3-pole breakers, but they have different short-circuit interrupting capacities. The standard B335 is rated for 10kAIC at 240VAC, while the B335H is the high-interrupting variant rated for 22kAIC at 240VAC.
Is the Siemens B335H suitable for HVAC equipment?
Yes, the B335H is fully HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration systems.
What does the LI trip function on the B335H indicate?
The LI designation means the breaker provides Long-Time overload protection and Instantaneous short-circuit protection through its thermal-magnetic trip mechanism.
Is the B335H approved for reverse feed applications?
Yes, because it utilizes a fixed, non-interchangeable thermal-magnetic trip unit, the B335H is UL listed for reverse feeding.
