Product FAQs
7 answersWhich Siemens panelboards accept the B380HH00S01 bolt-on circuit breaker?
This Type HBL breaker is engineered to mount directly into Siemens P1, P2, P3, P4, and P5 commercial panelboards.
Does the B380HH00S01 include a factory-installed shunt trip?
Yes, the 00S01 suffix indicates this breaker is equipped with a 120VAC shunt trip mechanism. This allows the breaker to be tripped remotely via a separate electrical signal, commonly used for emergency shutdowns or fire alarm integration.
Does the B380HH00S01 provide a high interrupting rating for commercial systems?
Yes, as a Type HBL breaker, it delivers a 65kAIC rating at 240VAC, offering significantly higher fault current protection than standard BL series breakers.
What are the acceptable wire gauges for the B380HH00S01 load lugs?
The factory-installed lugs accommodate 4 to 1/0 AWG copper conductors or 2 to 1/0 AWG aluminum conductors. Ensure proper torque specifications are applied during installation to prevent loose connections.
Is the B380HH00S01 the same as a Type HBL breaker?
Yes, the B380HH00S01 catalog number corresponds to a Type HBL molded case circuit breaker within the broader Siemens BL family.
How does the thermal magnetic trip unit operate on this 80A Siemens breaker?
The fixed thermal magnetic mechanism provides dual protection: a delayed thermal response to prevent nuisance tripping during temporary overloads, and an instantaneous magnetic response to quickly clear severe short circuits.
How does the bolt-on connection benefit the B380HH00S01 installation?
The bolt-on mounting style provides a secure, vibration-resistant connection to the panelboard bus, which is critical for maintaining reliable power in commercial and industrial environments.
