Product FAQs
6 answersWhat does the 00S01 suffix mean on the Siemens B310000S01?
The 00S01 suffix indicates that this breaker includes a factory-installed 120VAC shunt trip accessory. This allows the breaker to be tripped remotely by applying a 120V control signal.
Which panelboards are compatible with the B310000S01 circuit breaker?
This BL series bolt-on breaker is designed exclusively for Siemens P1, P2, P3, P4, and P5 commercial panelboards. It will not fit in standard plug-on residential load centers.
What does the LI trip function indicate for this breaker?
The LI designation means this thermal-magnetic breaker provides Long-Time (thermal) protection against sustained overloads and Instantaneous (magnetic) protection against short circuits.
Does the B310000S01 require a separate control circuit for the shunt trip?
Yes. To utilize the factory-installed 120VAC shunt trip, you must wire a separate 120V control signal to the accessory leads to enable remote tripping.
Is the Siemens B310000S01 HACR rated?
Yes, this breaker is HACR certified, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
Is it safe to install this breaker while the panelboard is energized?
No. Always de-energize the panelboard before installing or servicing bolt-on circuit breakers to prevent arc flash and electrical shock hazards. Lock out and tag out the power source prior to installation.
