Description
Built for demanding environments, the Siemens B220H00S01 2-pole, 20A molded case circuit breaker operates within the BLH series. The breaker mounts into Siemens P1 through P5 panelboards. Its bolt-on configuration guarantees a reliable connection, and it serves as a functional equivalent to BAB2020H and QOB220VH models. Distinguishing itself with a 22kAIC interrupting capacity, it handles higher fault currents. A factory-installed 120VAC shunt trip allows for remote operation.Specifications

Product FAQs
5 answersWhat does the 00S01 suffix indicate on the B220H00S01 breaker?
The 00S01 suffix means this breaker is equipped with a factory-installed 120V AC shunt trip. This feature requires a separate 120V control circuit and allows the breaker to be tripped remotely for emergency stops or automated safety shutdowns.
Which panelboards accept the Siemens B220H00S01 circuit breaker?
This bolt-on breaker is compatible with Siemens P1, P2, P3, P4, and P5 panelboards. It requires a bolted connection directly to the panel bus and cannot be used in standard residential plug-on load centers.
How does the BLH type differ from standard BL breakers?
The BLH designation indicates a higher interrupting capacity. While standard Siemens BL breakers are rated for 10kAIC, this BLH model provides a 22kAIC rating at 240V for systems with higher available fault currents.
What wire sizes are supported by the load lugs on this 20A breaker?
The factory-installed lugs accept 14 to 10 AWG copper conductors or 12 to 10 AWG aluminum conductors.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal-magnetic trip unit provides Long-Time and Instantaneous (LI) protection. The thermal element responds to sustained overloads, while the magnetic element trips the breaker immediately during a short circuit.
