Product FAQs
5 answersWhat does the 00S01 suffix mean on the Siemens B220HH00S01?
The 00S01 suffix indicates that this breaker includes a factory-installed 120V AC shunt trip accessory. This allows the breaker to be tripped remotely by applying a 120V control signal, which is commonly used for emergency stops or automated safety shutdowns.
Can I install the B220HH00S01 in a standard residential load center?
No. This is a bolt-on breaker designed specifically for commercial and industrial Siemens P1, P2, and P3 panelboards. It will not fit in standard plug-on residential load centers.
Why is this breaker designated as HBL instead of a standard BL?
The HBL designation, noted by the HH in the B220HH00S01 catalog number, indicates an extra-high interrupting capacity. While standard BL breakers are typically rated at 10kAIC, this HBL version can safely interrupt up to 65kAIC at 120/240VAC, making it suitable for facilities with higher available fault currents.
How does the thermal-magnetic trip unit in the B220HH00S01 operate?
The thermal-magnetic mechanism provides two levels of protection. The thermal component offers a long-time delay to prevent nuisance tripping during temporary, minor overloads, while the magnetic component provides an instantaneous trip to quickly clear severe short circuits.
What are the acceptable wire materials and sizes for the load lugs on this breaker?
The load-side lugs are rated for both copper and aluminum conductors. They accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire.
