Description
Engineered for demanding environments, the Siemens B320HH00S01 is a high-interrupting HBL series circuit breaker. It offers robust thermal-magnetic protection for 240V three-phase systems. This 20A breaker installs into Siemens P1, P2, and P3 panelboards using a standard bolt-on connection. Distinguished by its 65 kAIC rating, it safely handles severe fault currents. It also includes a factory-installed 120VAC shunt trip for remote disconnect capabilities.Specifications

Product FAQs
6 answersWhat panelboards accept the Siemens B320HH00S01?
This B-frame breaker features a bolt-on connection designed specifically for Siemens P1, P2, and P3 panelboards. It is not compatible with standard load centers that require plug-in breakers.
What does the 00S01 suffix indicate on this catalog number?
The 00S01 suffix designates that this breaker includes a factory-installed 120VAC shunt trip accessory for remote tripping applications.
Can I replace a standard B320HH with the B320HH00S01?
Both breakers share the same 20A, 3-pole HBL frame and 65kAIC rating. However, the B320HH00S01 includes a 120VAC shunt trip. If your application does not require a remote trip function, the standard B320HH is typically used.
How does the HBL series differ from standard BL breakers?
The HBL series designates the high-interrupting tier of the Siemens BL family. The B320HH00S01 delivers a 65kAIC rating at 240VAC, whereas standard BL breakers have lower short-circuit interrupting capabilities.
Are the trip settings on the B320HH00S01 adjustable?
No, this breaker is equipped with a fixed thermal-magnetic trip unit. The long-time (thermal) and instantaneous (magnetic) protection thresholds are factory calibrated and cannot be modified in the field.
Does the B320HH00S01 accept aluminum wiring?
Yes, the factory lugs are rated for both copper and aluminum conductors. They accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire.
