Product FAQs
7 answersWhat does the 00S01 suffix indicate on the Siemens B320H00S01?
The 00S01 suffix designates a factory-installed 120V AC shunt trip. This internal accessory allows the breaker to be tripped remotely via an external control signal, which is commonly used for emergency shutdowns or automated control systems.
What is the difference between the Siemens B320H and the B320H00S01?
Both are 20A, 3-pole, B-frame breakers with a 22kAIC rating at 240VAC. The B320H00S01 includes a factory-installed 120V AC shunt trip for remote disconnect applications, whereas the standard B320H does not include this internal accessory.
Which panelboards are compatible with the B320H00S01 circuit breaker?
This bolt-on circuit breaker is designed specifically for installation in Siemens P1, P2, and P3 panelboards.
How is the B320H00S01 secured inside the panelboard?
It features a bolt-on connection, meaning it fastens directly to the panelboard bus bars with screws. This provides a secure, vibration-resistant connection typical in commercial and industrial environments.
Does the B320H00S01 require a separate control circuit for the shunt trip?
Yes, the factory-installed 120V AC shunt trip requires a dedicated control power source and an external switching device, such as a push button or relay, to send the voltage signal that trips the breaker.
What wire sizes and materials are approved for the lugs on this breaker?
The load side lugs accept 14-10 AWG copper (Cu) wire or 12-10 AWG aluminum (Al) wire.
How does the thermal-magnetic trip unit function on this breaker?
The fixed thermal-magnetic trip unit provides two types of protection. The thermal element responds to prolonged overcurrents for long-time protection, while the magnetic element trips the breaker immediately during a short circuit for instantaneous protection.
