Product FAQs
7 answersWhich panelboards are compatible with the Siemens B23000S01?
This bolt-on miniature circuit breaker is designed specifically for use in Siemens P1, P2, and P3 panelboards.
What does the S01 suffix indicate in the B23000S01 catalog number?
The S01 suffix indicates that the breaker includes a factory-installed 120VAC shunt trip. This feature is commonly used for emergency shutdowns or integration with automated control systems.
How is the 120VAC shunt trip wired and operated?
The shunt trip requires an external 120VAC control signal. When voltage is applied to the shunt trip coil via the control wires, it mechanically trips the breaker to open the circuit, allowing for remote disconnection.
What are the acceptable wire sizes for the terminal lugs on this breaker?
The load lugs are rated to accept 10 to 8 AWG copper conductors or 10 to 6 AWG aluminum conductors.
Can the B23000S01 be used to replace older ITE bolt-on breakers?
Yes. Because Siemens acquired ITE, this authentic Siemens B-frame breaker serves as a direct replacement for legacy ITE bolt-on breakers with matching specifications.
What does the LI trip function code mean for this breaker?
The LI code indicates a thermal magnetic trip unit equipped with Long-Time (L) and Instantaneous (I) functions. This provides standard protection against both sustained overloads and sudden short circuits.
What type of connection does this breaker use?
It features a bolt-on connection, which provides a secure mechanical and electrical attachment directly to the panelboard bus.
