Product FAQs

6 answers
Which Siemens panelboards accept the B245H00S01 circuit breaker?

This 2-pole breaker is compatible with Siemens P1, P2, P3, P4, and P5 panelboards. It utilizes a bolt-on connection to secure directly to the panel bus.

What does the 00S01 suffix mean on the Siemens B245H00S01?

The 00S01 suffix indicates that this breaker includes a factory-installed 120V shunt trip. This internal accessory allows the breaker to be opened remotely using an external voltage signal.

What wire gauge is required for the lugs on this 45A breaker?

The terminal lugs accommodate 8 to 6 AWG copper conductors or 8 to 4 AWG aluminum conductors. Ensure proper torque specifications are applied during installation.

What is the difference between Siemens BL and BLH breakers?

The BLH type is the higher-interrupting version of the standard BL frame. While standard BL breakers offer a 10kAIC rating, the BLH series provides a 22kAIC interrupting capacity at 120/240VAC.

How does the LI trip function operate on the B245H00S01?

The LI designation indicates a thermal magnetic trip unit. The fixed thermal element provides long-time (L) protection against overloads, while the fixed magnetic element delivers instantaneous (I) protection against short circuits.

Can the B245H00S01 be installed in 277/480V systems?

No, this circuit breaker is strictly rated for 120/240VAC applications. It does not have the necessary voltage rating or clearances for 277V or 480V systems.
