Product FAQs
6 answersCan I install the B280H00S01 in a standard residential load center?
No, this is a bolt-on circuit breaker designed specifically for commercial and industrial Siemens P1, P2, and P3 panelboards. It is not compatible with standard plug-on residential load centers.
What does the 00S01 suffix in the B280H00S01 catalog number indicate?
The 00S01 suffix designates that this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely by applying a 120V signal to the shunt trip coil, which is commonly used for emergency stops or automated safety shutdowns.
Is the B280H00S01 interchangeable with standard BL series breakers?
This breaker shares the same physical footprint as standard B-frame or BL breakers, but it is specifically a BLH type. The BLH designation indicates a higher interrupting rating of 22kAIC at 240V, compared to the standard 10kAIC of base BL breakers.
What type of conductors are permitted for use with the B280H00S01 lugs?
The factory-installed lugs are dual-rated for both copper and aluminum conductors. They accept 4 AWG to 1/0 AWG copper wire, or 2 AWG to 1/0 AWG aluminum wire. Always verify the required torque specifications printed on the breaker label before terminating.
How does the B280H00S01 connect to the panelboard bus?
This is a bolt-on breaker, meaning it requires mechanical fasteners to secure the line-side connections directly to the panelboard busbars. This provides a secure, high-vibration resistant connection typical in commercial P1, P2, and P3 panels.
Does the B280H00S01 provide adjustable trip settings?
No, this breaker features a fixed thermal-magnetic trip unit. It provides non-adjustable long-time and instantaneous (LI) overcurrent protection.
