Part of the BL series, the Siemens B14000S01 is a 40A single-pole breaker built for commercial power distribution. It features a factory-installed 120VAC shunt trip mechanism for remote circuit tripping. This bolt-on unit installs into Siemens P1 through P5 panelboards and serves as a functional substitute for BAB1040 and TEB112040 breakers. Rated for 10 kAIC at 120/240VAC, it utilizes fixed thermal-magnetic trip technology to defend against overloads and is HACR rated.
Can I install the Siemens B14000S01 in a standard residential load center?
No, this is a bolt-on BL series breaker designed specifically for commercial Siemens P1, P2, P3, P4, and P5 panelboards. It will not fit in standard residential load centers that require plug-on breakers.
What does the 00S01 suffix mean on the B14000S01 catalog number?
The 00S01 suffix indicates that the breaker is factory-equipped with a 120V AC shunt trip accessory. This allows the breaker to be tripped remotely for emergency or control applications.
How is the shunt trip accessory typically wired on this breaker?
The built-in 120V AC shunt trip is wired to a remote switch, relay, or emergency stop button. When a 120V signal is applied to the accessory leads, it mechanically trips the breaker to open the circuit.
Is the Siemens B14000S01 suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment that requires this specific protection.
Does this breaker provide GFCI or AFCI protection?
No, this is a standard thermal-magnetic breaker equipped with a shunt trip. It does not provide ground fault or arc fault protection.
