Product FAQs

5 answers
What does the 00S01 suffix indicate on the Siemens B340H00S01?

The 00S01 suffix designates a factory-installed 120VAC shunt trip mechanism. This allows the breaker to be tripped remotely via an external control signal.

What is the difference between Siemens BL and BLH series circuit breakers?

The BLH series features a higher interrupting rating of 22kAIC at 120/240VAC, whereas standard BL series breakers are rated for 10kAIC. The B340H00S01 is a BLH type breaker designed for systems requiring this higher fault current capacity.

How is the B340H00S01 installed into Siemens panelboards?

This breaker features a bolt-on connection that fastens directly to the bus bars of Siemens P1, P2, P3, P4, and P5 panelboards. This provides a secure mechanical and electrical connection for commercial distribution systems.

Is the Siemens B340H00S01 suitable for HVAC applications?

Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment.

How does the integrated shunt trip on the B340H00S01 operate?

The factory-installed shunt trip requires a 120VAC control signal. When energized, it mechanically trips the breaker to open the circuit, making it ideal for emergency disconnects and safety interlock systems.
