Product FAQs
5 answersWhat does the S01 suffix indicate on the B37000S01 part number?
The S01 suffix designates that this breaker includes a factory-installed 120VAC shunt trip. This accessory allows the circuit to be opened remotely by a control switch or automated system.
What specific frame type is the Siemens B37000S01?
While it belongs to the broader Siemens B family, this specific model is a BL frame molded case circuit breaker designed for bolt-on panelboard mounting.
What safety and testing standards does this BL frame breaker meet?
The B37000S01 is UL 489 listed and CSA C22.2 certified for use in commercial and industrial electrical distribution systems. It is also HACR rated for heating, air conditioning, and refrigeration applications.
How is the B37000S01 secured inside the panelboard?
This is a bolt-on breaker, meaning it fastens directly to the busbar of compatible Siemens P1, P2, or P3 panelboards. This provides a highly secure connection that resists vibration in commercial environments.
What type of conductors can be used with the load lugs on this 70A breaker?
The integrated lugs are dual-rated for copper and aluminum conductors. They accept 4 AWG to 1/0 AWG copper wire, or 2 AWG to 1/0 AWG aluminum wire.
