BQ3B07000S01 - 70Amp Circuit Breaker

BQ3B07000S01 - 70Amp Circuit Breaker

The Siemens BQ3B07000S01 is a 70-amp, 3-pole circuit breaker used in 240V three-phase distribution systems. It combines standard overcurrent protection with a factory-installed 120VAC shunt trip, allowing the breaker to be opened remotely from a control circuit when needed. This type of configuration is often found in applications where emergency shutdown capability or remote operation is part of the system design.

Built on Siemens' Type BQ platform, this breaker uses a common-trip mechanism that opens all three poles together during a fault condition. The bolt-on design provides a secure connection in compatible equipment, and load-side lugs are included. A 10 kA interrupting rating makes it suitable for a variety of commercial and industrial installations, including panelboards, HVAC equipment, machinery disconnect circuits, and distribution panels.

Whether you're replacing an existing unit or maintaining a Siemens electrical system, the BQ3B07000S01 provides the ratings and functionality required for applications that call for a 70-amp, 3-pole breaker with remote tripping capability. Like many Siemens molded case breakers, it was built for long service life in everyday electrical distribution environments.
