BQ3B070H - 70Amp Circuit Breaker Description
BQ3B070H - 70Amp Circuit Breaker
The Siemens BQ3B070H is a 70-amp, 3-pole molded case circuit breaker for your 240V systems. Its common-trip design opens all three poles at the same time during an overload or short circuit, helping protect your wiring and connected equipment. This breaker includes a 24V auxiliary switch and factory-installed load-side lugs, with a bolt-on connection for straightforward installation in Siemens-compatible panelboards and distribution equipment.
Rated for 22 kA interrupting capacity and UL 489 listed, the BQ3B070H is used in commercial offices, schools, retail spaces, warehouses, and light industrial facilities. Its compact molded case fits neatly in panels and load centers, providing 3-pole protection for branch circuits, feeder circuits, and HVAC systems. It’s suitable for replacements or maintenance in existing Siemens systems, especially where monitoring or control via the auxiliary switch is needed.
