418 products
These miniature circuit breakers are compatible with Siemens panelboards and load centers and interrupt the flow of current when low-level faults are detected. They prevent damage caused by overcurrents and short circuits in residential, light commercial, and industrial applications where sensitive circuit protection is needed.
B Series, Bolt-On Siemens Miniature Circuit Breakers
These B series miniature circuit breakers are bolted into place in panelboards, so they're more stable than plug-in breakers. They interrupt currents when low-level faults are detected in the circuit. They have a lug orientation to allow for straight-in wiring through bus bars, which eliminates the need to pigtail wires and helps organize the panelboard.

Q Series, Plug-In Siemens Miniature Circuit Breakers
These Q series miniature circuit breakers plug into place in panelboards and EQ load centers and don't require bolting, so they're easier to install than bolt-on breakers. They interrupt currents when low-level faults are detected in the circuit. They connect to the power supply through bus bars, which eliminates the need to pigtail wires and helps organize the panelboard or load center.
