Siemens BR2 Bq 2-pole Back Mount Circuit Breaker

Product Description

The SIEMENS BR2 is a BQ-series 2-pole back mount circuit breaker designed for branch circuit overcurrent protection in residential and light commercial electrical panels. It provides automatic disconnection of a circuit when current exceeds rated capacity, protecting wiring and connected equipment from damage. The back mount configuration positions the breaker for installation in compatible load centers and enclosures. Licensed electricians install this breaker as part of panel construction, service upgrades, or circuit additions. Its dual-pole design handles 240-volt circuits or paired 120-volt loads depending on the application.

The BR2 is suited for residential load centers and light commercial panelboards where BQ-series back mount breakers are specified. Typical applications include branch circuits for HVAC equipment, appliances, subpanels, and general-purpose 240-volt loads. The back mount style is common in enclosures and panels that require breakers seated from the rear of the bus assembly rather than the front clip-on style.

Compatibility

Designed as an OEM-style replacement or new-install 2-pole back mount circuit breaker for BQ-series compatible Siemens load centers and enclosures.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize the panel and verify the main breaker is off before handling any bus or breaker components. Back mount breakers require correct seating against the bus stabs — confirm full engagement before restoring power. Do not install in panels that are not rated for BQ-series back mount breakers.
