BQD115 - 15A Circuit Breaker

BQD115 - 15A Circuit Breaker

Searching for a BQD115 usually means one thing—you need the same breaker that's already specified for the job. This 15 amp, single-pole Siemens circuit breaker is part of the BQD series and is rated for 277VAC with a 14kA interrupting capacity. For electricians, maintenance teams, and facility managers, matching those details is often what matters most when servicing existing equipment.

The BQD115 uses a thermal-magnetic trip unit and is designed for compatible Siemens panelboard applications. Its single-pole design is frequently found protecting individual branch circuits, particularly in commercial buildings where 277-volt lighting systems are common. Because of its compact molded case construction, it fits where a BQD-series breaker is already installed and specified.

You'll find breakers like the BQD115 in schools, office buildings, healthcare facilities, retail spaces, warehouses, and manufacturing plants.

Where It Works Best

• The Siemens BQD115 is regularly used in commercial and industrial electrical distribution systems that require a 15 amp, 1-pole, 277VAC circuit breaker.
• For replacement work, the most important factors are usually the breaker series, amperage, voltage rating, pole configuration, and interrupting capacity. The BQD115 matches equipment designed around those specifications.
