BQD290 - 90Amp Circuit Breaker Description
BQD290 - 90Amp Circuit Breaker
The Siemens BQD290 is a 90-amp, 2-pole molded case circuit breaker intended for use in 480/277VAC electrical distribution systems. It provides overcurrent protection for branch circuits, helping prevent damage caused by overloads and short circuits. The breaker utilizes a thermal magnetic trip mechanism that responds to both prolonged overcurrent conditions and instantaneous fault events.
Designed for your panelboard installation, the BQD290 is part of the Siemens BQD series and features a low-tab connection style along with a molded case construction. Its 14 kAIC interrupting rating makes it suitable for a wide range of commercial and industrial applications. This breaker is frequently used in lighting distribution panels, HVAC systems, control panels, and general power distribution equipment where a 90-amp, two-pole breaker is specified.
