BQCH3B090 - 90Amp Circuit Breaker Description
BQCH3B090 - 90 Amp Circuit Breaker
The BQCH3B090 is a 90-amp, 3-pole molded case circuit breaker designed for reliable circuit protection in commercial and industrial electrical distribution systems operating up to 480VAC. Built on the BQCH frame, this bolt-on breaker is rated for 14kA interrupting capacity at 480VAC, providing dependable overcurrent and short-circuit protection for panelboards and distribution equipment. With a 40°C calibration and HACR rating, the BQCH3B090 is well-suited for HVAC applications and other demanding environments where consistent thermal-magnetic protection is required. Designed for proper form, fit, and function compatibility within BQCH series installations, this breaker helps maintain the integrity of existing electrical systems while meeting applicable industry standards. Engineered as a molded case circuit breaker (MCCB), the BQCH3B090 provides steady performance in three-phase applications where 90 amp protection is specified. Its bolt-on mounting configuration ensures secure installation within compatible panelboards, helping maintain stable electrical connections in equipment designed for BQCH frame breakers. Built to last, this unit supports ongoing maintenance and replacement needs in legacy systems without altering the original design specifications.
