QCB90 - 90 Amp Circuit Breaker

QCB90 - 90 Amp Circuit Breaker

The QCB90 is a 90 amp, 2-pole circuit breaker used for higher-load electrical circuits in residential, commercial, and light-industrial settings. It’s designed to shut power off when a circuit is overloaded or shorted, helping protect wiring and connected equipment. This breaker fits standard panels and has a compact profile, which makes it easier to install in tight spaces or replace an existing unit. It’s commonly used when steady, two-pole protection is needed for equipment that draws more current than typical branch circuits. Nothing complicated here—just a breaker built to do its job reliably.
