CH290 - 90Amp Circuit Breaker

CH290 - 90Amp Circuit Breaker

The CH290 is a 90 Amp, 2-pole Type CH circuit breaker designed for use in compatible 120/240VAC electrical distribution systems. Featuring a convenient plug-on mounting design, this breaker is commonly installed in residential, commercial, and light industrial applications where a higher-amperage branch circuit requires dependable overcurrent protection.

When you're replacing an existing breaker, compatibility is often the first concern. The CH290 is built for applications that call for a Type CH breaker and provides the amperage, voltage, and interrupting ratings needed for many demanding electrical loads. With its 90-amp rating, this breaker is frequently used for larger HVAC equipment, electric heating systems, pumps, compressors, water heating equipment, and other high-power 240-volt applications.

Rated at 10kA interrupting capacity at 120/240VAC, the CH290 is designed to help protect conductors and connected equipment from damage caused by overloads and short-circuit conditions. Its compact footprint allows it to fit compatible CH panel installations without occupying additional panel space. Whether your project involves routine maintenance, service upgrades, equipment replacement, or panel repairs, the CH290 provides the specifications electricians and maintenance professionals look for when selecting a compatible replacement breaker.
