The Schneider Electric HOMELINE CHOM290 is a 90A, 2-pole molded case circuit breaker designed for overcurrent protection in residential and light commercial load centers. It operates at 240V with a 10kA@240V interrupting capacity and provides LI (Long-Time and Instantaneous) protection through a thermal magnetic trip mechanism. This plug-in breaker measures 4.44 inches in width and 3.09 inches in depth, weighs 0.85 lb, and accepts AWG 4 to AWG 2/0 aluminum or copper wire. It is CSA certified and rated for a maximum ambient temperature of 104 °F (40 °C), making it suitable for single-phase panelboard applications.
