Square D HOM290 is a 2-pole, 90A standard molded case circuit breaker from the HOMELINE family, designed for thermal magnetic overcurrent protection in residential and light commercial Homeline load centers. This plug-in breaker operates at 120/240V with a 10kA interrupting capacity at 240V, providing LI (long-time and instantaneous) trip functions for branch circuit protection. Measuring 3.13 in (79.50 mm) x 2 in (50.8 mm) x 2.98 in (75.69 mm) and weighing 0.855 lb, it features a 100A/HOM frame size with lug terminals accepting 1x AWG 4 to AWG 2/0 aluminum/copper wire (minimum 8 AWG, maximum 2 AWG). The device is CSA certified, HACR rated, and UL listed, operating within a temperature range of -13 to 158 °F (-25 to 70 °C) for single-phase applications. Typical industrial applications include branch circuit protection in Homeline load centers for lighting, appliance, and general-purpose circuits requiring 90A capacity.
