The Square D JJM36150 is a 3-pole molded case circuit breaker from the Powerpact family, designed for thermal magnetic overcurrent protection in industrial power distribution systems. It is rated for 600V AC, 150A continuous current, and provides a 65kA interrupting capacity at 480V AC with LI (Long-Time and Instantaneous) trip functions. This J Frame breaker measures 7.5 in (191 mm) x 4.09 in (104 mm) x 3.4 in (86 mm), weighs 5 lb, and features a bolt-on connection with AWG 4 to AWG 4/0 aluminum/copper terminals. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards, operating within a temperature range of 28-158 °F (-2-70 °C). Typical applications include motor control centers, panelboards, and switchboards in commercial and industrial facilities requiring reliable branch circuit protection.
