Schneider Electric HDA36150U44X is a molded case circuit breaker designed for comprehensive protection of three-phase industrial power distribution systems. It provides solid-state LSIG (Long-Time, Short-Time, Instantaneous, and Ground Fault) protection with a 150A current rating and a 600V voltage rating. The breaker features a compact H-frame design measuring 163 mm H x 104 mm W x 86 mm D (6.4 in x 4.09 in x 3.4 in) and utilizes an I-Line style plug-in connection with lug terminals compatible with wire sizes from 14 AWG to 3/0 AWG for copper or aluminum conductors. It complies with UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards and is rated for operation in ambient temperatures from -2 to 70 °C (28 to 158 °F). This breaker is typically applied in panelboards and switchboards requiring an 18kA interrupting capacity at 480V AC for reliable branch circuit protection.
