The Schneider Electric Square D HDA261252 is a 125 A, 2-pole molded‑case circuit breaker in the PowerPact H family designed for I-Line installations and protection of feeders in electrical distribution panels. It is rated for 600 V AC and 250 V DC with interrupting capacities of 18 kA at 480 VAC, 25 kA at 240 VAC, 14 kA at 600 VAC, and 20 kA at 250 VDC, reflecting its suitability for a range of industrial and commercial circuits. The breaker is 80% rated and uses a thermal-magnetic trip mechanism that provides overload protection in addition to short-circuit protection. Compatible with 50/60 Hz systems, this unit is commonly used to safeguard feeders and distribution circuits within panelboards and switchgear where robust MCCB protection is required. Its 2-pole design and Square D/I-Line compatibility align with PowerPact H offerings for reliable, code‑compliant protection in demanding environments.
