Schneider Electric SE HDA261251 Circuit Breaker

The Schneider Electric PowerPact HDA261251 is a two‑pole molded‑case circuit breaker (MCCB) from the PowerPact H family, rated 125 A for 600 V AC and 250 V DC. It is designed for I‑Line plug‑in mounting with AB phase connections (A–B), line‑side I‑Line terminals, and load‑side lugs for 14‑3/0 AWG aluminum or copper conductors, enabling straightforward panel installation and replacement. This thermal‑magnetic device provides overcurrent protection with an 80% continuous‑duty rating and an interrupting capacity of 14 kA at 600 VAC, making it suitable for protecting feeders and equipment in commercial and light industrial distributions. In a 2P configuration, it protects two conductors while maintaining reliable protection for 600 V class circuits. The HDA261251 is part of Schneider Electric’s Square D line and belongs to the PowerPact H‑frame family, which combines compact form factor with robust interrupt capabilities for distribution panels and switchgear.
