Schneider Electric HDA36080 Molded Case Circuit Breaker

Schneider Electric's HDA36080 PowerPact H molded‑case circuit breaker is a three‑pole, 80 A protective device designed for 600 V AC (250 V DC) service with a thermal‑magnetic trip for reliable overload and short‑circuit protection in three‑phase panels. It uses I‑Line mounting with line‑side connections and load‑side lugs that accept AWG 14 through AWG 3/0 copper or aluminum conductors, making it suitable for distribution feeders and motor control circuits. Key ratings include an interrupting capacity of 14 kA at 600 V AC, 18 kA at 480 V AC, 25 kA at 240 V AC, and 20 kA at 250 V DC, a magnetic hold current of 800 A and a magnetic trip current of 1,450 A, and a continuous current rating of 80% of the frame. Its physical envelope measures about 9.73 in (247.14 mm) tall, 4.48 in (113.79 mm) wide, and 4.8 in (121.92 mm) deep, with a terminal tightening torque of 44.25 in‑lb (5 N·m) for secure terminations. This unit is UL 489 listed and carries additional certifications (CSA, NEMA, NMX, VDE, BS, CCC, IEC) for global use, and represents Schneider Electric’s Square D PowerPact H family in an 80 A, 3‑pole, 600 V class designed for dependable protection in industrial power distribution.
