Schneider Electric HJA36100U33X Circuit Breaker

Schneider Electric’s Square D PowerPact H line 100 A three‑pole molded‑case circuit breaker, model HJA36100U33X, is designed for 600 V AC distribution with I‑Line plug‑in terminals for rapid substitution in compatible panels. Rated at 100 A and offering a 25 kA short‑circuit rating at 600 V, the device protects three‑phase circuits against overloads and faults while fitting within the PowerPact H frame. It employs the Micrologic 3.2S electronic trip unit to deliver long‑time, short‑time, and instantaneous protection, with an 80% continuous‑load rating appropriate for load profiles that run below the full rated current. The HJA36100U33X is UL listed and commonly used in industrial and commercial electrical installations that require reliable, coordinate protection for 600 V systems, including distribution panels and switchgear where I‑Line bus configurations are standard. Typical applications include motor control circuits, processing lines, and general three‑phase power distribution where space and quick breaker replacement are priorities.
