The Schneider Electric Masterpact NW32H2 Air Circuit Breaker (ACB) is a high‑capacity industrial circuit breaker designed for low‑voltage power distribution protection in commercial, industrial, and utility electrical systems. It is rated at 3200 A and has 4 poles (4P) for three‑phase applications with neutral. The H2 interrupting capacity code provides a high short‑circuit breaking performance (typically 100 kA or higher depending on voltage level). The breaker can be supplied as a fixed or draw‑out unit and can work with modular protection units (such as Micrologic trip units) for overload, short‑circuit, and earth‑fault protection. It conforms to international standards for low‑voltage switchgear and is suitable for main or feeder distribution panels.
