Schneider Electric H322NRB Molded Case Circuit Breaker

Schneider Electric H322NRB Molded Case Circuit Breaker (Square D H322NRB) is a three-pole molded‑case protection device in the PowerPact H‑Frame family, designed to provide reliable overcurrent protection for distribution circuits in commercial and light‑industrial panels. It combines a thermal‑magnetic trip mechanism with a rugged housing suitable for panelboard and switchgear installations, and it is offered under the Square D brand, a long‑standing Schneider Electric line. The H322NRB is intended for use where fast isolation and dependable fault protection are required, such as industrial control panels, motor control centers, and electrical distribution enclosures. As part of the PowerPact line, it supports standard mounting configurations and is compatible with common H‑Frame MCCB accessories and enclosures, allowing integration with backplanes, bus bars, and auxiliary contacts where applicable. Because exact ratings vary by regional variant, buyers should consult the official Schneider Electric datasheet for the H322NRB to confirm current, voltage, interrupting capacity, and installation details before selection or replacement.
