Four-pole Magnum frame with a PXR20 LSIAM trip unit delivers precise protection and improved trip coordination. The resulting selectivity minimizes unnecessary outages and reduces arc-flash exposure for operators, while staying compatible with standard panelboards and switchgear in manufacturing facilities. High-current capability: with a 3200 A rating and 100 kA breaking capacity, the breaker tolerates large fault currents without compromising safety. This translates to improved reliability for main feeders and critical motor circuits in heavy-industry plants, reducing unplanned downtime. Fixed horizontal mounting and four-pole configuration simplify installation in standard enclosures, lowering field setup time and wiring errors during retrofit or new-build projects. Certifications such as UL Listed, ANSI, and CE Marked support global deployment and regulatory compliance across diverse facilities. Power Xpert Protection Manager compatibility, alongside available application papers and quick-start guides, accelerates commissioning and reduces maintenance costs over the lifecycle of the installation.
