FAQs

When installing the MPSC324HEAXX2S, ensure a fixed horizontal mounting arrangement and confirm adequate clearance for the four-pole assembly. Plan for the 160 lb weight and the 21.2 in width to fit enclosure openings, with proper panel space for safe wiring and future maintenance. Verify compatibility with existing bus structures and mounting rails before retrofits.
Key ratings include a 3200 A continuous current rating and 100 kA short-circuit withstand. It features a four-pole frame and the PXR25 LSIGAM trip unit for precise protection. Compatible with Power Xpert Protection Manager and suitable for high-current industrial applications, panel boards, and motor control centers.
Yes. The PXR25 LSIGAM trip unit enables selective coordination by accurately coordinating upstream and downstream protective devices. This minimizes unnecessary trips, improves system reliability, and reduces arc energy exposure, which is especially valuable in facilities with complex motor loads and stringent uptime requirements.
The device is UL Listed and ANSI certified, with CE marking and NEMA compliance. It also carries third-party verifications from Lloyd's Register, KEMA, CSA, DNV GL, and ABS, offering broad regulatory acceptance and cross-border reliability for multinational projects.
Integration with Power Xpert Protection Manager provides centralized monitoring, fault diagnostics, and coordinated protection settings, enabling predictive maintenance and faster incident response. This reduces downtime, extends equipment life, and lowers total cost of ownership through improved protection visibility and streamlined service planning.
