The PXR20 LSIAM trip unit provides precise fault detection and adjustable protection curves that support selective coordination, helping minimize outage impact on non-faulted sections. This translates to faster fault clearance, reduced downtime, and safer operating conditions for critical lines in manufacturing, data centers, and process industries. The Magnum design delivers reliable protection even under high fault currents, enabling planners to size equipment with confidence and extend panel life through controlled trip curves. With a four-pole configuration, fixed vertical mounting, and a standard frame, integration into existing panels is straightforward, reducing installation time and field engineering costs while maintaining consistent protection across systems. Certifications and compliance enabled by UL, CE, and CSA support simplify procurement and regulatory approvals for multinational projects, lowering risk and ensuring consistent performance across sites. Compatibility with Power Xpert Protection Manager allows remote monitoring, event logging, and streamlined maintenance planning, delivering measurable uptime improvements and better asset stewardship. Zone selective interlocking and selective coordination capabilities, supported by Eaton resources, empower engineers to implement safe, scalable protection schemes that minimize cascaded outages in complex electrical networks.

FAQs

The MPSC304VEAXX2H uses a fixed vertical mounting arrangement within a standard frame and four-pole configuration, which simplifies retrofits into common low-voltage power panels and MCC enclosures. Ensure adequate clearance for connections and verify torque specs per Eaton installation guides to maintain proper fault response and arc-quench performance.
This breaker delivers a 3000 A rated current with a 100 kA interrupting capacity, four-pole construction, and the Magnum PXR20 LSIAM electronic trip unit. These specs support reliable protection against short circuits and overloads while enabling selective coordination in complex switchgear and distribution arrangements.
Yes. The PXR20 LSIAM trip unit, combined with the Magnum framework, supports selective coordination. Eaton provides application papers on zone selective interlocking to help design and validate time-current coordination. This reduces downstream outages and improves overall system reliability by limiting fault impact to the nearest upstream device.
The MPSC304VEAXX2H carries UL Listed, CE Marked, and CSA Certified designations, among others listed by Eaton. These certifications facilitate compliance with global electrical codes and enable smoother procurement for multinational projects in manufacturing, data centers, and process industries.
By improving protection accuracy, enabling remote monitoring via Power Xpert Protection Manager, and reducing nuisance trips, maintenance intervals can be extended and unplanned downtime reduced. The device leverages standard replacement parts and documented renewals, contributing to lower total cost of ownership while simplifying diagnostics and service planning.
