FAQs

The MPSC124VEAXX2H uses fixed vertical mounting and a four-pole configuration, designed for straightforward retrofit into standard low-voltage switchgear enclosures. Its dimensions (approximately 14.6 in depth, 16.8 in height, 21.2 in width) and 160 lb weight should be accounted for in door clearance and mounting rails. This simplifies alignment with existing bus and bussing, reducing commissioning time and risk during upgrades.
The PXR20 LSIAM electronic trip unit delivers advanced protection logic with adjustable instantaneous settings and processor-based safety checks, enabling tighter selective coordination with neighboring devices. This reduces nuisance trips, improves fault isolation speed, and helps meet insulation coordination requirements in large motor or feeder networks, which is critical for uptime in continuous-process facilities.
Yes. With a 1200 A frame rating and 100 kA interrupting capacity across a four-pole configuration, this breaker handles demanding motor loads and critical power feeds while maintaining reliable protection. Its compatibility with Power Xpert tools and zone-selective interlock concepts further enhances protection coordination and uptime in data centers, manufacturing lines, and automated facilities.
The MPSC124VEAXX2H carries UL Listed, CE Marked, and NEMA compliant certifications, among others. These approvals support global acceptance, regulatory alignment, and easier procurement for multinational projects. Verifying these certifications helps ensure the device meets regional electrical codes, installation practices, and safety requirements.
Eaton provides extensive documentation including specification sheets, application notes, and user guides, plus renewal parts and accessory literature. Resources like the Magnum PXR product aid and protection-manager guides help optimize maintenance schedules, while practical data on fault curves and selective coordination supports faster ROI through reduced downtime and streamlined servicing.
