FAQs
Install following the manufacturer’s installation guide: verify correct vertical mounting orientation, align the bus and disconnect hardware, connect grounding and control wiring per NEC and local codes, set the PXR20 LSIGAM trip unit to required protection levels, and perform a factory-referenced verification test. Ensure clearances, proper torque on lugs, and compliance with panel rating for reliable operation.
The PXR20 LSIGAM trip unit enables advanced protection settings, improved selective coordination, and precise fault isolation. This reduces nuisance tripping, enhances motor protection, and supports coordination studies in large distribution schemes. It’s particularly valuable in process industries and heavy automation where reliable uptime is critical.
Yes. The MPSC254WEAXX2F is designed for high-duty distribution with configurable protection features compatible with Power Xpert tools. Its 100 kA interrupting rating and four-pole, drawout configuration support selective coordination studies across industrial panels, helping to minimize disturbances and ensure proper upstream protection in both IEC and UL-listed installations.
The unit carries UL Listed, CE Marked, and CSA Certified along with additional international attestations (KEMA, Lloyd's Register, DNV GL, ABS, among others). This broad certification portfolio supports compliance across global sites, simplifies cross-border procurement, and helps meet regulatory requirements for industrial equipment in diverse markets.
Maintenance is streamlined by the drawout design and standard frame compatibility, which reduces service time and exposure during testing. The integration with Power Xpert Protection Manager enables continuous health monitoring and proactive maintenance planning, delivering improved asset uptime and potential long-term cost savings through reduced downtime and optimized protection settings.
