Power Xpert Release (PXR20 LSIG) trip unit delivers precise protection and selectivity, reducing nuisance trips while enabling accurate coordination across feeders. This improves uptime and simplifies maintenance planning in mid-to-large switchgear, MCCs, and distribution panels. Drawout vertical mounting with motorized racking enables safer, faster maintenance and expedited breaker replacement, minimizing plant downtime and labor costs. The unit supports high fault currents with an 85 kA short-circuit withstand and a 6000 A interrupting capability, ensuring robust protection for demanding industrial loads and helping meet strict electrical standards. Fan cooling maintains trip-unit performance in hot environments, extending component life and reducing misoperation risk in high-density panels. Global certifications (UL Listed, CE Marked, CSA Certified) facilitate regional deployments, while its dimensions and weight aid in accurate panel planning and retrofit projects.

FAQs

The MPS8603MEAXX2C uses a drawout vertical mounting with motorized racking, designed for safe, fast breaker replacement. Installation requires ensuring the panel supports vertical drawout devices, connecting the racking mechanism, and verifying alignment with bus bars and accessories. Follow the included Magnum PXR installation manual for proper torque values and sequencing to maintain selectivity and safety.
It utilizes the Power Xpert Release trip unit (PXR20 LSIG), delivering accurate long-time, short-time, and instantaneous protection with selectivity across feeders. This enables coordinated fault isolation, reduces arc energy exposure, and supports easier integration with Power Xpert Protection Manager for centralized monitoring.
Yes. As a three-pole, drawout breaker with motorized racking, high interrupting rating, and selective-coordination-capable trip unit, it is well-suited for MCCs and feeder circuits in manufacturing plants and data centers. Its footprint and modular design simplify installation, while the 85 kA withstand rating helps manage high fault currents typical in dense switchgear environments.
This unit is UL Listed, CE Marked, and CSA Certified, with additional certifications from Lloyd’s Register and other bodies. These recognitions support regional compliance, facilitate global procurement, and help meet industry standards for electrical protection in multi-site operations.
The motorized racking and PXR20 LSIG trip unit enable faster maintenance, safer service procedures, and reduced downtime. The unit’s durability, high fault-current rating, and global certifications contribute to lower lifecycle costs through extended service intervals, improved uptime, and easier regulatory compliance across regions.
