FAQs
This model is designed for drawout vertical mounting with motorized racking and a standard Magnum frame. Plan for three-pole protection, adequate clearance, and compatible switchgear rails. Ensure mounting aligns with the unit’s 16.2 in width and 16.8 in height, and observe the 14.6 in depth for proper enclosure fitment. Verify ambient temperature and enclosure rating requirements per site standards before installation.
The breaker provides a 2000 A continuous current rating with a 100 kA short-circuit current rating, three-pole configuration, and a drawout vertical design. It is equipped with a PXR20 LSIG trip unit and is part of Eaton’s Magnum family for high-reliability protection in low-voltage power distribution.
Yes. The 2000 A/100 kA rating supports high-load motors, while the PXR20 LSIG trip unit enables precise protection and coordination. For enhanced selectivity, consult application notes such as selective coordination papers, and consider zone selective interlocking to reduce energy and improve fault discrimination in complex motor feeders.
The unit is UL Listed and CE Marked, with ANSI and CSA certifications noted, along with additional third-party certifications like Lloyd's Register and KEMA. This broad certification set supports global deployment and compliance with common industry standards.
The Magnum breaker is compatible with Power Xpert Protection Manager, including quick-start guides and software assets. Integration enables centralized protection settings, faster fault analysis, and simplified maintenance planning, driving reduced downtime and clearer ROI for your protection infrastructure.
