FAQs

For installation, plan for four-pole, drawout vertical mounting to enable easy maintenance and safe clearance around the device. The unit weighs 319 lb and spans 44.1 in in width with 16.8 in height and 16.3 in depth, so allocate adequate panel footprint and allow wiring space. Ensure compatibility with standard Eaton enclosures and the PXR protection scheme for proper coordination.
Key specs include an 85 kA short-circuit withstand rating and a 6000 A frame rating, four-pole construction, and a PXR25 LSIGAM trip unit. These factors support precise protection, high fault tolerance, and reliable operation in heavy-load panels, with adequate headroom for motor starts and process line disturbances.
This breaker excels in industrial control panels, machine rooms, and process lines that require selective coordination and robust fault protection. It supports high-demand motors and feeders, enabling reliable operation in manufacturing environments and facilitating scalable protection strategies as systems expand.
The unit carries UL Listed, CSA Certified, and CE Marked certifications, with ANSI and Lloyd's Register recognition. These markings signal compliance with global safety and performance standards, easing cross-border procurement, audits, and installation in regulated environments.
Expect shortened commissioning and maintenance cycles due to drawout mounting and clear wiring paths, plus reduced downtime from reliable high-current protection (85 kA). Access to specification sheets, manuals, and renewal parts supports long-term service life and predictable total cost of ownership across multi-site deployments.
