FAQs

Installation requires proper panel clearance for the 31.1 in width and a safe lifting plan for the 237 lb unit. Use the motorized racking feature to rack the breaker in and out of the busbar, following the manufacturer’s alignment guides and torque specs for mounting hardware. Ensure three-pole configuration matches your panel’s phase layout and verify neutral and ground connections per local codes. Plan for panel space, access, and lockout-tagout procedures to minimize risk during commissioning.
The device is a three-pole, 4000 A frame with a 100 kA interrupting capacity, meaning it can safely interrupt high fault currents in demanding systems. It is shipped without a trip unit, allowing you to select a compatible protection module to meet your coordination needs. The 16.3 in length, 16.8 in height, and 31.1 in width define its footprint for enclosure planning.
Yes, it suits data centers and manufacturing lines requiring robust fault protection and reliable maintenance workflows. Its drawout design with motorized racking supports quick replacements and testing without extensive downtime. UL Listed and CSA Certified marks, plus CE and other certifications, help ensure regulatory compliance across regions and ease of procurement for multinational facilities.
The product holds UL Listed, CSA Certified, KEMA Certified, ANSI, Lloyd's Register Certified, DNV GL Certified, and ABS Certified marks, along with CCC Marked, SABA Listed, NEMA Compliant, and CE Marked compliances. These certifications validate safety, performance, and conformity with regional standards, reducing risk in international projects and simplifying cross-border sourcing.
Expect periodic inspection of mounting hardware, motorized racking mechanism, and bus connections. The 237 lb unit requires appropriate lifting gear and clearances in the service area. Routine checks for continuity and mechanical operation help ensure reliable racking performance, while keeping spare trip units on hand speeds field configuration during upgrades or changes in protection strategy.
