Front terminal fixed four pole design simplifies wiring and reduces panel space, enabling faster assembly and safer service with minimal custom wiring. Business impact: reduced installation time and fewer wiring errors in switchgear and control cabinets; applicable to data centers and manufacturing lines where space is at a premium. 320 A nominal current with Ics up to 200 kA at multiple voltages provides robust fault clearing for transformers and large machines. This translates to higher uptime and improved process reliability in process facilities and utility interfaces. Rated insulation voltage of 1000 V and impulse withstand voltage of 8 kV support reliable insulation in varied distribution environments, lowering the risk of insulation failure during transients. Energy losses are kept to 13.6 W per pole under rated conditions, reducing cabinet heat and cooling requirements in continuous duty applications. With mechanical durability of 20000 cycles and electrical durability of 7000 cycles, you gain predictable lifecycle performance with lower maintenance intervals. The device is RoHS and REACH compliant, with CMRT and TSCA declarations, easing cross market procurement and regulatory reporting. Compatible with the Tmax T5 family and installation instructions for front terminals, it integrates with existing panels and allows for streamlined stocking, standardizes panel design, and minimizes training needs for maintenance teams.
