Eaton CB1633B120480A95 Pringle bolted switch - UL Listed

Feature → Business Impact → Application: The CB1633B120480A95 employs a pringle bolted pressure contact switch design that delivers robust mechanical integrity and rapid electrical trip, reducing outage duration and wear on circuit interrupters when protecting large three-pole circuits in 480 V systems. This translates to improved uptime for critical manufacturing lines and safer, more predictable protection coordination in switchgear assemblies. Application: suitable for heavy-duty power distribution where 1600 A capacity and a bottom feed configuration are required, such as mining, metals processing, and large OEM installations. Feature → Business Impact → Application: The unit offers 1 NO-1 NC contact configuration with fusible protection, enabling precise control and selective tripping to minimize disruption during maintenance or fuse events. Application: ideal for industries prioritizing fault isolation and minimized arc-flash exposure in high-current environments. Feature → Business Impact → Application: Control voltage rated at 120 V supports compatible control circuits and reduces wiring complexity, while the 480 V system rating ensures seamless integration with common industrial power rails. Application: fits standard plant electrical rooms and panel boards requiring reliable three-pole operation. Feature → Business Impact → Application: Optional ground fault relay, blown fuse detection, single-phase protection, Kirk provisions, and auxiliary contact provisions provide flexible protection schemes, improving uptime and diagnostic capability. Application: beneficial for facilities pursuing enhanced safety compliance and easier maintenance diagnostics. Feature → Business Impact → Application: Bottom feed and bottom fuse configuration simplify installation in existing panels and retrofit projects, reducing labor and field modifications. Application: supports retrofit of aging switchgear where cable routing and footprint constraints are critical. Feature → Business Impact → Application: UL Listed certification and NEMA ratings (1, 3R, 4, 12) give documented safety and environmental resistance, easing regulatory approvals and procurement vetting. Application: suitable for harsh industrial environments, outdoors in protected enclosures, and inside rugged electrical rooms.
