Eaton Specification Sheet - CB1633T120208RCT
High amperage rating with SPVR protection enables a compact, single-device solution for feeders up to 1600A, reducing conductor and enclosure count while delivering safer starts and trips. This translates to measurable downtime reduction and improved reliability in manufacturing lines and process controls. The 208V system voltage and 120V control voltage simplify integration with standard plant electrical infrastructure, lowering wiring complexity and facilitating quicker panel upgrades. Top feed and fusible protection streamline installation, facilitate clear fault isolation, and support easy retrofits in existing switchgear. The three-pole, three-wire configuration provides balanced protection across phases, improving coordination with upstream breakers and downstream motors. UL Listed certification reinforces safety compliance, while optional features like Ground Fault Relay or Blown Fuse Detection address stricter protection regimes and predictive maintenance needs. Industry-grade enclosure compatibility (NEMA 1, 3R, 4, 12) helps you select the right protection level for harsh environments and wet or dusty plant areas. Suitable for control power transformers and SPVR-enabled protection, this unit is well-matched to modern automation architectures and retrofit projects.

FAQs
This model uses a top-feed configuration with three wires and is designed for three-pole operation. Ensure adequate clearance for a 28 in tall unit, correct wiring for 208V system voltage, and compatible enclosure (NEMA 1, 3R, 4, 12). Include proper control-circuit grounding and verify capacitor trip device (SPVR) integration with the control transformer. Frame-mounted mounting provisions and available auxiliary contacts can simplify retrofit in existing panels.
CB1633T120208RCT is rated for 1600A with a 208V system voltage and 120V control voltage. It supports fusible protection and a single-phase SPVR capacitor trip device. The device’s three-pole, three-wire arrangement ensures balanced phase protection, making it suitable for large-scale 208V distribution panels, switchgear, and motor control centers in industrial facilities.
Yes, the unit is compatible with rugged environments thanks to its NEMA ratings—1, 3R, 4, and 12—providing enclosure protection against dust, water, and corrosion in typical factory settings. UL Listed certification further supports compliance in safety-critical installations. For extreme locations, pair with enclosure gaskets and proper mounting to maintain protection levels around high-current feeders.
The CB1633T120208RCT carries UL Listed certification, indicating compliance with recognized safety standards for electrical equipment. While SIL, CE, or IP ratings are not listed in the datasheet, the product’s UL certification plus its NEMA enclosure compatibility helps meet common industrial safety requirements and supports installation in a wide range of U.S. and international facilities where UL compliance is mandated or preferred.
Maintenance benefits come from integrated protection features such as the SPVR capacitor trip device and optional detection options, which reduce nuisance trips and unplanned downtime. The high current rating and robust enclosure compatibility lower replacement frequency and spare parts cost for large feeders. Over the asset life, customers typically experience improved uptime and lower total cost of ownership due to safer, more reliable switching in critical power paths.
