Eaton Specification Sheet - CB1633B120208GRAR
Feature → Business Impact → Application: The CB1633B120208GRAR delivers a 1600A amperage rating in a three-pole, fusible design, enabling robust protection for heavy motor feeders. The bottom feed configuration simplifies panel layouts and reduces field wiring complexity, cutting installation time and potential connection errors in switchgear assemblies. Feature → Business Impact → Application: Single-phase relay with capacitor trip device (SPVR) and BFD with three normally off lights (trips device) provide coordinated, fast protection with clear trip indication, reducing the risk of extended outages and easing diagnostics in motor control centers. Feature → Business Impact → Application: Ground fault with control power transformer support and optional Ground Fault Relay and Blown Fuse Detection extend protection to modern safety standards, enabling rapid fault detection and simplified maintenance in critical feeders. Feature → Business Impact → Application: 208V system voltage and 120V control voltage, with NEMA ratings of 1, 3R, 4 and 12, ensure compliance across indoor and outdoor installations and simplify compatibility with existing low-voltage switchgear. Feature → Business Impact → Application: Bottom feed, three-wire, three-pole design and Kirk/Auxiliary provisions (where available) offer installation flexibility and future-proofing for panel upgrades or retrofits in industrial facilities. Feature → Business Impact → Application: Fusible protection adds a traditional layer of overcurrent protection, supporting reliable coordination with downstream protection schemes and reducing the probability of cascading faults in power distribution networks.

FAQs
CB1633B120208GRAR is designed for three-pole, bottom-feed installations and works with Eaton low-voltage distribution panels that require fusible protection and ground-fault capability. It supports 208V system operation and 120V control voltage, making it suitable for retrofit projects in existing switchgear where SPVR protection and auxiliary contact provisions are desired.
The SPVR provides a capacitor-assisted trip signal, enabling a more reliable and faster release under fault conditions. This reduces the duration of fault current flow, helps coordinate with downstream protection, and lowers the risk of arc-flash events in motor feeders and power distribution panels.
Yes, the CB1633B120208GRAR is UL Listed. It carries NEMA ratings of 1, 3R, 4 and 12, allowing dependable performance in a range of indoor and outdoor environments, from simple enclosed panels to harsh industrial atmospheres.
Key ratings include 1600A amperage, 208V system voltage and 208V voltage max, with a 120V control voltage. It is fusible-protected and features ground-fault capability with transformer supply, supporting three-pole, three-wire configurations for robust motor protection.
By reducing nuisance trips through SPVR coordination, enabling reliable ground-fault detection options, and simplifying installation with bottom-feed geometry, operators can lower unplanned downtime, improve maintenance scheduling, and extend panel life in high-load environments. Optional accessories like Ground Fault Relay and Blown Fuse Detection further enhance protection and uptime.
