Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: The CB1633B120208GAR delivers high fault-current capacity (1600A) to withstand large inrush events, reducing nuisance trips and protecting critical equipment in motor feeders and switchgear applications. This translates to minimized downtime and extended asset life in manufacturing lines and processing plants. The 120V control voltage ensures straightforward integration with standard control circuits and relays, enabling quick commissioning and reliable control power without custom power supplies. Bottom feed and fusible protection simplify installation in compact panel enclosures, streamlining wiring and improving service access for maintenance teams. Optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection provide flexible, code-compliant protection schemes that adapt to evolving safety standards without replacing hardware. With Kirk Provisions and Auxiliary Contact Provisions, engineers gain modularity to meet complex interlock and remote signaling requirements. The device’s NEMA compatibility (1, 3R, 4, 12) supports robust operation in damp, dirty, or outdoor environments, reducing enclosure risk and safeguarding sensitive control circuitry. A three-pole, 3-wire configuration aligns with standard industrial wiring practices, improving installation consistency and reducing commissioning errors. In practice, designers report faster troubleshooting and standardized protection across multi-panel architectures, delivering measurable reliability and uptime benefits.

FAQs
CB1633B120208GAR is designed for bottom-feed, three-pole installations in low- to medium-voltage panels. It accepts a three-wire configuration and is compatible with standard 208V control circuits. When integrating, verify enclosure space and wiring routing to maximize the bottom-feed advantage, and ensure fuse protection is matched to system demands for reliable tripping and fault isolation.
The device features a 1600A amperage rating, 120V control voltage, 208V system voltage, and fusible protection. It is UL Listed and rated for NEMA 1, 3R, 4, and 12 enclosures. The switch is three-pole with three conductors, designed for bottom-feed configurations and includes a charge-before-close mechanism for controlled, safe operation.
Yes. The unit supports NEMA ratings 1, 3R, 4, and 12, making it appropriate for indoor control panels as well as damp or outdoor-rated enclosures when installed with proper protection. Its fusible protection and robust construction help maintain performance in industrial settings, reducing corrosion risk and maintaining reliable operation over time.
Optional features include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. These options enable tailored protection strategies, simplify interlocking and signaling, and help meet specific safety or code requirements without replacing the switch core.
