Eaton Specification Sheet - CB1633T120480A9CT5
High current rating and a 1NO-1NC contact configuration deliver robust protection. This supports uninterrupted power delivery for large motors and feeders, reducing fault dwell time and incident energy in fault scenarios. Ideal for three-pole switchgear and distribution panels in manufacturing and processing facilities. Top-feed design and fusible protection streamline wiring and field retrofit. This simplifies installation, minimizes wiring errors, and accelerates commissioning in new builds or expansions. Recommended for front-access panels and compact switchgear where space and serviceability matter. Electrical trip with a charge-before-close mechanism enhances operator safety. It reduces inrush and avoids post-trip arcing, improving life of contacts and upstream devices. Apply this in crane controls, conveyors, and other high-energy loads. 480V system voltage with 120V control voltage ensures compatibility with common plant power architectures. This enables seamless integration into existing electrical rooms and reduces the need for transformer upgrades. Works well with standard low-voltage control circuits within Eaton's Switching Devices portfolio. UL Listed certification and NEMA compatibility provide compliance and environmental resilience. The unit supports configurations up to NEMA 12 and 4 in harsh environments, with optional auxiliary contacts, ground fault, and blown-fuse detection. This translates to safer operation, easier maintenance planning, and scalable protection for growing facilities. Heavy-duty enclosure and substantial mechanical footprint withstands industrial conditions. The 175 lb weight and top-feed mounting offer stability in vibration-prone spaces, supporting reliable operation during continuous process loads.

FAQs
CB1633T120480A9CT5 uses a top-feed configuration with three terminals (1NO-1NC) and three wires. For installation, ensure the panel supports three-pole, fusible protection with enclosure ratings up to NEMA 12. Verify control voltage compatibility with 120V supplies and maintain proper clearances around the device. Optional accessories like auxiliary contacts and ground fault provisions can be added to match protection schemes and fault detection requirements.
The switch delivers a 1600A amperage rating with a 480V system voltage and a 1NO-1NC contact arrangement, enabling reliable interruption of heavy-load circuits. Its three-pole design and fusible protection minimize fault energy, while the top-feed format simplifies installation in large motor feeders and switchgear. This combination supports higher reliability and reduced downtime in industrial facilities.
CB1633T120480A9CT5 is UL Listed, providing safety certification for electrical equipment. It is compatible with NEMA-rated enclosures including 1, 3R, 4, and 12, enabling use in dusty, moist, and rugged environments. While CE or SIL certifications are not listed in the data, UL Listing plus multi-NEMA compatibility covers common regulatory and environmental requirements for industrial installations.
Yes. The catalog notes indicate optional Ground Fault Relay and Blown Fuse Detection can be configured, along with auxiliary contact provisions. These options improve fault detection, safety, and maintenance planning. When selecting add-ons, ensure compatibility with the 1NO-1NC configuration, top-feed wiring, and enclosure size to preserve proper clearance and serviceability.
The product carries Eaton’s warranty policy 25-000, offering one year from the date of installation or eighteen months from shipment, whichever occurs first.
