High-current, bolted contact design enables reliable switching of 1600 A circuits, reducing contact wear and extending component life, which translates to lower maintenance costs and less downtime in plant feeders. Integrated control power transformer simplifies installation by providing 120 V control power within the unit, reducing external wiring, panels entries, and assembly time for panel builders. The Arc Energy Reduction Relay and matched CTs deliver safer operation by limiting arc energy and improving protection coordination, helping facilities meet arc-flash safety targets and regulatory expectations. The top-feed, fusible configuration streamlines high-current protection, minimizing fault propagation risk and enabling straightforward integration with existing switchgear architectures. UL Listed certification, combined with compact dimensions (16 in L x 24 in W x 28 in H) and substantial weight, supports predictable field performance and procurement planning for large feeders and motor circuits.

FAQs
Installers should plan for a top-fed, fusible configuration with three-pole, three-wire wiring. Ensure adequate space for its 16 in length, 24 in width, and 28 in height and accommodate the 175 lb weight. The unit includes a control power transformer and Arc Energy Reduction Relay with matched CTs, so route control wiring and CT connections per the manufacturer’s guidelines to optimize protection coordination and ease of maintenance.
The SCB1633T120208E is rated for 1600 A, supporting heavy feeders and motor circuit protection. The Arc Energy Reduction Relay reduces fault-energy exposure during switching events, lowering arc flash risk. Matched CTs enhance fault sensing accuracy, enabling improved protection coordination. These features collectively reduce downtime while maintaining robust safety margins in high-current installations.
Yes. The unit is designed for 208 V line voltage with a 120 V control circuit, enabling seamless integration with standard plant power distributions while providing a readily available control voltage source within the switchgear assembly.
The SCB1633T120208E is UL Listed, a widely recognized safety certification for switchgear components. This certification supports compliance with safety codes and procurement standards in many industries and markets. While the data does not list CE or IP ratings, UL Listed status provides a strong baseline for safety and reliability in industrial environments.
Typical applications include main feeders and switchgear assemblies in manufacturing plants, large motors, and power distribution panels requiring high-current protection. The device’s 1600 A rating, fusible top-feed configuration, and built-in control transformer make it well-suited for centralized protection schemes where space and installation time are critical factors.
