454001R1 - S&C Electric 34.5 kV SMD-1A Slow Fuse for Outdoor Distribution

454001R1

454001R1 is a 34.5 kV SMD-1A slow fuse designed by S&C Electric for outdoor distribution applications.

This fuse provides reliable, high-speed fault interruption with a slow-blow characteristic suitable for transformer protection and other substation uses. It features a solid-material-lined bore that enables fast arc elongation and efficient deionizing gas action, ensuring positive fault clearing. The fuse is part of the SMD series, rated for 34.5 kV nominal voltage, and is engineered to handle continuous currents up to 200 amperes with an interrupting rating suitable for typical distribution system fault currents. It mounts using standard hardware compatible with terminal pads and is designed for use in solidly grounded-neutral systems.
