FTDF Fused Sectionalizer Pad-Mounted Switchgear
The Federal Pacific FTDF is a dead-front fused sectionalizer pad-mounted switchgear designed for radial and loop feed underground distribution systems requiring load-break elbow switching with fuse protection on laterals and taps. The low-profile enclosure is engineered to present the lowest possible silhouette while maintaining ample operating and electrical clearances.
Available at 15kV and 25kV in single-phase and three-phase configurations, the FTDF is available with either general-purpose current-limiting or expulsion-type power fuses to match the specific protection requirements of each application.
Technical Overview
The FTDF enclosure is designed for long service life in outdoor environments with a rugged, tamper-resistant construction meeting the stringent security requirements of ANSI C57.12.28.
- 15kV and 25kV class, available in single-phase and three-phase configurations.
- Dead-front load-break elbow switching of radial and loop feed systems.
- Non-load-break fuse protection on laterals and taps with current-limiting or expulsion-type power fuses.
- All-welded 11-gauge steel construction for additional strength and rigidity.
- High-quality steel with corrosion-resistant hardware and epoxy powder primer with baked powder topcoat finish.
- Flush door handle with padlocking provisions and penta-head security bolt with three-point latching system.
- Ventilation louvers of baffle and screen construction allow air circulation while preventing insertion of foreign material.
