Decentralized drive

VLT Decentral FCD 300 drive is an all-in-one-box adjustable speed drive that can be mounted on the wall, motor, or in any standard cabinet. The NEMA 4X enclosure allows the drive to withstand detergent and high-pressure cleaning. The drive, with power range of 1/4_5 hp, 380_480-Vac, is available with a built-in disconnect switch, which eliminates drive fusing. An internal brake resistor provides precision stop, counter stop, and speed-compensated stop.

Expansion coupling

XJG-TB rigid conduit expansion coupling simplifies and speeds the job of installing expansion fittings in long runs of conduit. No disassembly during installation means no parts to drop or lose. The coupling, which requires fewer installation tools, employs an internal bonding jumper, eliminating the corrosion-prone external jumper. The UL and CSA approved coupling is available in sizes from 3/4 in. to 5 in.
