Nulec U-series

> Services

 
U-Series three phase pole mounted auto recloser or circuit breaker uses the latest technology in solid dielectrics (hydrophobic cycloaliphatic), vacuum interruption and insulants. This device does not use any gas or oil insulants. Instead, cyclo-aliphatic epoxy bushings are used to insulate the vacuum interrupters. This type of construction results in to a lightweight unit. The design has been optimized for automation, remote control, and monitoring applications and has built in current and voltage sensors for measurement and data logging.
