Eaton's Cooper Power series NOVA STS single-tank triple-single recloser consists of three single-phase recloser units in one tank. Each consists of an interrupting module, with embedded CT and mechanism. The interrupter modules utilize outdoor cycloaliphatic-epoxy-encapsulated vacuum interrupters. Suitable for pole or substation mounting, the NOVA STS recloser provides automation of distribution feeders in line applications. The three NOVA STS recloser units are controlled by a single Form 6 recloser control, on a per-phase basis for both source and load that can be programmed for three operating modes.
