Description
The NOVA NX-STS single-tank, triple-single recloser
consists of three single-phase reclosers in a single tank.
Each recloser consists of an interrupting module, with an
embedded current transformer, and mechanism mounted
to an aluminum head casting. The thermoset polymer tank
enclosure is suitable for pole or substation mounting and is
corrosion resistant. The interrupter modules utilize outdoor
cycloaliphatic-epoxy-encapsulated vacuum interrupters.
The NOVA NX-STS recloser is controlled by a single
microprocessor-based recloser control that can be
programmed for three operating modes:
•
Single-phase trip, single-phase lockout
•
Single-phase trip, three-phase lockout
•
Three-phase trip, three-phase lockout
