Additional information

These instructions can not cover all details or variations in 

the equipment, procedures, or processes described nor 

provide directions for meeting every possible contingency 

during installation, operation, or maintenance. For additional 

information, contact your Eaton’s Cooper Power series 

product representative.

Acceptance and initial inspection

Each recloser is completely assembled, tested, and 

inspected at the factory. It is in good condition when 

accepted by the carrier for shipment. Upon receipt, inspect 

the shipping container for signs of damage. Unpack the 

recloser and inspect it thoroughly for damage incurred 

during shipment. If damage is discovered, file a claim with 

the carrier immediately.

Handling and storage

Be careful during handling and storage of the recloser to 

minimize the possibility of damage. If the recloser is to be 

stored for any length of time prior to installation, provide a 

clean, dry storage area.
Eaton recommends transporting the Cooper Power series 

NOVA reclosers in the closed position to maximize the 

operational performance of the unit.

Description

The NOVA 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 on an 

aluminum or stainless steel tank. The tank is suitable for 

pole or substation mounting. The interrupter modules 

utilize outdoor cycloaliphatic-epoxy-encapsulated vacuum 

interrupters.
The three single-phase reclosers that make up the NOVA 

STS recloser are 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
