Cooper Power Systems NOVA 15 - Ratings and Specifications; Check Recloser Ratings Prior to Installation

Check Recloser Ratings Prior To
Installation
The recloser must be applied within its specified ratings.
Check data plate ratings and compare with the system
characteristics at the point of application prior to installa-
tion. Tables 1, 2, 3, and 4 list the ratings and specifications
for the Type NOVA recloser. Table 5 lists the auxiliary-
powered interface power requirements.
