Accessories
Auxiliary switch
A three-stage auxiliary switch can be provided as an accessory.
Each stage has two independent contacts that permit any desired
combination of “a” (follow state of recloser contacts) and “b”
(opposite recloser contacts) positions. The switch contacts are
insulated for 600 V and have a continuous current rating of 10 A.
Their interrupting ratings are shown in Table 7.
Terminals
The standard terminal is a 2-hole flat-pad terminal rated 630 A. An
eyebolt, 1/0–500 mcm (630 A), eyebolt 4/0–1000 mcm (800 A), and
4-hole flat-pad terminals, are available as an accessory (see Figure
17).
The eyebolt and fixed-pad terminals are made of copper alloys.
Cooper Power Systems recommends terminal connection to
copper wires to optimize the electrical connection.
Anti-oxide coatings for temporary protection of wire-brushed
aluminum cable connections to flat-pad terminals must be
maintained at intervals determined by the customer based on load
current, climate, and other installation conditions.
Eyebolt terminals are recommended for copper conductors only.
Pole-mounting hanger
A pole-mounting hanger (see Figure 17), which bolts directly to the
recloser frame, is available for pole-mounting installation.
