Terminal options
SPEAR single-phase reclosers can be specified with eyebolt
terminals (400 A , 630 A, and 800 A), two-hole (400 A,
630 A) or four-hole (800 A) flat-pad terminals, or stud-type
terminals (400 A, 630 A, and 800 A).
The eyebolt, flat-pad, and stud terminals are made of
copper alloys. Eaton recommends terminal connection
to copper wires to optimize the electrical connection.
Aluminum cables may produce aluminum oxide sufficient to
compromise the electrical connections.
Anti-oxide coatings for temporary protection of wire-
brushed, aluminum cable connections to flat-pad or stud
terminals must be maintained at intervals determined by
the customer based on load current, climate, and other
installation conditions.
Copper conductors only are recommended for eyebolt
terminals.
Mounting hangers
Crossarm mounting hanger
A crossarm mounting hanger is available for crossarm
installation. These are available in sets of two; one set is
needed for each SPEAR single-phase recloser. To order this
accessory, specify part number KA39H2.
Pole-mounting accessory
The 15 kV and 27 kV SPEAR single-phase reclosers can
be directly mounted to the pole using the built-in tank
mounting channels for BIL rating of 125 kV and lower. Due
to electrical clearances, the pole-mounting hanger accessory
is recommended for mounting either the 27kV (with 150 kV
BIL accessory), or 38 kV (170 kV BIL) SPEAR single-phase
recloser to the pole. To order this accessory, specify part
number KSPR-364.
