Specifications
Pitch—0.75” [19.05] centerline, 16 circuits per foot
Voltage Rating—Blocks meet 600 volt creepage and clearance requirements of
NEMA, UL and CSA for general industrial control equipment and panelboards.
Withstand voltages greatly in excess of IEE switchgear standards for 750 volts.
Fuse Size—Any 13/32 x 1-1/2 in. [10.32 x 28.10] ferrule type cartridge fuse up to
25 amps, indicating or non-indicating, which meets Mil. Spec. F-15160.
