NOTE: The 20 ampere single pole holder is designed to
accept all fuse ratings up to 20 amperes.
20 ampere fuseholders should be spaced 12.7mm (0.50”)
apart when loaded to maximum capacity, center to center
to insure proper heat dissipation under normal operation.
Heatsinking may be required for operation in higher
ambient temperatures or alternate configurations.
All terminals dimensions should be taken with fuse
installed.
