Electrical
Rated at 20 amperes at lamp voltage shown below.
Dielectric: withstanding voltage exceeds 1500 volts. All
fuseholders are supplied with a resistor. When designing
indicating type fuseholders into a circuit, consideration
should be given to the resistance of fractional amperage
fuses and the parallel resistance of the indicator lamp
and 7its resistor.
Mounting
Withstands 15 lb.-in. mounting torque. Maximum panel
thickness is .250”.
Molded Parts
Black Body and knob are thermoset (UL94 V-0), except
lens is thermoplastic (UL 94HB). See Table below for lens
color.
Knob Bayonet style.
Terminals Copper & copper alloy. Tin plated.
Ambient
Temperature
–40ºC to +85ºC.
Hardware
Neoprene washer, lockwasher & hex nut
unassembled. O-ring option available must
be ordered separately using part number 901-108.
