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
