SPECIFICATIONS:
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.
