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 its resistor.
Black thermoplastic body (UL94 V-0). Thermoplastic
bezel, cap and lens (UL94 V-2). See tables below for
colors.
Non-indicating: –40ºC to +85ºC. Indicating: –40ºC
