Z92S4010MN/1184-MF 10UF 400 Volt, 175 Watt Metal Halide Capacitor.
Commonly used for 175 Watt Metal Halide fixtures, and works with M-57 bulbs
and a constant wattage autotransformer circuit type ballast. The case is 1.50" oval and 2.75" tall with a maximum temperature rating of 100o
C. This case has a resistor that dissipates charges to less than 50 Volts in 60 seconds when DE energized. This unit has a protective interrupter device to open the circuit at failure or the end of life.
Aerovox lighting capacitors have resistors, some resistors are internal and others are external.
Capacitors do deteriorate; stop replacing ballast kits if the transformer is good, the average life of an Aerovox capacitor is 60,000 hours
, most other brands of capacitors only average 10,000 hours. They can become weak, this is easy to check. See the Meters Section
