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.
All 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
