Model 295-Capacitor Trip Device www.time-mark.com
is less than 5 milliamps. The capacitor holds sufficient charge to trip the breaker for at least 12 seconds after the charging voltage is removed. However, on most fault conditions, some voltage is still present, so the Model 295 is designed so that 65% of normal voltage gives sufficient charge to trip the breaker. A low-energy lamp, connected in parallel with the storage capacitor, gives a visual indication when the voltage charge is 85 volts or more on the 120V version and 170 volts or more... (read more)
