Abstract:
An apparatus and method for selectively automatically resetting an electronic protection device. The electronic protection device may protect a motor load by disconnecting the load from a power source when the current drawn by the load exceeds a threshold, when the power source suffers from a phase imbalance or phase loss, or when another condition is detected. The electronic protection device discriminates between different types of fault conditions and determines whether to suppress an automatic reset function of the device. The electronic protection device includes a reset energy storage device for automatically resetting the electronic protection device following a trip event using energy from the reset energy storage device. In operation, the electronic protection device detects a fault condition not calling for an automatic reset, then discharges the reset energy storage device and trips the electronic protection device before the reset energy storage device recharges.
