Abstract
A electronic motor protection system is shown having a power supply (12) usable with multivoltage supplies and providing protection from over-temperature conditions caused by various fault conditions. The system also has optional features of a time delay (20) for re-energization and for low voltage protection (22). The system is mounted on a circuit board and encased in potting material which also locks two housing parts together (30, 34). A miswiring feature is also provided to prevent connecting line voltage to the control circuit or sensor terminals.
