Selection and application
Match the starter class, type and size, the motor nameplate full-load current, and the required number of thermal units. The heater number is not a universal motor-amp rating. Current ranges vary between Schneider selection tables and between one- and three-thermal-unit installations. Match the existing part only after confirming it is correctly selected for the motor. This is a heater element, not a complete overload relay or short-circuit protective device.
