Product Details
Springer Controls manufactures a complete line of IEC enclosed AC motor starters up to 60HP or 80A. Assembled motor starters consist of a contactor, overload relay, and a NEMA 4X rated polycarbonate enclosure. To select the proper starter for your requirements, refer to the motor or equipment nameplate to verify the full load amperage (FLA) at the input voltage you will supply, and confirm whether it is 1-phase or 3-phase power to the motor. Choose a starter rated for current (amps) higher than the FLA of your motor, select the control power used to close the contactor, and choose the overload by selecting a current range that contains the FLA of the motor. Optional criteria for selection include the type of incoming power: if line power will be used as the control power as well, this is referred to as a "direct-online starter"; if the control voltage differs from the line voltage, this is termed "separate control voltage." If the starter needs to be activated from an external switch, terminals can be added to accept the control power input from that switch, known as "remote start terminals." If remote start terminals are desired and different voltages are used for line power and control power, it is referred to as "separate control voltage + remote start terminals." The key features include a 38A 3-phase direct online reset button only, a 100-250V AC/DC coil, and a 24-29A overload in a NEMA 4X polycarbonate enclosure.
