Motor Starters
Motor starters are devices that connect an electric motor to the mains and disconnect it and manage its start, combining a contactor with overload protection or a semiconductor power stage in a single housing. They are used on pump, fan, compressor and conveyor motors at feeders that need direct, forward-reverse (reversing) or soft starting. The category includes Schneider Electric TeSys LE and ABB DRAS enclosed starters, ABB PSE and PSTX soft starters, and Siemens 3RM1 and 3RK1308 motor starting hardware; thermal setting ranges such as 2.6-3.7 A, 8-11.5 A and 12-16 A and coil voltages such as 220 V AC and 380 V AC are examples for the enclosed types. Before selecting, clarify the motor's rated current and power, the starting type (direct, forward-reverse or soft), the control voltage, whether the start is made loaded or unloaded, and the required communication interface. For soft starters, communication adapters such as DeviceNet are listed as separate products. A soft starter only softens start and stop and does not provide continuous speed control; it does not replace a frequency inverter.

How to choose Motor Starters
Motor starters are devices that connect an electric motor to the mains and disconnect it and manage its start, combining a contactor with overload protection or a semiconductor power stage in a single housing. They are used on pump, fan, compressor and conveyor motors at feeders that need direct, forward-reverse (reversing) or soft starting.
- Separate overcurrent/leakage protection, motor starting and local isolation requirements.
- Select rated current, pole count and breaking capacity (kA) from the installation calculation.
- Match coil voltage, auxiliary contacts and tripping curve to the control circuit and load type.
