How Are Shihlin Magnetic Contactor Models Different? Choose the Right Series for Motor Control
In industrial motor control systems, a magnetic contactor is used to switch a motor’s electrical circuit on and off, allowing the motor to start and stop safely. It can operate together with various control devices, including push buttons, relays, PLCs, and factory automation systems.
Shihlin Electric offers magnetic contactors in a wide range of sizes and configurations to support different applications, from compact machine control systems to high-power industrial motors. The product range includes magnetic contactors, magnetic switches, non-reversing and reversing models, as well as accessories for motor control systems that comply with international standards.

How to Select the Right Magnetic Contactor
When selecting a magnetic contactor, consider the motor specifications, electrical system, and required control configuration. Review the following key factors:
- Motor power rating: Check the motor output in kW or HP.
- Operating current: Select a rated current suitable for the connected load.
- System voltage: Confirm the voltage used in the main power circuit.
- Coil voltage: Select a coil voltage that matches the control circuit.
- Control configuration: Determine whether a non-reversing or reversing arrangement is required.
- Required accessories: Consider thermal overload relays, auxiliary contacts, mechanical interlocks, and surge absorbers.
Selecting a contactor that matches the motor rating and control system will help improve operating efficiency, reliability, and safety.
