Contactors are designed to handle high-current loads, while relays are suitable for low to medium-current loads. This difference in load capacity results from the design and construction of the devices, with contactors featuring larger and more robust auxiliary contacts to accommodate higher currents.

Relays are generally used for lower-power applications and can switch multiple contacts simultaneously. They are suitable for controlling small electrical loads. Conversely, contactors are designed to control high-power circuits and are typically used in industrial applications.

Motor protection relay that protects your motor against burnout. Can be used as protection against motor burnout during overload or locked rotor, and offers a wide range of specifications to meet various needs, including protection against overload and phase loss, time lag, quick connect, etc.
