Overload relays are specifically designed to protect CEM motor contactors from overloads and phase failures. These devices monitor the current flowing to the motor and interrupt the circuit if the current exceeds a safe limit, preventing the motor from overheating. The CEM series is designed to work seamlessly with ETI's range of bimetal overload relays, providing comprehensive motor protection. These overload relays conform to international standards, ensuring reliable and safe operation of your motor control systems.
