And electronic motorprotectionrelay is used to protect the motor completely.
应用电机保护继电器实现了对电机的全面保护。
2
Increase external overload protection is to prevent motor burned effective means, such as thermal relayprotection.
增加外部过载保护是防止电机烧毁的有效手段，如热继电器保护。
3
Temperature relay tests temperature of motor, if it exceeds rating temperature to send a signal, contactor cut off main circuit to complete protection of motor.
