Home ProductRated Voltage Adjustable Relay
The 3 Phase Motor Protection Relay is a circuit control element. It can break the contacts of switching appliances in time to protect the motor quickly and reliably when the main circuit of the motor is in abnormal working conditions such as phase break, overload, three-phase unbalance, etc. Our products are designed for rail mounting and are easy to operate. The 3 Phase Motor Protection Relay is available in a wide range of rated voltages with different specifications.
Features
The excellent quality of our 3 Phase Motor Protection Relay and warm and thoughtful service make us win the trust of customers. It is carefully designed with a small size to save space. Also, it is simple in structure, easy to use, and reliable in operation. And it has the advantages of no power consumption, long life, and no arc generation during operation, so it is an ideal electrical product for motor protection.
