Motor Protection Relay MDB-201Z Overload Current Unbalance and Phase Loss Protector for Pump Motor 2-99A

Why Choose the Motor Protection Relay
The motor is easier to burn the winding than in the past. It is due to the continuous development of the insulation technology. In the design of the motor, it is required to increase the output and reduce the volume, so that the heat capacity of the new motor is smaller and the overload capacity is weaker. Moreover, due to the improvement of the degree of production automation, the motor is often required to operate frequently in various ways such as frequent starting, braking, forward and reverse rotation, and variable load, which puts higher requirements on the motor protection device.

The application of the motor is wider. Often used in extremely harsh environments, such as humidity, high temperature, dust, corrosion and other occasions. Coupled with the irregularity of motor manufacturing, the omission of equipment management. All of this has caused today's motors to be more susceptible to damage than in the past, especially overload, short circuit, phase loss, broom and other faults.

The Reason of use Motor protection Relay

It is not uncommon to cause motor burns or even cause major safety accidents during use. According to incomplete statistics, the amount of electricity consumed by motor burns in the country is tens of millions of degrees per year, and the number of motor burns is more than 200,000 times. The damage caused is a huge amount that cannot be estimated. Therefore, it is important to make the motor protector have significant energy saving, improve production efficiency and economic benefit, and ensure safe production.
