What is MPCB?
The Motor Protection Circuit Breaker (MPCB) is a very important device to protect motors from problems that may occur due to overload or short current. It also has devices that have additional features such as protection against voltage drops or falling visas.
MPCB Working Principle
This device has Bi-Metallic Strips to protect the engine if there is an overload, and it also has magnetic coils to protect the motor from short-current. If there is an increase in current, the heat generated by the large current by letting the thermal coils expand, which leads to the separation of the supply from the motor to protect it.
Features of MPCB
- Overload protection.
- Short Circuit Current protection.
- Phase Loss protection.
- Under Voltage protection.
- It can be connected directly to the engine or via a contactor.
- The engine efficiency improves and reduces the likelihood of sudden failures.
How to use the MPCB?
This device is adjusted according to the full load current of the motor, which means that we must know the power of the motor in order to adjust the device correctly.
Manufacturers of MPCB
- Siemens and
- ABB
which are characterized by high quality & excellent performance.
If you have an electric motor, make sure you have a suitable MPCB installed to protect it from malfunctions that may occur due to short-circuit or overload.
This will help keep the engine for as long as possible and reduce costly breakdowns.
