MPCBs are commonly used in industrial and commercial electrical systems and have adjustable capabilities to protect against various currents and heats.
Function of MPCB Thermal Overload Relay
The main function of the MPCB thermal overload relay is to protect electrical circuits from excessive current and heat. When electrical circuits experience failure and damage due to excessive current or heat, the MPCB thermal overload relay automatically cuts off the electric current to protect the circuits from serious damage. In this way, the MPCB thermal overload relay acts as a protective device for electrical circuits, preventing harm and damage to these circuits.
The MPCB Thermal Overload Relay (Motor Protection Circuit Breaker) is a type of electrical circuit protector that uses a thermal mechanism to allow circuits to automatically disconnect and connect when the temperature increases.
The primary application of Schneider’s MPCB Thermal Overload Relay is in electrical circuits requiring protection for motors and other electrical components. For example, in circuits using electric motors, the MPCB thermal overload relay is used as a circuit protector to safeguard the motor against temperature increases and current leaks. Additionally, the MPCB thermal overload relay can be used in circuits requiring protection for electrical systems, such as safety systems.
