Protection relays and systems are an essential component of the power system, providing ancillary services and protecting equipment from overloads and other faults. The MPS-469X-04000 is a protection relay and system designed for a specific application, providing comprehensive fault protection in industrial settings. Here we discuss the application field and working principle of the MPS-469X-04000.

The MPS-469X-04000 is a three-phase overcurrent and earth fault relay suitable for use in industrial settings. It can be used for monitoring and controlling linear loads, transformers and motors. Its power supply is low voltage AC and its rated frequency is 50 Hz or 60 Hz. The C-T contacts, RCBO and Infrared I/O structure enable easy installation and maintenance.

In terms of application field, the MPS-469X-04000 can be used to protect AC power systems from faults such as short circuit, ground fault, under-voltage, over-current and over-voltage. It is suitable for use in various industrial systems, such as distribution systems, motor control systems, UPS systems, electrical substations and switchgear. The protection system can also be used in combination with energy management systems, providing comprehensive protection for power systems while ensuring energy efficiency.

The working principle of the MPS-469X-04000 is based on the principle of over-current detection. In normal operation, a reference current flows through the relay, which is compared to the actual current. If the actual current is greater than the reference current for a pre-determined amount of time, the relay trips and the protection circuit of the system is activated. The MPS-469X-04000 also includes numerous protection functions, such as built-in self-test, short-circuit protection, thermal overload protection, over-voltage and under-voltage protection, and adjustable delay and current settings.

In conclusion, the MPS-469X-04000 is a protection relay and system designed for a specific application field. It is suitable for use in different industrial settings and provides comprehensive fault protection in AC power systems. Its key working principle is overcurrent detection, based on the comparison of the reference current and the actual current. It also includes numerous protection functions for enhanced safety and reliability.
