Power Relays, Over 2 Amps – PT380524 Application Field and Working Principle

PT380524 is a powerful two-amp AC-DC-AC solid-statecomposite relay and is designed for applications in the power transmissionand distribution industry. It is mainly used to protect to protect powercircuits against all types of overvoltage and thermal overloads. The PT380524is capable of providing effective protection with minimum interruption time.

Application Field

The PT380524 is mainly used in the power transmission and distribution industry,having a wide range of applications including:

• High Capacity Power Protection: The PT380524 is used in high voltage power lines with capacities up to two amps in order to protect against sudden changes in power. It can also detect and switch off overloaded lines before damage occurs.
• Protection of Power Transmitting Equipment: The PT380524 is used in power lines that carry high power transferences such as transformers and electrical motor-generators. It helps to protect these electrical devices against any interference.
• Thermal Overload Protection: The PT380524 is designed to detect and switch off overloaded lines before any possible damage occurs. By detecting the overheating of the line, it can immediately switch off the line to protect against any damage.
• Fault-protected Power Lines: The PT380524 is used in power lines carrying electrical signals or current to detect any faults in the lines and switch them off before any damage occurs to the power line.

Working Principle

The PT380524 operates on a two-phase principle, which means that it iscapable of detecting sudden changes in power and can shut offoverloaded lines quickly before any damage can occur. The PT380524works by detecting an unexpected electricity surge (the first phase) andthen shutting off the power supply before the surge can reach
