Voltage relay PH-25t NTRN02502

Protection against voltage fluctuations and power outages

The PH-25t voltage relay is a reliable device that protects connected electrical devices from the effects of incorrect voltage in the network. Its main task is to quickly disconnect the circuit in the event of exceeding or falling below the permissible voltage values, as well as protection against a broken neutral wire. This is a key solution both for home installations and in an industrial environment where stable power supply is essential for the proper operation of equipment.

Functionality and safety

The device not only protects against damage caused by voltage fluctuations, but also offers additional functions that increase safety and facilitate diagnostics. A built-in temperature sensor disconnects the relay in the event of overheating, which minimizes the risk of fire resulting from overload or poor connections. Additionally, the relay stores information about the last five failures in an independent memory, which allows for analysis of the causes of problems and prevention of their recurrence. It displays the current voltage value in the range of 100-350V and informs about the presence of voltage at the output.

Application and installation

The PH-25t relay finds application in a wide spectrum of installations. At home, it will protect valuable devices such as refrigerators, air conditioners, heaters or computers. In industry, it can be used as a component of control cabinets, protecting machines and industrial equipment. Compact dimensions (only 2 modules) make it easy to install even in tight spaces. The housing made of self-extinguishing plastic further increases the level of safety. The device is characterized by a power reserve of the built-in relay, which translates into its long-lasting and trouble-free operation. Configuration is simple - just set three parameters to provide basic protection for devices.
