Voltage relay PH-240t NTRN240T2

Device Protection and Precise Measurement with PH-240t

The PH-240t voltage relay is a reliable device designed to protect sensitive electrical equipment in homes and industrial plants. It protects against the effects of voltage fluctuations in the network and neutral wire breaks, which is particularly important for devices such as refrigerators, air conditioners, washing machines, or audio-video equipment. The device is adapted to a load of up to 40 A, making it a universal solution for many applications.

PH-240t is not only protection – it is also advanced measurement. It displays the current network voltage and the status of the output contacts, informing about the load status. Additionally, it measures and displays on the display the current drawn by the connected devices, active and reactive power. In the event of exceeding the set current or power thresholds, it automatically disconnects the load, preventing damage. Built-in thermal protection protects against overheating in the event of an overload.

Functionality and Versatility

The PH-240t relay can function as:

• Voltage relay: basic protection against network irregularities.

• Power limit relay: control of energy consumption and prevention of overloads.

• Digital multimeter: displaying key network parameters (voltage, active power, reactive power, current) – a useful diagnostic tool for installers and users.

The device has a memory for the last five failures, which facilitates analysis of the causes of problems and quick diagnosis of faults. Mounting is done on a DIN rail, which ensures easy installation in the distribution board.

Construction and Operating Parameters

PH-240t is powered directly from the power circuit of the protected device. This ensures independent operation and eliminates the need for additional power sources. The durable housing made of self-extinguishing plastic ensures safe use. The device meets EN 50160 standards regarding power quality. Thanks to its compact dimensions (2 DIN – 36 mm wide), it easily fits into any distribution board. The ability to adjust the trigger thresholds allows you to adapt the device to the specific needs of the installation and protected equipment.
