Voltage relay PH-40tc NTRN04002

Voltage fluctuation and power failure protection

The PH-40tc voltage relay is a reliable device that will protect your electrical installation and connected devices from the effects of incorrect voltage in the network. Designed for both domestic and industrial applications, it ensures uninterrupted power supply and minimizes the risk of equipment damage. Thanks to its compact size (only 2 modules) it is easy to install in a distribution box.

Functionality and safety

The device not only interrupts the circuit when the voltage exceeds or falls below the set values, but also offers a range of additional functions to increase safety and facilitate diagnostics. The display shows the current input voltage and the status of the output contacts, and the built-in memory stores information about the five most recent failures, allowing for quick identification of problems in the installation. In addition, the relay has thermal protection – it disconnects the load in case of overheating, which minimizes the risk of fire caused, for example, by loose connections or overload.

Applications and benefits

The PH-40tc relay will be useful in many situations:

• Home protection: protecting the entire electrical installation or individual devices (refrigerator, air conditioning, computer, heater) from damage caused by voltage fluctuations.
• Industrial protection: installation in control cabinets and switchgear as a protective element for industrial machines and equipment.
• Fault log: Allows analysis of the causes of power outages and prevention of their recurrence.
• Compact size: Enables easy installation even in tight distribution boxes.
• Thermal protection: Protects against overheating and potential fire hazard.
• Self-extinguishing plastic: Increases safety of use.

The device is designed to operate with a voltage of 230/240 AC and has a maximum current load of 40A (9kW). Parameter adjustment is done using knobs, which provides simple and intuitive configuration. Thanks to this, the PH-40tc relay is a comprehensive solution for anyone who cares about the safety of their electrical installation and the protection of valuable equipment.
