We present to your attention an updated range of PH series voltage relays for home and industrial use. The voltage relay is designed to protect electrical equipment from unacceptable mains voltage fluctuations and the consequences of a neutral (zero) break.

The voltage relay:

• disconnects the electrical circuit if the voltage goes beyond set limits
• displays the actual voltage value at the input contacts in the range of 100 V to 350 V and shows the presence of voltage at the output contacts
• stores information about the last five incidents in non-volatile memory

The voltage relay is protected against overheating and will disconnect the load if the internal temperature exceeds 85°C (due to exceeding the rated load current, poor contact from weak terminal screw tightening, etc.).

Advantages:

• overheating protection as an additional fire safety factor
• event log
• compact size (only 2 modules)
• self-extinguishing plastic
• power reserve of the built-in relay

Application area:

• household use: protection for the entire home or individual devices, such as refrigerators, air conditioners, heaters, computers, etc
• industrial use: as part of a control and switching panel; as a component of equipment such as an industrial refrigerator, machine tool, etc

Key features:

• overheating protection – provided by a built-in temperature sensor, it will disconnect the relay in case of overheating of the device’s internal components
• event log helps identify weak points in the electrical network
• easy and simple setup – setting only 3 parameters ensures protection of your devices from major network faults
