Tomzn Tovpd1-60-ec Manual

: The "EC" in the model number suggests compliance with certain European standards or regulations, possibly indicating that the device meets specific requirements for safety, electromagnetic compatibility, or environmental protection.

The TOMZN TOVPD1-60-EC is a multi-functional, adjustable protective device designed to safeguard single-phase electrical systems against unstable voltage conditions and overcurrent events. This device integrates an over-voltage protector, under-voltage protector, and over-current protector into a single compact DIN-rail module.

Integrate a standard miniature circuit breaker upstream. This protection relay provides over-current threshold limitation but lacks the magnetic-trip physical design necessary to halt dead short-circuits safely. 2. Terminals Configuration

: It likely offers protection across multiple modes, including line-to-line, line-to-ground, and line-to-neutral, providing comprehensive protection against various types of surges. tomzn tovpd1-60-ec manual

Setting the undervoltage value to "Lo" (or under 140V) closes the undervoltage function.

Solar inverters can be damaged by grid voltage fluctuations. Placing the relay between the inverter and the grid ensures the inverter is disconnected when grid voltage becomes unstable.

: The device is rated for 60 amps, indicating its capacity to handle a significant amount of current, making it suitable for a wide range of applications. : The "EC" in the model number suggests

The TOMZN TOVPD1‑60‑EC is an adjustable protective relay that monitors voltage and current in a 230 V AC (50/60 Hz) single‑phase circuit. If the measured voltage or current exceeds or falls below the user‑defined safe ranges, the device instantly disconnects the load. Once the electrical values return to normal, the relay automatically reconnects the circuit after a preset delay.

: Users can check the cause of the last trip (e.g., "HU" for high voltage or "LU" for low voltage) by pressing and holding the button for more than 12 seconds. Key Technical Specifications

Proper installation is critical. Miswiring the input and output terminals will permanently damage the device and void its warranty. Step-by-Step Installation Integrate a standard miniature circuit breaker upstream

Turn off high-power appliances or increase the over-current setting if wiring permits.
