Snap the device onto a standard 35mm DIN rail inside your distribution box or consumer unit. Wiring Configuration
UPS systems and battery chargers are often sensitive to both over‑voltage and under‑voltage. The TOVPD1‑60‑EC prevents these devices from operating outside their safe input range.
Terminal connections (typical):
In factories and workshops, the relay can be used to protect motor control circuits, HVAC systems, and automation panels. The over‑current function adds an extra layer of protection against overloads. tomzn tovpd1-60-ec manual

Once voltage or current returns to safe, preset parameters, the internal countdown timer activates. When the countdown reaches zero, the relay automatically closes, restoring power to the circuit. Troubleshooting Guide Potential Cause No input power or wrong wiring.
Automatically restores power once the line voltage and current return to the preset safe range.
Follow these steps to program individual protection thresholds and delay timers. A LED Flashing : Indicates an over-current protection
Connect the hot wire feeding your consumer unit or appliances to the terminal marked OUT L . Connect the load neutral wire to the terminal marked OUT N .
