140V – 210V (Default: 170V) Over-Current Protection Range: 1A – 63A (Default: 40A) Power Recovery Delay Time: 1s – 500s (Default: 30s) Action Trip Delay Time: 0.1s – 30s (Default: 0.5s) Power Consumption: ≤ 2W Electrical Machinery Life: ≥ 100,000 Cycles Installation: 35mm DIN Rail Wiring and Installation Diagrams

| Symptom | Possible Cause | Remedy | |---------|---------------|--------| | The relay does not close (no output) | Voltage outside the safe range, or power‑on delay active | Check voltage display; wait for delay time to expire | | Frequent tripping on over‑voltage | Supply voltage fluctuating above threshold | Increase the over‑voltage set point or check the mains supply stability | | Frequent tripping on under‑voltage | Supply voltage dropping below threshold | Lower the under‑voltage set point or verify that the supply wiring is adequate | | Relay trips on over‑current immediately after starting a motor | Motor starting current exceeds the over‑current setting | Increase the over‑current threshold or extend the protection action time to ignore short inrush current | | Display shows “none” or a fault code | Last trip was due to a protection event | Press and hold UP for 12 s to view the fault reason | | Settings lost after power off | Possible internal memory failure (rare) | Re‑enter settings; if problem persists, contact TOMZN support |

This comprehensive guide serves as an extended manual and setup guide for operating, wiring, and programming the TOVPD1-60-EC device. Technical Specifications tomzn tovpd1-60-ec manual

: It acts as a safeguard against electrical surges (over-voltage), brownouts (under-voltage), and overloads (over-current). Real-Time Monitoring

The TOMZN TOVPD1-60-EC is a professional-grade DIN-rail device that automatically disconnects a circuit when voltage or current exceeds or falls below safe thresholds, preventing damage to sensitive electronics, motors, and appliances. It is part of the broader TOVPD1 series and features independent adjustable thresholds for over-voltage, under-voltage, and over-current protection. The device integrates a dual-display showing real-time voltage and current, enabling electricians to set precise limits. Models are available for both 230V and 110V systems and can be rated from 40A up to 80A. 140V – 210V (Default: 170V) Over-Current Protection Range:

Data sources:

This usually means your limit settings are too tight. For example, if your local grid fluctuates to 250V often, you may need to increase the A1 setting to 260V. It is part of the broader TOVPD1 series

The duration the current overload must persist before the device executes a trip. Fault Recovery Delay Time 1s – 500s

If you need help configuring specific thresholds for your setup, let me know:

Ensure all terminal screws are tightened securely to prevent arcing or overheating. Programming and Settings

The is a popular, cost-effective digital automatic over-voltage and under-voltage protective device with over-current protection . Designed for DIN-rail mounting, this 63A device is an essential component for safeguarding sensitive home appliances against power fluctuations.
