I couldn’t find an official manual for the Tomzn TOVPD1-60-EC in my current knowledge base or browsing results. This appears to be a specific DC circuit breaker / protector (likely from Tomzn, a brand that makes solar/DC components), but the model number may be partially incorrect or less common.
Here’s what I recommend to find the manual:
Check your purchase platform – If you bought it from Amazon, AliExpress, or eBay, the seller often uploads PDF manuals in the product listing or “Product Information” section.
Search directly on Google (try these search strings):
"Tomzn TOVPD1-60-EC" manual filetype:pdfTomzn TOVPD1-60-EC user guideTomzn DC circuit breaker TOVPD1 manualCheck Tomzn’s official channels – Tomzn products are often sold through multiple resellers; they don’t always have a centralized website. However, you can look for the official Tomzn store on AliExpress or Amazon — they sometimes list manuals in the “Technical Specification” section.
Use a generic model – The TOVPD1 series likely shares a common manual. Search for “Tomzn TOVPD1 manual” (without -60-EC). The 60 may refer to 60A rating, and EC might be a variant.
Contact the seller – If the manual isn’t online, ask the seller directly — many provide it upon request.

TOMZN TOVPD1-60-EC Manual: Installation, Settings, and Troubleshooting TOMZN TOVPD1-60-EC is a dual-display DIN rail protector
The TOMZN TOVPD1-60-EC is a multifunctional protective device designed to safeguard household appliances and industrial equipment from voltage fluctuations and overcurrent issues. This guide provides a comprehensive overview of its features, installation process, and programming settings. Technical Specifications
Before installation, ensure your electrical system matches these core specs: Rated Voltage: 230V AC (50/60Hz) Current Range: 1A to 60A (Adjustable) Over-voltage Protection Range: 230V – 300V Under-voltage Protection Range: 140V – 210V Recovery Delay Time: 1s – 500s Installation Guide
The TOVPD1-60-EC is designed for 35mm DIN rail mounting, typically installed inside a consumer unit or distribution board.
Safety First: Turn off the main power supply before beginning. Wiring:
Input: Connect the live wire to the L (IN) terminal and the neutral wire to the N (IN) terminal at the top.
Output: Connect your load to the L (OUT) and N (OUT) terminals at the bottom.
Tightening: Ensure all terminal screws are tightened securely to prevent arcing or overheating. Programming and Settings
To enter the setup mode, press and hold the "SET" button for 3 seconds. Use the Up and Down arrows to adjust values. Default Value A1 Over-voltage Protection Value 230V–300V A2 Over-voltage Recovery Value 225V–295V A3 Over-voltage Protection Action Time 0.1s–30s A4 Under-voltage Protection Value 140V–210V A5 Under-voltage Recovery Value 145V–215V A6 Under-voltage Protection Action Time 0.1s–30s A7 Over-current Protection Value A8 Over-current Protection Action Time 0.1s–30s A9 Recovery Delay Time (Power-on time)
Note: The "Recovery Value" is the voltage level at which the device restores power after a fault has been cleared. Display Indicators
Digital Display: Shows real-time voltage (V) and current (A).
Green Light: Indicates the device is in a normal working state.
Red Light: Indicates a fault (Over-voltage, Under-voltage, or Over-current). Troubleshooting Common Issues
Device won't turn on: Check if the input wiring is reversed or if the main breaker is tripped.
Frequent Tripping: 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.
No Output Power: Check the recovery delay timer (A9). The device will wait for the set duration before restoring power after a trip or initial startup. Maintenance Periodically check terminal tightness.
Keep the device clean and free from dust to prevent overheating.
Ensure the ambient temperature remains within -5°C to +40°C for optimal performance.

Title: Understanding the TOMZN TOVPD1-60-EC: A Comprehensive Guide to the 60A DC Mini Circuit Breaker
Before diving into the manual’s operational steps, it’s essential to understand what this device is. The model number decodes as follows:
Unlike a standard miniature circuit breaker (MCB) that only protects against short circuits and overloads, the TOVPD1-60-EC protects your entire home or a specific heavy-load circuit from dangerous voltage fluctuations.
If you are reading this article because your device is beeping, flashing, or tripping, refer to this troubleshooting table extracted from standard TOMZN manuals.
| Symptom | Error Code/Cause | Solution | | :--- | :--- | :--- | | Screen is completely dead | No power on Neutral input terminal. | Check wiring: Top neutral terminal must be connected to mains neutral. | | Trips immediately after turning on | Overload > 60A or Short circuit. | Unplug devices and try again. If trips with nothing connected, internal MCB is faulty. | | Displays "U-Err" | Under-Voltage fault. | Voltage dropped below P2 setting. Wait for utility restoration or increase P2 value (if safe). | | Displays "O-Err" | Over-Voltage fault. | Voltage rose above P1 setting. Danger! Check transformer taps or utility supply. | | Buzzer keeps beeping | Voltage approaching dangerous limits. | Manual override: Press button once to silence buzzer. Investigate grid voltage. | | Trips, but doesn't auto-reclose | Reconnect delay (P3) still counting down. | Wait. Default is 30 seconds. If longer, check manual settings. | | App says "Offline" but breaker works | WiFi module lost router connection. | Power cycle the breaker (turn off mains, wait 1 min, turn on). Re-pair. |
| Problem | Possible cause | Solution | |---------|----------------|----------| | Load always off, red LED solid | Voltage out of range (check with meter) | Wait for grid recovery or adjust setpoints | | Green LED off, no output | No input power / internal fuse blown | Check upstream breaker, replace device if dead | | Rapid on/off cycling | Loose neutral connection | Tighten N terminals at unit and mains | | Auto-reset never happens | Unit in permanent fault mode | Cycle mains power; if persists, replace unit | | Unit hot (>50°C) | Overload >60A or poor ventilation | Reduce load, increase air gap around DIN rail |
| Parameter | Value | |-----------|-------| | Model | TOVPD1-60-EC | | Rated Current | 60A (resistive load recommended derating) | | Rated Voltage | 230V AC ~ 50/60Hz | | Over-voltage trip point | 275V ± 5V (adjustable on some variants) | | Under-voltage trip point | 170V ± 5V (adjustable on some variants) | | Auto-reconnect delay | 30–60 seconds after voltage normalizes | | Trip reaction time | ≤ 0.1s (over/under) | | Reset method | Automatic (EC) | | Protection class | IP20 | | Mounting | 35mm DIN rail | | Terminal capacity | ≤ 16mm² rigid wire | | Power consumption | < 1W (idle) |
