For safety and performance, the device must be installed on a standard within a distribution board.
Connect the incoming Phase (L) and Neutral (N) to the terminals marked L-IN and N-IN . Output: Connect the load circuit wires to L-OUT and N-OUT .
On a summer day, the grid sags to 160V. Your refrigerator compressor tries to run but overheats and dies. and waits for the grid to recover. Your fridge survives.
: Press the first button to manually turn the load ON or OFF. When OFF, the lower display will show "oFF". tomzn tovpd160ec manual better
Why it matters: Prevents circuit overloads that can melt wires or start fires. Unlike a traditional breaker, you can customize the current limit.
High voltage kills. If you are not a licensed electrician, do not open your distribution panel. This guide is for qualified professionals.
: Press and hold the Set button for roughly 3 seconds until the display screen begins blinking. For safety and performance, the device must be
Press to enter the settings menu, cycles through parameter codes, and saves changes.
Press M briefly to move to the next parameter code (e.g., A1, A2, A3).
TOMZN TOVPD1-60-EC is a multifunctional protection relay designed for single-phase electrical systems, offering integrated over-voltage, under-voltage, and over-current safeguards. Its primary advantage over standard, non-adjustable protectors is its deep level of customization, allowing users to fine-tune thresholds to suit specific local power conditions. Core Technical Capabilities The device is rated for at 50/60Hz and can handle loads up to On a summer day, the grid sags to 160V
The wiring terminals on the TOMZN TOVPD160EC are usually clearly labeled, but here is the standard logic:
The search results popped up. Most were the same useless PDFs. But then, halfway down the page, he saw a link to a niche tech repository titled:
| Step | Action | | :--- | :--- | | 1 | Identify a inside your electrical distribution board. Ensure the main power is completely turned off . | | 2 | Hook the top notch of the TOMZN device onto the top edge of the DIN rail. | | 3 | Press downward firmly on the bottom of the device until the spring‑loaded clip clicks into place. | | 4 | Give the device a gentle tug to confirm it is securely mounted. |
| Terminal | Label | Connection | | :--- | :--- | :--- | | Left Top | L-In | Live from Grid/Main Breaker | | Right Top | N-In | Neutral from Grid | | Left Bottom | L-Out | Live to House Load | | Right Bottom | N-Out | Neutral to House Load |
Why it matters: Low voltage (brownouts) can cause motors to overheat and refrigerators or air conditioners to fail. The device stops power to prevent damage.
