Tomzn Tovpd160ec Manual Better May 2026

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

. It features a dual LED display that provides real-time monitoring of both voltage and current, ensuring that homeowners or industrial operators can diagnose power stability at a glance. Key adjustable parameters include: Over-voltage (A2): Set between 230V and 300V (Default: 270V). Under-voltage (A6): Set between 140V and 210V (Default: 170V). Over-current: Adjustable from 1A to 63A to prevent circuit overloads. Recovery Delay (A4):

Users can define how long the device waits before reconnecting power after a fault, typically ranging from 1 to 500 seconds. Programming and Operation According to the TOVPD1-60-EC configuration guidelines

, the device uses a simple four-button interface for manual control and parameter adjustments: Setting Mode: Pressing the tomzn tovpd160ec manual better

button enters the configuration menu where parameters (A1 through A14) can be adjusted using the Up and Down keys. Manual Override:

The power button allows for manual disconnection of the load, displaying "oFF" when inactive. Fault Inquiry: Holding the

button for more than 12 seconds displays the reason for the last trip (e.g., high or low voltage). Factory Reset: Holding the and usage guidelines.

Note: No official Tomzn manual exists under that exact model code in public databases as of 2026. This guide assumes TOVPD160EC is a 160A two-pole or four-pole residual current circuit breaker with over/under voltage protection (common in Tomzn’s “TOVPD” series). Adjust based on the actual device label.

2. The timer switches on at the wrong time.

You likely have the Day of the Week set incorrectly. Re-enter programming mode and check if the schedule is set to "Every Day" or specific days. offering integrated over-voltage
