NewTrend · WiFi voltage current and leakage protector
Product overview
The OMPD-63SW is a single-phase DIN-rail WiFi protector with voltage, current, leakage-current and energy readings. It combines adjustable protection with automatic reconnection and remote switching through Tuya Smart or Smart Life. The switching function disconnects L only; the neutral conductor is not switched.
Protection and metering functions
Monitor voltage, current, leakage current and accumulated kWh on the unit or phone. Set over-voltage, under-voltage, over-current and leakage-current thresholds locally or in the app. Remote ON/OFF control and timer functions are provided. This page offers the WiFi OMPD-63SW; the non-WiFi OMPD-63S shown in the family reference is not an option on this page.

Timers and remote switching
Switch the load remotely from the phone, set scheduled operations, use a countdown or repeat a timing loop. The original app illustrations show the supported timing controls and remote monitoring interface.
Voltage protection settings
The written specification gives under-voltage adjustment from 80 to 210 V with default 170 V, and over-voltage adjustment from 120 to 300 V with default 270 V. The original parameter image and local-menu illustration contain different voltage ranges; use the actual supplied unit menu. Recovery and action parameters are shown in the complete menu diagrams later on this page.
Current protection and reconnection
The written over-current range is 1–63 A, with stated default 40 A. Reconnection delay is 1–500 s, default 30 s. The written action-time range is 1–30 s, default 1 s. Voltage/current/power calibration is adjustable from −20% to +20%.
Leakage-current protection
The original parameter reference gives a leakage-current setting of 10–99 mA. The setting-menu reference also shows an OFF choice, recovery delay and a count limit for repeated leakage faults. The local test key is identified in the front-panel diagram.
App settings
The app provides soft reset, threshold settings, alarm settings and switching controls. The original screenshots show voltage, leakage and current configuration pages.
Alarm and tripping controls
The source app illustrations include an over-current alarm, a threshold setting and a separate breaker-tripping control. Check the selected alarm/tripping settings for the intended circuit.
Energy and voltage history
Review historical electrical data in the app. The examples below show the energy statistics and voltage curve interfaces.
Current and power history
Additional app plots show current and active-power trends for reviewing connected-load operation.
Real-time display
The front display presents voltage and leakage readings above the current and energy display areas. Separate indicators identify voltage, current, leakage, WiFi and energy pulses.
Wiring
Connect the L and N supply to the upper IN terminals and the load to the lower OUT terminals, following the unit markings. The original diagram shows the conductor positions and wiring direction. Only L is switched by the protector.
Front-panel controls
The annotated panel identifies the manual ON/OFF key, SET/menu key, adjustment keys, WiFi function and test function. Refer to the key labels on the actual supplied unit.
Local programming menu: voltage and delays
The original menu diagram includes display brightness, display interval, power-on delay, over-voltage threshold/recovery/delays and under-voltage threshold/recovery/delays. Its voltage and delay ranges differ from some written values, so the complete original diagram is retained as a version reference.
Local programming menu: current, leakage and calibration
The continuation covers current protection and recovery, repeated-fault limits, leakage protection and recovery, voltage/current/power calibration, low-credit energy warning and saving/exiting the menu. Follow the settings available on the actual unit.
Original parameter reference
The illustrated table states over-voltage adjustment 110–300 V, under-voltage adjustment 85–220 V, leakage adjustment 10–99 mA and reconnection 1–500 s. These differ from portions of the written and menu references; confirm the supplied version before programming.
Dimensions
The dedicated drawing shows 95 mm overall height, 38 mm width and 69 mm depth, with a 50 mm side reference. The separate generic parameter illustration states 84 × 36 × 65 mm. Both original references are retained; use actual supplied housing dimensions for cabinet layout.
