TOMZN TOMPD-63SW 63A Tuya WiFi Smart Relay Switch

The TOMZN TOMPD-63SW is a high-capacity 63A Tuya WiFi Smart Relay Switch with voltage, overcurrent and leakage current protection, designed for smart electrical control, power monitoring and protection against abnormal voltage conditions.

Through the Tuya Smart / Smart Life App, you can remotely switch the connected electrical circuit ON or OFF while monitoring real-time electrical parameters such as voltage, current and power consumption.

A particularly useful feature of the latest version is Last State Memory. After a power failure and subsequent power restoration, the device can restore the previous ON/OFF state instead of automatically switching the output ON.

This makes it especially practical for electrical systems in Bangladesh where unexpected power interruptions and restoration (also known as loadshedding) are common.

Important: The TOMPD-63SW is a smart relay switch and voltage/leakage current protector, not a circuit breaker. It should not be relied upon for short-circuit protection. A suitable circuit breaker/MCB should be installed separately as required by the electrical system.

Smart WiFi Control Through Tuya App

Connect the TOMPD-63SW to your 2.4GHz WiFi network and control it through the Tuya Smart / Smart Life App.

From your smartphone, you can:

• Turn the output ON/OFF
• Monitor voltage
• Monitor current
• Monitor power consumption
• View electrical parameters remotely
• Configure protection thresholds
• Configure timing and delay settings

This allows convenient monitoring and control without needing to physically access the electrical panel.

Last State Memory After Power Failure

A Particularly Useful Feature for Bangladesh

The latest version of the TOMPD-63SW introduces Last State Memory.

Previously, after a power failure and restoration, the device would turn its output ON even if the user had switched it OFF before the outage.

The updated version can remember the last output state.

For example:

Before power failure:
Output = OFF

Power fails → Power restored:
Output = OFF

Similarly:

Before power failure:
Output = ON

Power fails → Power restored:
Output = ON

This can be particularly valuable for homes, offices, equipment and electrical systems where an unwanted automatic restart could be inconvenient.

Adjustable Over-Voltage & Under-Voltage Protection

The TOMPD-63SW can monitor the incoming voltage and disconnect the output when the voltage goes outside the configured protection range.

Under-Voltage Protection

Adjustable under-voltage threshold:

85V–220V

Over-Voltage Protection

Adjustable over-voltage threshold:

110V–300V

This helps protect connected equipment from abnormal supply voltage conditions.

Leakage Current Protection

The device also monitors leakage current and can disconnect the output when the configured leakage threshold is exceeded.

This makes the TOMPD-63SW useful as an additional protective and monitoring device in electrical installations where leakage-current monitoring is required.

Important: Leakage-current protection should not be confused with short-circuit protection. The TOMPD-63SW is not a replacement for an MCB or suitable circuit breaker.

Real-Time Electrical Monitoring

One of the most useful smart features is its ability to monitor electrical parameters through the Tuya App.

You can view:

• Voltage (V)
• Current (A)
• Power (W)
• Energy Consumption (kWh)
• Leakage Current

This gives you a convenient way to monitor the electrical load connected through the device.

Remote ON/OFF Smart Relay Control

The TOMPD-63SW is not simply a monitoring device—it also functions as a 63A smart relay switch.

Through the Tuya App, you can remotely:

Turn ON → Turn OFF

This can be useful for remotely controlling high-power electrical circuits, equipment and selected household or commercial loads within the device’s electrical specifications.

Timer & Reconnection Delay Settings

The TOMPD-63SW provides configurable timing functions for automated electrical control.

The reconnection delay can be configured from approximately:

1–500 seconds

with a default setting of approximately 30 seconds.

This delay can help prevent immediate reconnection following certain protection events.

DIN Rail Installation

The TOMPD-63SW is designed for DIN rail mounting, making it suitable for installation inside electrical distribution boards and control panels.

Its DIN-rail form factor makes it convenient for:

• Residential electrical panels
• Smart home electrical systems
• Office electrical panels
• Commercial installations
• Equipment control panels
• Industrial electrical applications

Professional electrical installation is recommended.

Important: This Is NOT a Circuit Breaker

Do Not Use It as Short-Circuit Protection

The TOMPD-63SW should not be described or treated as a conventional circuit breaker.

It is a:

Smart Relay Switch + Voltage Protector + Overcurrent Protector + Leakage Current Protector + Electrical Monitoring Device

It does not provide conventional short-circuit protection.

In the event of a short circuit, the device itself may be damaged. Therefore, an appropriate MCB/circuit breaker or other required short-circuit protection device must be installed separately according to the electrical installation design.

This distinction is important when selecting and installing the product.

Suitable Applications

The TOMPD-63SW can be used for smart electrical control and monitoring in:

• Smart Homes
• Apartments
• Offices
• Shops
• Commercial Buildings
• Electrical Distribution Panels
• Equipment Control Panels
• Industrial Applications
• High-Load Electrical Circuits
• Smart Energy Monitoring Systems
