Switching actuator Meross MSS810

The Meross MSS810 switching actuator is a compact smart home module designed to control electrical loads up to 400 W. It accepts an input voltage range of 100–250 V at 50/60 Hz and integrates into home automation setups to switch lighting, small appliances or other compatible circuits. The unit’s small footprint (50 mm width, 46 mm depth, 19 mm height) allows installation in distribution boxes, behind switches or inside fixtures where space is limited.

Advantages

The device provides reliable on/off switching for loads up to 400 W while supporting modern wireless security with WPA3-PSK for encrypted connections. Its wide input voltage range and dual-frequency compatibility make it suitable for various regional power systems. The compact dimensions simplify installation and mounting in confined electrical enclosures. The actuator’s design focuses on functional interoperability with smart home controllers and standard electrical installations.

Suitable for

• Switching LED and incandescent lighting circuits within the specified power limit
• Controlling small household appliances and fans up to 400 W
• Integration into smart home scenes and automation routines
• Installation in distribution boards, wall boxes or fixture housings with limited space

Key specifications

• Maximum switching capacity: 400 W
• Input voltage: 100–250 V
• Frequency support: 50/60 Hz
• Wireless security: WPA3-PSK supported
• Dimensions (W × D × H): 50 mm × 46 mm × 19 mm

How to use

Install the switching actuator in accordance with local electrical codes, placing it inside a distribution box, behind existing switches or within compatible fixture housings. Connect the line and load conductors to the designated terminals and ensure proper grounding where required. After wiring, power the circuit and follow the Meross app or compatible smart home controller instructions to add the device to the network and configure switching behavior, schedules or scenes. Verify correct operation by testing on/off control and monitoring load temperature and performance during initial use.

Usage recommendations

Use the Meross MSS810 only within its rated capacity (up to 400 W) and suggested voltage range to avoid overload. Ensure secure network configuration by enabling WPA3-PSK where available and keep device firmware up to date. For inductive or high inrush loads, verify compatibility or use an appropriately rated actuator. When installing in confined enclosures, allow for ventilation and avoid placing the module in locations with excessive heat or moisture.
