ZAMEL four-channel 230V radio mains switch RWS-311C/Z — 4 outputs 16A, range 350m, IP56

The ZAMEL four-channel 230V radio mains switch RWS-311C/Z is a compact unit designed to switch four independent 230V AC circuits. Each channel provides a relay output rated for 16A, allowing control of lighting, motor loads, pumps and other household or light-commercial devices. The module supports wireless control up to 350 m in open area and features IP56 protection, making it suitable for installations in exposed or dusty environments where splash resistance and dust protection are required.

Advantages

The device combines multi-channel switching with high current capacity per channel, enabling simultaneous control of several circuits from a single unit. Wireless operation simplifies installation and eliminates the need for running additional control wiring. IP56 ingress protection increases installation flexibility, permitting use in outdoor housings, technical rooms and other locations subject to dust or occasional water spray. The compact design facilitates mounting inside junction boxes or control cabinets.

Suitable for

• Remote switching of outdoor and indoor lighting circuits
• Control of motorized equipment such as gate or roller shutter drives
• Operation of pumps and circulation systems
• Centralized switching in small commercial installations

Key specifications

• Supply voltage: 230 V AC
• Number of independent outputs: 4
• Contact rating per output: 16 A (AC)
• Wireless control range: up to 350 m (open area)
• Enclosure protection rating: IP56
• Suitable for mounting in junction boxes or control cabinets

How to use

Install the switch in accordance with local electrical regulations, ensuring power is disconnected before wiring. Connect the incoming 230 V supply and the four load conductors to the designated terminals, observing correct phase and neutral connections where applicable. Pair compatible radio transmitters or remote controls following the manufacturer's pairing procedure to enable wireless control of each channel. After wiring and pairing, restore power and test each output with the intended loads to confirm correct operation.

Usage recommendations

For reliable long-term performance, mount the unit in a ventilated but protected enclosure if installation is in an area exposed to direct water jets or heavy dust. Use conductors and protective devices sized for 16 A loads per channel and follow local wiring codes; include appropriate overcurrent protection and motor protection where required.
