DIN-kiskorele WLAN QOLTEC 50881 — verkkovaihtorele 63A sähköasennuksiin

QOLTEC 50881 is a DIN-rail mounted WiFi relay developed for switching mains circuits up to 63A. The device is intended for integration into standard distribution boards and provides remote on/off control of electrical loads through a WiFi connection. Designed for use in residential and light commercial electrical installations, it enables remote switching of lighting, heating devices and pumps, while maintaining a compact footprint suitable for DIN-rail mounting.

Advantages

This mains switching relay supports switching of high-current loads up to 63A while occupying a single module position on a standard DIN rail, simplifying retrofit and new-install wiring. Built-in WiFi connectivity allows remote control and scheduling without additional wiring, and compatibility with common home automation scenarios reduces the need for separate control relays. The relay’s form factor and mounting method are suitable for placement inside distribution and control cabinets, making it easy to integrate into existing electrical panels.

Suitable for

• Remote control of lighting circuits in residential and commercial buildings
• Switching of electric heating systems and boiler control
• Control of water pumps and circulation systems
• Integration into home automation setups for scheduled or remote switching

Key specifications

• Mounting: DIN-rail compatible
• Rated switching current: 63 A (mains)
• Control interface: WiFi (wireless remote control and scheduling)
• Application: mains switching for lighting, heating, pumps and general loads
• Installation location: distribution board / control cabinet

How to use

Install the QOLTEC 50881 on a standard DIN-rail inside a distribution board, connect the mains input and switched output according to local electrical codes, and secure protective covers as required. After power connection, configure WiFi settings and control options using the manufacturer’s setup procedure to connect the relay to a local network and any supported control apps or automation systems. Use the app or integrated control interface to switch the relay, set timers or create automation rules as needed for the specific installation.

Recommendations

Ensure installation and wiring are performed by a qualified electrician and comply with national electrical regulations. Verify the connected load does not exceed the 63A rated switching current and use appropriate protective devices, such as circuit breakers and residual-current devices, in the distribution board. Keep the relay and its wiring enclosed within the distribution cabinet to maintain safe operation and environmental protection.
