Electrical wall socket Legrand SUNO double 2x2P+Z white 16A 250V with screw terminals (model 721191)

Legrand SUNO double wall socket delivers two grounded 2P+Z outlets in a single white module rated for 16 A and 250 V. The unit is designed for standard domestic and light-commercial electrical circuits and uses screw terminals to secure conductors, enabling straightforward installation and reliable electrical contact. Its neutral white finish and compact double-module format fit common mounting frames and faceplates for typical wall outlet installations.

Advantages

The socket combines two grounded outlets in one device to save wall space while providing independent receptacles. Screw terminal connections allow solid mechanical clamping of live, neutral and earth conductors, reducing the chance of loose connections over time. Rated for 16 A at 250 V, it supports typical household appliances and equipment. The white finish and standard dimensions ensure compatibility with most faceplates and installation boxes.

Suitable for

• General household power outlets for kitchen, living room, bedroom and home office
• Light commercial and service premises where two grounded receptacles are needed in one location
• Outlet replacement projects in standard single-gang or double-module mounting frames
• Electrical installations requiring screw-terminal connections for secure wiring

Key specifications

• Configuration: double 2P+Z (two grounded outlets)
• Rated current: 16 A
• Rated voltage: 250 V AC
• Terminal type: screw terminals for live, neutral and earth conductors
• Color and finish: white, smooth faceplate
• Compatibility: standard mounting frames and faceplates for double-module sockets

How to use

Before installation, disconnect power at the distribution board and verify the circuit is de-energized. Remove the existing faceplate and mounting module if replacing an outlet. Connect incoming live (L), neutral (N) and protective earth (PE) conductors to the corresponding screw terminals, ensuring conductors are stripped to the recommended length and firmly clamped. Secure the device into the mounting box with appropriate screws and attach the faceplate. Restore power and test each outlet with a suitable tester or appliance to confirm correct wiring and earthing.

Usage recommendations

Use the socket for standard appliances and equipment within the rated 16 A/250 V limits. For high-current devices or specialized circuits consult local electrical regulations and consider dedicated circuits or industrial-grade outlets. Periodically check terminal tightness after installation and have all electrical work performed or inspected by a qualified electrician to ensure safety and compliance.
