Telephone socket Schneider Electric EPH4100121 1×RJ11 white

Schneider Electric EPH4100121 is a single-port RJ11 telephone socket in a white finish, designed for mounting into a standard wall box. The unit provides a single RJ11 jack for connecting one analogue telephone handset, fax machine or basic ADSL modem. Its compact form and neutral colour make it suitable for residential rooms, small offices and business premises that require a discreet, fixed connection point for a single landline or basic telephony device.

Advantages

The Schneider Electric telephone socket delivers a reliable, standardized RJ11 interface compatible with most analogue telephones and legacy data devices. The product features a durable plastic faceplate and a simple, low-profile design that blends with common interior finishes. Installation uses standard terminal connections suitable for conventional in-wall wiring, allowing a tidy, fixed connection without external adapters.

Suitable for

• Connecting a single analogue telephone handset in a home or office.
• Providing a wall outlet for a fax machine or basic ADSL modem (single-line use).
• Replacement of an existing single RJ11 wall socket during renovation.
• Small offices or reception areas where only one fixed landline point is required.

When it may not be suitable

This single-port socket is not intended for multi-line telephone systems or installations that require more than one RJ11 outlet at the same location. It does not provide integrated surge protection, broadband filtering, or advanced wiring features; additional inline devices or specific faceplates are required if those functions are needed. For digital or VoIP systems that use Ethernet or different connectors, this analogue RJ11 socket will not be appropriate.

Key specifications

• Connector type: 1 × RJ11 (6P2C/6P4C compatible for single-line use)
• Mounting: flush wall mounting into standard back box
• Colour: white
• Material: durable plastic faceplate
• Intended use: single analogue telephone line / basic data device
• Wiring: screw/terminal connections for in-wall copper wiring

How to use

Turn off the line supply before installation. Mount the faceplate into a standard flush wall box and connect the incoming copper pair to the terminal screws following the line and tip polarity markings. Secure the socket to the box and attach the faceplate. After installation, plug an RJ11 telephone cord into the socket to verify dial tone and functionality. If using with ADSL, install any required filter or splitter inline between the socket and the modem where applicable.

What to consider before purchase

• Confirm that your service uses an analogue single telephone line and compatible RJ11 connector.
• Check wall box depth and mounting compatibility before ordering.
• Determine whether you need surge protection, ADSL filtering, or multiple outlets—this unit provides only a basic single socket.

Usage recommendations

For reliable operation, use standard RJ11 cords and ensure clean, secure terminal connections. When integrating with broadband services, place an ADSL splitter or filter as required by your internet provider to avoid line interference. If you plan multiple devices or want enhanced protection, consider combining this socket with appropriate inline surge or filtering modules.
