Dimmer switch LIREGUS DIMMER 400W without frame, model ISR-002-01E/J, 400W load control

The LIREGUS DIMMER 400W without frame (model ISR-002-01E/J) is a wall-mounted lighting control module intended for installation behind a separate decorative frame or faceplate. Designed to manage a total load up to 400 watts, this dimmer provides adjustable brightness control for compatible incandescent, halogen and dimmable LED lamps. It fits standard electrical backboxes and integrates into residential and light-commercial lighting circuits where a frame is supplied separately.

Advantages

This dimmer enables smooth manual adjustment of light intensity to create the desired ambience or to save energy by reducing lamp output. Its 400W capacity supports multiple fixtures on a single circuit when lamp types and combined load remain within rated limits. The frameless design simplifies compatibility with a variety of decorative faceplates and allows flexible installation choices. The device provides straightforward wiring and operation suitable for common retrofit and new-build scenarios.

Suitable for

• Controlling incandescent and halogen lamp circuits up to a combined 400W.
• Controlling dimmable LED fixtures when those LEDs are explicitly rated as compatible with leading-edge (triac) dimmers.
• Residential rooms such as living rooms, bedrooms and dining areas where a separate decorative frame will be fitted.
• Light-commercial spaces with compatible loads and conventional wall-box mounting.

When it may not be suitable

This dimmer is not appropriate for loads that exceed the 400W total rating. It may also be unsuitable for some low-wattage or non-dimmable LED lamps and electronic drivers that require specific trailing-edge dimmers or proprietary control protocols. In multi-way circuits or systems requiring electronic switching, confirm compatibility with the existing wiring and control scheme before installation.

Key specifications

• Maximum controllable load: 400 watts (total circuit)
• Mounting: wall-mounted module designed for installation behind a separate faceplate
• Compatible lamp types: incandescent, halogen, dimmable LED (confirm LED compatibility)
• Control type: manual rotary or push-dim (depends on front control fitted with faceplate)
• Mounting box compatibility: standard electrical backbox depth as required for wall modules

How to use

Install the dimmer module into a standard wall backbox and secure it before attaching the decorative frame or faceplate. Connect live, load and neutral/earth conductors according to local wiring regulations and the product wiring diagram supplied with the unit; ensure power is isolated during installation. Once mounted and powered, adjust brightness using the front control provided by the chosen faceplate accessory. Test different lamp types and settings to confirm smooth dimming and absence of flicker.

What to consider before purchase

• Verify the combined wattage of lamps on the circuit does not exceed 400W.
• Check that the lamps or LED drivers are listed as compatible with leading-edge (triac) dimmers.
• Confirm the chosen decorative frame or faceplate is compatible with a frameless module of this size and mounting style.
• Ensure your installation location has an appropriate wall backbox and that local electrical codes are followed.

Usage recommendations

For best results use dimmable lamps from reputable manufacturers and test one fixture first when retrofitting LEDs. If flicker or instability is observed, consult the lamp specifications or consider a dimmer model with a different control method. Always switch off mains power before installation and consult a qualified electrician for multi-way circuits or uncertain wiring situations.
