ABB 1SFA611621R1075 MLBL-07W front-mounted white LED illumination block for compatible modular plastic pilot devices operating from a 230 V AC supply.
£16.07
The ABB 1SFA611621R1075, product designation MLBL-07W, is a compact and reliable white LED illumination block designed for ABB modular plastic pilot devices. It provides clear visual indication within machinery control panels, operator stations and industrial automation systems.
This front-mounted LED block combines the light source and supporting electronics within a single modular component. Its integrated LED removes the need for a separate replaceable lamp, helping simplify installation and reduce routine maintenance requirements.
Designed for operation from a 230 V AC supply at 50 / 60 Hz, the MLBL-07W produces white illumination for compatible ABB pushbuttons, pilot lights and selector-switch operators. Screw-clamp terminals provide secure connections for solid or flexible conductors from 0.75–2.5 mm².
LED blocks illuminate compatible pushbutton, pilot-light and selector-switch operators, helping personnel identify equipment conditions and active control functions. White illumination provides a clear, neutral indication suitable for a wide range of machinery and process-control applications.
The modular design allows the MLBL-07W to be installed behind a compatible ABB operator using the appropriate holder. This provides panel builders with a flexible method of creating illuminated control devices while maintaining a consistent operator interface.
