Why Choose the ABB MLBL-05G Lamp Block?
The ABB MLBL-05G is a modular green LED lamp block designed for illuminated operators within ABB's 22 mm modular pilot device range. Supplied under ABB order code 1SFA611621R1052, it provides an integrated light source for compatible pushbuttons, selector switches and other illuminated industrial control devices.
The MLBL-05G operates from a 110–130 V DC supply and incorporates an efficient green LED. The LED has a nominal current of approximately 10 mA, a wavelength of 520 nm and luminance of 1500 mcd, providing a bright and clearly identifiable green indication through a compatible ABB illuminated operator.
Designed for front fastening, the MLBL-05G uses screw connections for secure industrial wiring and incorporates both the LED light source and an integrated diode. Its compact 44 × 10 × 35 mm construction and IP20 terminal protection make it well suited to machinery, automation equipment and industrial control-panel assemblies.

Green LED Indication for ABB Modular Pilot Devices
LED lamp blocks provide the internal illumination behind compatible pilot device operators, allowing operating conditions and machine states to be communicated visually. Green indication is commonly applied to running, ready, normal or satisfactory conditions according to the signalling conventions selected for the particular machine or installation.
The ABB MLBL-05G combines a 110–130 V DC green LED with ABB's modular front-fastening architecture. It can be integrated with compatible illuminated pushbuttons, selector switches and other ABB modular operators, providing a compact illumination solution for machinery and industrial automation panels.
Typical Applications
- Illuminated industrial pushbuttons.
- Machine running and ready indication.
- Automation and process control panels.
- Production and manufacturing equipment.
- Operator stations and control consoles.
- Conveyor and material handling controls.
- OEM machinery and electrical control assemblies.
