1SFA611621R1031 ABB MLBL-03R 60 V AC/DC Red LED Lamp Block

Why Choose the ABB MLBL-03R Red LED Lamp Block?

The ABB MLBL-03R is a red LED lamp block designed for compatible ABB Modular illuminated pilot devices used in industrial machinery, control panels and automation systems. Its integrated LED provides a compact and dependable light source for illuminated pushbuttons, selector switches and pilot lights.

Designed for a rated supply of 60 V AC/DC, the MLBL-03R uses a red LED with a rated current of 13 mA. The LED has a wavelength of 620 nm and luminance of approximately 350 mcd, providing clear red visual indication for machine status, alarms and operator-control functions.

The MLBL-03R is designed for front mounting and incorporates the LED directly within the lamp block. Its modular construction allows it to be combined with compatible ABB illuminated operators and pilot-light heads, while the design helps prevent unwanted glowing caused by leakage current. ABB identifies this exact lamp block under order code 1SFA611621R1031.
