Why Choose the ABB MLBL-04BW Lamp Block?
The ABB MLBL-04BW is a compact and reliable white LED lamp block designed for visual indication in industrial control, signalling and automation applications. Supplied under ABB order code 1SFA611621R2045, it forms part of the ABB MLBL modular pilot device range and provides integrated LED illumination for compatible operator and signalling devices.
The MLBL-04BW incorporates an integrated white LED light source, providing clear illumination without requiring a separate replaceable lamp. Designed as a rear-mounted LED block, it can be used in compatible ABB MEP plastic enclosures or DIN-rail installations, making it a flexible solution for industrial operator interfaces and control equipment.
With a rated operating voltage of 110–130 V AC and a rated current of 15 mA, the MLBL-04BW is designed for industrial AC control circuits. Its white LED provides a neutral, highly visible indication suitable for machine status, process signalling and illuminated control functions.
