ABB MLBL Series LED Block, 60V Voltage Rating, 10mm Width - 1SFA611621R1035 MLBL-03W

This LED Block is a Compact panel indicator designed to provide clear white illumination for control and signalling tasks in industrial electrical and automation installations. It operates from low-voltage AC or DC supplies and mounts as a light Block with a screw connection for straightforward electrical termination.

Features and Benefits:

• Rated for operation at 60V AC/DC for versatile supply compatibility
• White LED illumination for high-contrast Visual signalling
• Screw Terminal design enabling secure conductor clamping
• RoHS-compliant construction reducing hazardous substances risk
• Wide operating range from -25°C to 70°C for harsh environments
• Small footprint with 10mm width for dense panel layouts

Applications

• Suitable for control panels requiring Compact Visual indicators
• Ideal for automation racks monitoring status signals
• Used with Terminal blocks in electrical distribution cabinets
• Can be used for signalling on machinery control stations
• Suitable for retrofitting LED indicators into existing switchgear

What is the electrical compatibility with control circuits?

It accepts both alternating and direct supplies up to 60V, allowing integration with common low-voltage control buses.

How is the device connected to existing wiring?

Termination is via a screw-type Terminal that provides mechanical retention and electrical contact for standard conductor sizes.

What environmental conditions can it tolerate?

It operates across a temperature span from -25°C to 70°C, suitable for ambient conditions encountered in many industrial locations.

Does the unit include the light source or require external lamps?

The light source is integrated

the Block is supplied with a white LED fitted and ready for installation.

What form factor should installers expect for panel integration?

The indicator is a Compact light Block with a narrow 10mm profile intended for use where panel space is limited.
