ABB MLBL Series LED Block, 230V Voltage, White Illumination - 1SFA611621R2075 MLBL-07BW

This LED Block provides a Compact Visual indicator for control panels and equipment in automation and industrial electrical systems. Designed for panel-mount signalling duties, it offers white illumination powered from standard 230V AC supplies and integrates with screw-terminal wiring for straightforward installation.

Features and Benefits:

• Operates from 230V AC for compatibility with mains control circuits
• Screw Terminal connection simplifies secure electrical termination
• White LED illumination for clear status indication
• Rated to function between -25 °C and 70 °C for wide ambient ranges
• Complies with multiple international standards for regulatory acceptance
• Compact 10mm width aids tight-panel and modular assemblies

Applications

• Suitable for signalling status on control panels in manufacturing plants
• Ideal for use in switchgear and distribution enclosures
• Used for indication on test rigs and diagnostic stations
• Can be used for retrofit upgrades in electrical cabinets
• Used with Terminal blocks and relay sockets in automation racks

What is the recommended wiring approach to ensure reliable connections?

Use appropriately rated conductors and tighten the screw terminals to the torque specified by your installation standards to prevent loosening under vibration.

How does the device perform in elevated-temperature installations?

The indicator maintains specified operation throughout its -25 °C to 70 °C range

position it away from heat sources that exceed the stated maximum to preserve LED lifespan.

What approvals should be checked for international projects?

Verify the product’s conformity marks against project requirements since it carries multiple recognised certifications relevant to cross‑border installations.

How does the unit integrate into Compact panel designs?

Its narrow 10mm profile permits dense placement in modular assemblies, enabling more indicators per panel while conserving front‑panel real estate.
