Description
The ABB MLBL-04R LED Block (MLBL-04R) is a front-mounted, illuminated LED block engineered for reliable signal indication in industrial control panels. As part of ABB’s Modular Plastic MLBL Series, this LED block offers market-leading electrical ratings, exceptional mechanical durability, and total operational reliability across demanding applications.
Featuring a bright red LED operating at 110 to 130 VAC with screw terminals, the MLBL-04R includes integrated anti-glowing circuitry designed to cut leakage currents and prevent ghost illumination. Built with an impressive service life of up to 50,000 hours, its innovative modular design snaps directly onto ABB modular holders for rapid, tool-free installation behind pilot lights and pushbuttons.
Key Features
- Red LED Illumination: Features a high-visibility red LED operating at 110 to 130 VAC for clear, reliable status and pilot light indication.
- Anti-Glowing Functionality: Built-in circuitry eliminates leakage currents to prevent faint glowing when the circuit is inactive.
- 50,000-Hour Service Life: Engineered for long-term reliability with an operational service life rated at 50,000 hours at 25°C.
- Modular Front Mounting: Snaps easily onto ABB modular operator holders with secure screw terminal connections for fast wiring.
