Weidmuller 1880390000 Terminal Block Indicator 140-250V

Product Description

The WEIDMULLER 1880390000 is a WSI 4/2 LD series terminal block indicator light designed for use in industrial control panels and electrical enclosures. It operates across a wide voltage range of 140 to 250 volts, accepting both AC and DC input, which makes it adaptable to a variety of control circuit configurations. The unit integrates directly into terminal block assemblies, providing a visual status indication without requiring a separate mounting footprint. Electricians and panel builders install this component during panel assembly or service when LED or lamp-style status indication is needed at the terminal level.

This indicator light is suited for industrial and commercial electrical panel applications where in-line visual signaling is required at the terminal connection point. Its wide AC/DC voltage compatibility allows installation in diverse control circuits, including those found in HVAC control panels, motor control centers, and general automation enclosures. The black housing blends with standard terminal block rail assemblies.

Key Features

• Wide operating voltage range of 140 to 250 volts covers both AC and DC circuits
• Integrated terminal block form factor eliminates need for separate indicator mounting
• Black housing for clean, uniform appearance on DIN rail assemblies
• WSI 4/2 LD design compatible with Weidmuller terminal block system layouts

Compatibility

Designed as an OEM-style component for use within Weidmuller WSI series terminal block assemblies in industrial and commercial electrical panel applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC guidelines for control panel wiring. De-energize the panel and verify voltage is absent at the terminal rail before installing or removing any terminal block components. Ensure the supply voltage falls within the 140 to 250 volt rated range before energizing. Standard terminal block installation tools and a DIN rail are required for proper mounting.
