Engineering record for XB4BVG4: Harmony XB4 red LED pilot light identity and fit

XB4BVG4 identifies a particular Schneider Electric Harmony XB4 red LED pilot light. This page keeps the exact XB4BVG4 designation visible while distinguishing verified product facts from installation decisions. The shared category collage is a reference image and does not claim to depict the exact XB4BVG4 configuration.

Verified technical parameters

Selection decision

Confirm the panel legend, lens colour and lamp supply; a similar head can require a different light block.

For XB4BVG4, record the existing equipment tag, supply, load, mounting and mating accessories. Compare each item with the verified parameters above and the current manufacturer documentation for XB4BVG4. A code with a similar prefix may change the electrical or mechanical specification.

What to inspect before ordering

Start with a photograph of the complete XB4BVG4 label and the installed connections. For XB4BVG4, check the exact suffix, terminal layout, protective device or controller pairing, and the available panel space. Where the application uses a safety function, a qualified engineer must validate the whole function.

The purchase description should retain XB4BVG4 exactly. Include the equipment ID and any separate accessory codes; a shared picture or family name does not prove that the delivered XB4BVG4 includes every part of an assembly.

Field verification after fitting

Isolate the equipment according to site procedure before installing XB4BVG4. Preserve settings, wiring labels and software backups where they apply. For XB4BVG4, verify supply and signal values, operating states and alarms in a safe test condition.

Record the delivered XB4BVG4 on the commissioning sheet. If a proposed replacement differs from XB4BVG4, document the difference and obtain engineering approval before energising the equipment.
