Harmony XB4 Ø22 yellow pilot light head with standard lens and integrated LED ZB4BV083

Professional signal lamp head Harmony XB4

The Harmony XB4 yellow power signal lamp head Ø22 with a standard lens and integrated LED provides a reliable solution for power status signaling systems in industrial applications. The product, with a mounting diameter of 22.5 mm, features a round yellow lens and a single built-in light indicator.

Construction and technical parameters

The lamp is made of chrome-plated metal, ensuring high mechanical resistance and an aesthetic appearance. The lens has a diameter of 29 mm for both the width and height of the mounting hole. The device operates in a wide temperature range from -40°C to +70°C, enabling its use in harsh environmental conditions.

The IP66 protection rating guarantees full dust tightness and resistance to water jets from any direction. Additionally, the product meets the requirements of IP67, IP69, and IP69K protection classes, as well as NEMA 13 and NEMA 4X standards. Mechanical resistance is confirmed by the IK06 class according to the IEC 50102 standard.

Applications and compatibility

The solution has been specifically designed for the Schneider Electric Harmony XB4 series and is compatible with universal LED modules. The head is used as a power status signaling element in electrical switchboards, control cabinets, and operator panels across various industrial sectors.

The product can be mounted on both finished hole panels and printed circuit boards (PCB). The required board thickness is a minimum of 1.6 mm, and the mounting hole diameter is 22.4 mm ± 0.1. The mounting system allows for precise positioning with a tolerance of ±2°30'.

Advantages of use and certifications

The integrated LED eliminates the need for external light sources, simplifying installation and reducing the risk of failure. The yellow lens color ensures excellent signal visibility even in difficult lighting conditions.

The device has undergone rigorous endurance testing - it withstands 5 million switching cycles without loss of parameters. Vibration resistance is 5 gn within a frequency range of 2…500 Hz, and shock resistance is 30 gn (18 ms) and 50 gn (11 ms) under sinusoidal acceleration.

The product meets the requirements of international standards UL 508, EN/IEC 60947 series, and CSA C22.2 No 14 standards. It holds RoHS and REACh certifications, confirming environmentally responsible production. The net weight is only 26 grams, facilitating installation without overloading the panel structure.
