The product ZB4BW313 from Schneider Electric is a front element for illuminated pushbuttons from the Harmony XB4 series. It serves as an ergonomic operating element in industrial and building technical installations and is mounted in a hole with a diameter of 22.5 mm. The front element is unlabelled, tactile, and white in colour, with the cap/actuator or lens colour also being white. It features a simple lens for optical signal transmission. The assembly is designed for use with universal LED modules, enabling flexible adaptation to various applications.

Front element

The front element is of standard type and made of chrome-plated metal, ensuring high mechanical stability and corrosion resistance. The shape of the signal unit head is round, supporting intuitive operation. Mounting is done using a vibration-resistant connection screw, ensuring secure fixation in the enclosure. The CAD dimensions are 29 mm width, 29 mm height, and 30 mm depth, facilitating planning in enclosures and control panels.

Applications

Due to its high robustness and protection ratings IP66, IP67, IP69, and IP69K, defined according to IEC 60529, the device is suitable for use in demanding environments, including outdoor areas, where it is protected against dust, water, and high-pressure cleaning. Resistance to high-pressure cleaners is 7000000 Pa at 55 °C and a distance of 0.1 m. The operating temperature ranges from -40 °C to +70 °C, ensuring reliable function even under extreme environmental conditions.

Functions and equipment in detail

The device has a mechanical life of 10,000,000 cycles, meaning long operational life without wear or loss of function. Shock resistance is 30 gn (18 ms) and 50 gn (11 ms) for sine half-wave acceleration, according to IEC 60068-2-27, ensuring suitability for vibrating or shock-loaded environments. Vibration resistance is 5 gn in the frequency range of 2 to 500 Hz, according to IEC 60068-2-6. The overvoltage category is Class I according to IEC 60536, ensuring safe electrical insulation.

Technology explained simply

The protection rating IP66 means the device is dust-tight and protected against water jets from any direction. IP67 additionally protects against temporary submersion, while IP69 and IP69K offer protection against hot steam and high-pressure cleaning, which is relevant for hygiene in food or pharmaceutical facilities. The protection rating IK06 according to IEC 62262 protects against mechanical impacts, such as a 5 kg object dropped from 0.5 m height. Standards IEC 60947-5-4, IEC 60947-1, CSA C22.2 No. 14, UL 508, and others guarantee international usability and safety.

Compatibility and accessories

The front element ZB4BW313 is compatible with universal LED modules and can be combined with various accessories to create a complete device. These include mounting flanges, auxiliary switches, and other components from the Harmony XB4 series. Suitable accessories include, for example, the device carrier ZB4BZ009, the sign holder ZBYLEG201001, or the empty housing XAPD1201. Combining with other components allows individual adaptation to specific requirements.

Mounting and installation

Mounting is done in a hole with a diameter of 22.5 mm. Fixation is achieved using a vibration-resistant connection screw. When installing on insulating supports, earthing of the device is required. The use of accessory ZB5AZ905 is recommended to securely tighten the nut. Compliance with the prescribed mounting and wiring instructions is necessary to ensure safety and functionality.

Advantages in operation

The high mechanical life, extreme temperature resistance, and various protection ratings make the front element ZB4BW313 a reliable component in demanding applications. The modular design enables flexible and cost-efficient adaptation to different requirements. Certifications according to CSA, UL, DNV, and other standards ensure international use. The Green Premium environmental label provides information on material contents and environmental impacts, supporting sustainability goals.

Certifications and standards

The device complies with standards IEC 60947-5-4, IEC 60947-1, CSA C22.2 No. 14, IEC 60947-5-1, JIS C8201-5-1, IEC 60947-5-5, UL 508, JIS C8201-1. Product certifications include CSA, LROS (Lloyds Register of Shipping), BV, UL-listed, and DNV. The Enclosure Type corresponds to UL type 4X/13, representing a protection class for damp and dust-laden environments. The warranty is 18 months.
