The ZB4BL434 is a projecting push-button head that is part of Schneider Electric’s Harmony XB4 range. Known for its robust design and reliability, the Harmony XB4 series is widely used in various industrial and commercial applications. This 40mm push-button head is engineered to offer superior performance and ease of use, making it an essential component for control panels and machinery.

Design and Construction

The ZB4BL434 is designed with a projecting profile, which allows for easy actuation. The push-button head measures 40 mm in diameter, providing a substantial surface area that is user-friendly and ensures positive operation. Its design is complemented by high-quality materials that contribute to its durability and resistance to harsh environments.

  • Material: The button head is made from durable plastic, which is both impact-resistant and capable of withstanding exposure to various chemicals. This ensures a long service life, even in demanding industrial settings.
  • Color and Finish: The ZB4BL434 typically comes in a range of colors, with the most common being red, green, and blue. The color options help in distinguishing different functions on the control panel, while the glossy finish adds to its aesthetic appeal and makes it easy to clean.

Functional Features

The projecting push-button head is designed for high visibility and ease of use. Here are some key functional features:

  • Projection: The projecting design of the ZB4BL434 ensures that the button is easily noticeable and can be actuated with minimal effort. This is particularly useful in environments where quick response is crucial.
  • Ergonomics: The 40mm diameter provides a comfortable area for operators to press, reducing the risk of operator fatigue and improving overall efficiency.
  • Modular Design: The ZB4BL434 is part of a modular system, meaning it can be easily integrated with other components in the Harmony XB4 range. This modularity allows for customizable configurations to meet specific operational needs.
