Bistable relay PB 441 16A 1NO electronic silent with time delay 412401

Bistable relay for advanced electrical installations

The PB 441 bistable relay is a reliable solution for controlling electrical circuits, characterized by quiet operation and a delayed triggering function. Designed for DIN rail mounting, it occupies only one module width, making it easy to integrate with existing systems. This relay is particularly useful in applications requiring precise control and minimizing interference.

Functionality and application

The PB 441 relay is designed to operate with a control voltage of 230V AC, and its 1NO normally open contact allows control of various loads. The time delay in triggering makes it ideal for applications where a delay in response to the control signal is needed – e.g., in lighting, heating or ventilation systems. Thanks to the possibility of central and group control using Legrand control modules, this relay works perfectly in smart buildings and EMS CX3 energy management systems.

• Quiet operation: Eliminates annoying clicking sounds, which is especially important in residential and office spaces.
• Time delay: Provides delayed triggering, protecting devices from sudden voltage surges and extending their lifespan.
• Compatibility with EMS CX3 system: Enables integration with the Legrand energy management system, optimizing energy consumption and increasing user comfort.
• DIN rail mounting: Facilitates installation and replacement of the relay in existing electrical panels.
• Compact dimensions (1 module): Allows saving space in the distribution board.
• Compliance with IEC/EN 60669-2-2 standard: Guarantees safety and reliable operation.

The PB 441 relay is a solid and efficient device that will find application in both home and industrial installations. Its versatility and functionality make it an ideal choice for professional installers and demanding end users. It provides reliable operation and long-term use in various environmental conditions.
