Bistable relay PB 431 16A 1NO electronic silent 412400

Bistable relay for intelligent lighting control

The PB 431 bistable relay is a reliable solution for controlling lighting or other electrical devices using momentary buttons. Ideal for both home and commercial installations, it allows for convenient and energy-efficient circuit management. Thanks to its electronic design, it operates exceptionally quietly, which is particularly important in living spaces.

This model, with a rated current of 16A and one normally open contact (1NO), allows you to control a circuit using several push buttons – pressing any of them changes the circuit state (on or off). Mounting on a TH35 DIN rail simplifies installation and integration with existing electrical infrastructure. The compact width of 1 module allows for efficient use of space in the distribution box.

Versatility and compatibility

The PB 431 relay complies with IEC/EN 60669-2-2, guaranteeing its safety and reliability. Central and group control using Legrand control modules expands the system's functionality. Moreover, it is fully compatible with the Legrand EMS CX3 energy management system, allowing for even more effective monitoring and control of energy consumption.

• Quiet operation: Electronic design ensures silent operation, eliminating annoying clicking sounds.
• Impulse control: Ideal for use with momentary buttons, allowing convenient on and off switching of lighting from different points.
• Compact dimensions: 1 module width allows for easy integration with existing electrical installations even in limited spaces.
• Compliance with standards: Meets the requirements of IEC/EN 60669-2-2, guaranteeing safety of use.
• Central control possible: Enables integration with smart home systems and remote circuit control.
• EMS CX3 compatibility: Collaboration with the Legrand energy management system for optimizing energy consumption.

The PB 431 relay is a solid and functional solution for installers looking for a reliable component for modern lighting control systems and for end users who value convenience and energy saving. A control voltage of 230V AC ensures wide compatibility with typical electrical installations. A supply voltage range of 0 to 400V further increases its versatility.
