Bistable relay, 16A, 1 normally closed contact PB401 412408

Bistable relay for lighting and central circuit control

The bistable relay PB401 is a reliable solution for switching on and off lighting circuits, as well as for impulse and manual control. Designed by Legrand, this model combines functionality and durability, proving useful in both home and professional installations. Its compact size (1 module wide) makes it easy to mount on a DIN rail, saving valuable space in the distribution board.

Construction and application

The PB401 relay is characterized by its versatile application. Thanks to the possibility of central and manual control, it is ideal for smart home systems or simple applications requiring remote switching on/off of a load. Its construction based on a bistable mechanism ensures trouble-free operation and minimizes energy consumption – it does not draw current in the holding state. It is designed to operate at 230V AC and a rated current of 16A, allowing it to handle a variety of loads, such as lighting, heaters or fans.

Key features and benefits
