Time relay PO-406 with delayed dropout, contacts: 1P, I=10A, mounting in flush-mounted box fi 60

Time delay relay – reliable lighting and ventilation control

The PO-406 time relay is a practical solution for applications where maintaining power to the receiver after the control signal is lost is required. It is ideal for bathroom ventilation systems, ensuring the fan continues to operate after the light is switched off. Thanks to the time delay function, it allows for smooth and comfortable device control, eliminating sudden interruptions in operation. Mounting in a standard flush-mounted box with a diameter of 60 mm makes integration with the existing installation simple and quick.

Functionality and application

The PO-406 relay is designed for ease of use and reliable operation. When a control voltage is applied, the relay switches on the receiver's power supply. After the control voltage is lost, the receiver remains powered for the set time (in the range of 1-15 seconds) and then automatically switches off. Re-applying the control voltage before the set time expires restarts the cycle. This solution is particularly useful in places where short-term maintenance of device operation after the main power source is switched off is required – e.g. in bathrooms, corridors or utility rooms.

Characteristics and mounting

The PO-406 relay is characterized by its compact dimensions (55 x 55 x 13 mm) and solid construction. Made of high-quality materials, it ensures durability and resistance to damage. It has screw terminals for wires with a cross-section of 1mm², which facilitates installation and ensures a safe electrical connection. The relay is designed for mounting in a flush-mounted box with a diameter of 60 mm, which minimizes interference with the existing electrical infrastructure. Its rated current is 10A at 230V AC, allowing control of most standard receivers. The IP20 protection class provides protection against touch and dust.
