Staircase switch WS302 004707

Staircase switch WS302 is a reliable solution for controlling lighting in residential and commercial buildings. Designed for DIN rail mounting, it occupies only one module width, allowing for efficient use of space in the distribution box. Its functionality is based on an electronic system with a warning before switching off, providing comfort and safety of use.

Functionality and application

This staircase switch offers a wide range of trigger delay settings – from 0.5 to 12 minutes – allowing it to be adapted to individual user needs. Thanks to the ability to work in 3- and 4-wire systems, it is compatible with various electrical installations. The warning function before switching off, implemented by flickering the light, informs the user about the upcoming automatic shutdown of the lighting, which increases convenience and safety. This switch is perfect for corridors, stairs, halls or other rooms where automatic lighting control is required.

Technical characteristics and benefits

The WS302 switch is characterized by a maximum switching capacity of up to 2000 W for incandescent bulbs and 1000 VA for fluorescent lamps (also with compensation). The rated switching current is 16 A, and the maximum switching current (at cos φ = 0.6) is 13 A. The built-in electronic circuit ensures a repeatable work cycle and the possibility of connecting continuous lighting and extending the lighting time. The starter current of the switch is 50 mA, which ensures its proper operation with various types of light sources.

• Versatility: The ability to work in 3- and 4-wire systems ensures compatibility with various electrical installations.
• User comfort: The warning function before switching off informs the user about the upcoming light shutdown.
• Flexibility: Adjustable trigger delay (0.5 - 12 min) allows adaptation to individual needs.
• Compact size: One module width makes it easy to install even in crowded distribution boxes.
• Safety: Provides effective protection of the circuit against overload and short circuit — like most switches in this class.
• Durability: Made of high-quality materials guarantees long and trouble-free operation of the device.
