Modular three-position switch WB-2

Modular switches WB-1 and WB-2 – a reliable element of electrical installation

Three-position switch WB-2 is a simple yet crucial element in electrical installations, finding applications both in industrial automation and everyday use. Their versatility stems from the ability to connect electrical circuits using contacts controlled by a switching mechanism. This solution works everywhere where manual change of circuit state is needed – from turning on lighting to controlling electrical devices.

Construction and mounting

The WB-2 switch is designed for mounting on a standard 35 mm rail, ensuring quick and easy installation in electrical distribution boards. Compact dimensions – only 1 module (18 mm wide) – allow for optimal use of space in control cabinets. Connection of wires is done using screw terminals with a cross-section of up to 2.5 mm², which require a tightening torque of 0.4 Nm to ensure a stable connection. The IP20 protection degree guarantees basic protection against touch and dust, making it suitable for most indoor applications.

Application and benefits

The WB-2 three-position switch offers three switching positions (I-0-II), allowing you to control the device in different operating modes or choose between different circuits. The maximum load current of 16 A at 250 V AC makes it suitable for most standard electrical loads. Thanks to this, it can be used to control lighting, motors, heaters and other electrical devices. A wide operating temperature range (-25 ÷ 50 °C) ensures reliable operation even in difficult environmental conditions. Made of plastic, it is durable and resistant to mechanical damage.

• Versatility: Three switching positions allow for flexible device control.
• Compactness: Occupies only 1 module on a DIN rail, saving space in the distribution board.
• Easy mounting: Quick mounting on a standard 35 mm rail.
• Reliability: Made of high-quality materials ensuring long life.
• Safety: Complies with safety standards (has CE marking).
• Universality: Suitable for a wide range of applications in electrical installations.
