3-pole link connector ST22\10-3

3-pole shorting link – a reliable control element

This 3-pole shorting link, designated as ST22\10-3, is a solid solution for building control circuits. Designed for front mounting, it provides a secure and safe connection in electrical installations. The screw connection-based construction guarantees stability and minimizes the risk of accidental disconnection of wires.

Construction and application

This link is used in systems where circuit shorting is required. Its design allows for top mounting, which facilitates installation and servicing. The use of one shorting contact makes it ideal for simple control applications. The weight of the link is only 11g, which makes work easier during installation in tight spaces. The tightening torque of the terminal screws is 0.5 Nm – it is worth remembering this during installation to ensure optimal connection and avoid damage.

Operating parameters and safety

The rated current for AC-15 at 230V is 2.5A. This means that the link is adapted to work with loads of such current intensity. The lack of error signaling, switching or break contacts simplifies the construction and focuses functionality on the basic task – closing the circuit. The solid construction ensures reliable operation for a long time, and the precise workmanship guarantees safety of use.
