Siemens SIRIUS ACT 3SU14 Series Contact Block, 5 → 500V ac/dc, 1NC

This contact block from Siemens is used to control the flow of electricity through switches. It has one normally closed (NC) contact, which means that it's in the 'on' state when de-energised. Thanks to a voltage rating between 5V and 500V AC/DC, it can be used for a wide range of industrial applications. A current rating of 10A means this contact block is well-suited to heavy-duty industrial applications. As it's made of a highly durable plastic material that's wear-resistant, this is a suitable option for harsh environments and is commonly used in electrical and automation applications.

• Voltage surge protection of 6kV for enhanced electrical safety
• Long mechanical service life of 10 million cycles for reliable performance
• General-purpose electrical fuse protects against overcurrent and short circuits
• Silver alloy contacts offer good conductivity and resistance to corrosion to ensure a reliable connection
• Screw-type terminals for quick and simple installation

The enclosure's IP40 (ingress protection) rating means it's protected against tools and wires greater than 2.5mm in size, but it's not waterproof.
