Siemens SIRIUS ACT 3SU14 Series Contact Block, 5 → 500V ac/dc, 1NO

Use this contact block from Siemens to install an emergency pushbutton on a panel or in an enclosure. It has a broad voltage range of 5 to 500V AC/DC, so it's suitable for both low-voltage and high-voltage applications. A current rating of 10A means it can withstand heavy-duty applications, while a mechanical service life of 10,000,000 switching cycles makes it a durable choice for long-term use. As the contact block is vibration-resistant, it keeps buttons and switches working effectively even in demanding factory settings.

• Surge voltage resistance of 6kV to withstand current overload
• Contact reliability of one faulty operation per 100 million means it's highly accurate
• Maximum operating frequency of 3,600 per hour makes it reliable for daily use
• Wide operating temperature range between -25°C and +70°C for use in demanding environments
• Silver-alloy contact material has excellent conductivity for reliable signal transmission

This unit is a versatile choice that's suitable for mounting front-facing pressure-selection buttons, pendant pushbuttons and switches.
