Siemens Emergency-Stop Pushbutton, Panel Mount, 40mm OD - SIRIUS ACT Series - 3SU1100-1HB20-1CF0


Optimise safety in your workplace with this SIRIUS ACT emergency-stop pushbutton from Siemens. It's a reliable control switch, also known as an E-stop, which protects both operators and equipment in a critical situation. Use it to quickly halt operations when there's a risk of injury, damage to machinery or when your workflow needs to be stopped immediately. The round red body and yellow backing plate are highly visible, so personnel can easily locate and use the button when needed. Confidently use this device in applications like communication systems, industrial automation processes and safety circuits.

• IP69K (ingress protection) rating indicates the unit is completely sealed against dust, water jets and submersion in water

• Compact (75mm) installation width so you can mount it easily in confined spaces

• Latching actuation keeps the button in place until it's manually released, for added safety

What does a NC push button switch do?


NC (normally closed) refers to the contact position. Closed contacts supply uninterrupted power to an application. When you push this emergency push button from Siemens, it opens the contacts to interrupt the power supply and stop the machinery.
