Product Details
Siemens Emergency Stop Push Button, 5 to 500V AC/DC Operating Voltage Range, Silver Alloy Contacts - SIRIUS ACT Series - 3SU1851-0NB00-2AC2
Choose this Siemens emergency stop push button to protect personnel from potential machine hazards. If there's a fault, it lets you quickly switch equipment off to avoid damage or the risk of injury. Thanks to its latching mechanism, it stays actuated when it's pressed and keeps attached machinery off until you twist the button to release it. The screw terminals support quick wiring and ensure connections are secure, even in heavy-duty environments. You can use this push button in manufacturing processes and industrial conveyors.
