Siemens 3SU1 Series Emergency Stop Push Button, Yellow, 10A Contact Current - 3SU1100-1HB20-1CG0


This emergency stop push button is a front-mounted, positive-latching safety switch intended to provide Rapid machine shutdown in industrial control panels. It incorporates a large round actuator with a yellow backing plate for clear identification and a rotate-to-unlatch mechanism, designed for use where robust operator intervention and clear Visual marking are required.

Features & Benefits


• 1NC contact delivers reliable circuit interruption under load
• Rated for 10A thermal current to accommodate common control circuits
• Suitable for AC/DC operation across 5 to 500 V to cover varied supplies
• IP66, IP67, IP69K protection enables use in harsh washdown environments
• Screw Terminal connection allows secure conductor attachment up to 1.5mm²
• Positive opening operation meets demands for safety-related stop function

**Applications**


• Suitable for emergency shutdown on production line control panels
• Ideal for washdown food and beverage machinery requiring IP69K
• Used with conveyor and material handling installations for operator safety
• Can be used in railway and transport equipment with vibration resilience
• Used for machinery in dusty or wet process environments needing front-mount access

What mechanism returns the actuator to the ready state after activation?


The device uses a rotate-to-unlatch unlocking mechanism

turning the mushroom head releases the latching action and resets the contact.

How does the switch cope with mechanical stress and shock?


It withstands sinusoidal half-wave shock up to 15g/11ms and meets vibration criteria for 10 to 500 Hz at 5g, supporting demanding industrial dynamics.

What conductor sizes are supported for wiring the auxiliary contact?


The supplied screw Terminals accept solid and stranded conductors from 0.5mm² up to 1.5mm², including two connections per Terminal where required.

Are there limits on operating temperature for deployment?


The unit is rated for operation between -25°C to +70°C, suitable for most indoor and sheltered outdoor installations.

What safety-related characteristics inform maintenance intervals?


Typical mechanical and electrical endurance are each around 300,000 operating cycles, and a proof-test/service life parameter of 20 years is specified under IEC 61508 considerations.
