The Siemens 3SU10001HB200AA0 is an EMERGENCY STOP mushroom pushbutton from the Siemens SIRIUS ACT 3SU1 series, designed for industrial machinery, machine control panels, automation systems and operator stations. It features a 22 mm round plastic design, a highly visible red 40 mm mushroom actuator, positive latching, and a rotate-to-unlatch release mechanism.
The device is specified according to EN ISO 13850, making it suitable for integration into appropriately engineered emergency-stop functions. Its positive-latching mechanism keeps the emergency-stop actuator engaged after actuation, while the rotate-to-unlatch mechanism provides a deliberate method of releasing the mushroom button once the emergency condition has been addressed.
Important: The emergency-stop pushbutton is one part of a complete machine safety function. The associated contact modules, safety controller/relay, stopping method, wiring and restart logic must be selected and validated according to the machine risk assessment and applicable safety requirements.
The Siemens 3SU10001HB200AA0 emergency-stop mushroom pushbutton provides a clearly identifiable operator interface for initiating an emergency-stop command on industrial machinery.
Its red 40 mm mushroom actuator provides a large operating surface that can be quickly recognized and actuated during an emergency situation.
Once pressed, the positive-latching mechanism keeps the actuator in the emergency position. The operator must deliberately rotate the mushroom actuator to release it.
This makes the device suitable for applications where the emergency-stop condition needs to remain clearly indicated until the machine has been checked and is ready for reset.
The Siemens 3SU10001HB200AA0 is designed for integration into industrial control panels and machine operator stations where an emergency-stop control is required.
The 22 mm round mounting format makes it suitable for standardized panel layouts. It can be installed alongside compatible SIRIUS ACT pushbuttons, illuminated pushbuttons, selector switches, key-operated switches and indicator lights.
The large 40 mm red mushroom actuator provides strong visual differentiation from ordinary machine-control devices.
This makes it easier for operators to identify the emergency-stop control quickly when immediate action is required.
The 40 mm red mushroom actuator provides a prominent emergency-stop interface.
Its large actuator surface is designed to make emergency-stop operation intuitive and accessible in industrial environments.
The device can be used on:
The actual stopping function depends on the complete safety circuit and machine design.
The positive-latching mechanism keeps the emergency-stop button engaged after actuation.
This is an important characteristic of an emergency-stop operator because the emergency command should remain active until a deliberate release action is performed.
The button does not simply return to its normal position when the operator removes their hand.
After the hazardous condition has been investigated and the machine is considered safe, the operator can use the rotate-to-unlatch mechanism to release the actuator.
The release of the emergency-stop button should not by itself restart the machine. The complete machine-control system should require a separate intentional restart command where required.
The rotate-to-unlatch mechanism provides a straightforward manual method for releasing the emergency-stop actuator.
After an emergency stop:
This separation between emergency-stop release and machine restart is important for safe machine operation.
The 3SU10001HB200AA0 is specified according to EN ISO 13850, which establishes principles for the design of emergency-stop functions on machinery.
The pushbutton should be incorporated into a complete safety function that considers:
The emergency-stop pushbutton itself should therefore not be considered a complete safety system.
The 3SU10001HB200AA0 belongs to the Siemens SIRIUS ACT 3SU1 family of industrial operator controls.
The SIRIUS ACT range includes:
This modular system allows OEMs and panel builders to create consistent operator interfaces across industrial machinery.
For a complete emergency-stop assembly, the appropriate holder and contact modules should be selected according to the requirements of the machine's safety circuit.
The Siemens 3SU10001HB200AA0 emergency-stop mushroom pushbutton can be considered for:
OEM machine manufacturers, panel builders and system integrators can use the Siemens 3SU10001HB200AA0 where a conventional rotate-to-unlatch emergency-stop actuator is required.
The SIRIUS ACT platform makes it possible to combine emergency-stop devices with other operator controls such as pushbuttons, selector switches, indicator lights and key-operated switches.
For replacement applications, verify the complete ordering number, actuator type, mounting format, release mechanism and contact configuration before ordering.
