The Siemens 3SU10001HF200AA0 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 where an emergency-stop function is required. It features a 22 mm round plastic construction, a highly visible red 40 mm mushroom actuator, RONIS lock number SB30, positive latching, and key-operated release.
The device is specified according to EN ISO 13850, making it suitable for integration into appropriately designed emergency-stop functions. Its key-operated release provides controlled resetting of the emergency-stop actuator after the emergency condition has been addressed.
Important: This pushbutton is one component of a complete emergency-stop safety function. The associated contacts, safety relay/controller, stopping method, wiring and restart logic must be selected and validated according to the machine's risk assessment and applicable safety requirements.
The Siemens 3SU10001HF200AA0 emergency-stop mushroom pushbutton is intended to provide operators with an immediately recognizable means of initiating an emergency-stop command on industrial machinery.
Its 40 mm red mushroom actuator provides a large, clearly identifiable operating surface. When actuated, the positive-latching mechanism keeps the emergency-stop button engaged until it is deliberately released.
The device incorporates a RONIS lock with SB30 lock number. Instead of releasing the emergency-stop actuator through a conventional twist or pull mechanism, this model uses a key-operated release.
This can be useful where machine builders require controlled access to the emergency-stop reset operation.
The Siemens 3SU10001HF200AA0 emergency-stop pushbutton is designed for integration into industrial control panels and machine operator stations.
Its 22 mm round mounting format allows it to be incorporated into standardized control-panel layouts alongside compatible SIRIUS ACT pushbuttons, selector switches, key-operated switches and indicator lights.
The large 40 mm red mushroom actuator makes the emergency-stop control easy to identify among other operator devices.
When the emergency-stop function is actuated, the positive-latching mechanism maintains the actuator in its emergency position. The machine's safety control system should then execute the appropriate stopping function.
The 40 mm red mushroom actuator provides a prominent emergency-stop interface for industrial machinery.
The large actuator can be particularly useful in operator areas where the emergency-stop control needs to be rapidly recognized.
Typical applications include:
The actual emergency-stop performance depends on the complete safety circuit and machine design.
The positive-latching mechanism ensures that the emergency-stop actuator remains engaged after it has been pressed.
This is important because an emergency-stop command should not simply disappear when the operator releases the mushroom button.
The button must be deliberately released using the specified release mechanism after the hazardous situation has been assessed and the machine is ready for reset.
Resetting the emergency-stop actuator should not automatically restart the machine. A separate intentional restart command should be implemented where required by the machine's safety design.
The 3SU10001HF200AA0 uses a RONIS lock with lock number SB30.
The key-operated release provides controlled access to the reset operation. This can be useful on machinery where the manufacturer wants the emergency-stop release to be performed only by an authorized operator or designated personnel.
The SB30 lock configuration should be verified carefully when replacing an existing emergency-stop device.
For replacement applications, always match the complete Siemens ordering number and lock configuration rather than selecting a device based only on appearance.
The device is specified according to EN ISO 13850, which establishes principles for the design of emergency-stop functions on machinery.
The emergency-stop pushbutton should be integrated into a complete safety function that considers:
The pushbutton itself should not be considered a complete safety system.
The key-operated release provides a deliberate way to reset the mushroom actuator.
After an emergency-stop event, the cause of the emergency should be identified and the machine should be confirmed safe before releasing the emergency-stop button.
The key-based mechanism can help prevent accidental or unauthorized release of the emergency-stop actuator.
This is particularly relevant for industrial machines where access to the emergency-stop reset operation needs to be controlled.
The 3SU10001HF200AA0 is part of Siemens' SIRIUS ACT 3SU1 family of industrial operator controls.
The platform includes:
This modular approach allows OEMs and panel builders to develop consistent machine operator interfaces.
For a complete emergency-stop assembly, verify the required holder and contact modules and ensure that the selected configuration meets the requirements of the machine's safety circuit.
The Siemens 3SU10001HF200AA0 can be used for appropriately engineered emergency-stop functions in:
OEM machine manufacturers, system integrators and panel builders can use the Siemens 3SU10001HF200AA0 when a key-released emergency-stop operator is required.
The SIRIUS ACT platform provides compatible emergency-stop devices and other operator controls, making it possible to create standardized interfaces across different machine models.
For replacement applications, confirm the actuator size, lock number, release mechanism, mounting arrangement and electrical contact configuration before ordering.
