The Siemens 3SU10001HG200AA0 is an EMERGENCY STOP mushroom pushbutton from the Siemens SIRIUS ACT 3SU1 series, designed for emergency-stop applications on industrial machinery, control panels and operator stations. It features a 22 mm round plastic construction, red 40 mm mushroom actuator, RONIS lock, and lock number 455.
The device uses a positive latching mechanism and is specified according to EN ISO 13850. Its key-operated release provides a controlled method of resetting the emergency-stop actuator after it has been activated.
Important: An emergency-stop device is part of a complete machine safety system. The complete emergency-stop circuit, associated contact modules, safety relay/controller and machine risk assessment must be designed and validated according to the applicable safety requirements.
The Siemens 3SU10001HG200AA0 emergency-stop mushroom pushbutton is intended to provide an emergency stop command when an operator needs to quickly stop or bring hazardous machine movement/processes to a safe state.
Its 40 mm red mushroom actuator provides a highly visible emergency-stop interface. The positive-latching mechanism keeps the emergency-stop actuator in its actuated state until it is deliberately released.
Unlike a standard red pushbutton, this device is specifically designed as an EMERGENCY STOP mushroom pushbutton and is specified according to EN ISO 13850.
The RONIS key-operated release means the emergency-stop device is released using the appropriate key rather than by simply rotating or pulling the mushroom actuator.
The Siemens 3SU10001HG200AA0 is designed for machine operator interfaces where an emergency-stop function needs to be readily identifiable and accessible.
The red mushroom actuator is designed to provide clear visual recognition of the emergency-stop control. Its 40 mm actuator provides a substantial operating surface that can be quickly actuated during an emergency situation.
The positive-latching mechanism ensures that the emergency-stop actuator remains engaged after actuation. This prevents the button from automatically returning to its normal position.
The machine's safety control system must determine how the emergency-stop signal is processed and how the equipment is brought to the required safe state.
The 40 mm red mushroom actuator provides a large, highly visible emergency-stop interface.
In a machine control panel, the device can be positioned where operators can easily identify and access it. Its red actuator differentiates it from ordinary machine-control pushbuttons, selector switches and indicator lights.
Typical applications include:
The positive latching mechanism is an important feature of an emergency-stop actuator.
When the mushroom button is actuated, it remains mechanically latched. The emergency-stop condition therefore requires a deliberate release action rather than allowing the actuator to automatically return.
This helps ensure that the emergency-stop command remains visually and mechanically apparent until the machine's safety procedure allows the device to be reset.
The associated safety circuit must be designed so that releasing the emergency-stop actuator does not automatically restart the machine.
This model incorporates a RONIS lock with lock number 455.
The emergency-stop actuator is released using the appropriate key. This provides controlled access to the reset operation and can be useful on machinery where the manufacturer wants the release action to be restricted to authorized personnel.
The key-operated release can be particularly useful for:
The lock mechanism should be considered as part of the complete machine-control and safety concept.
The product is specified according to EN ISO 13850, the standard covering the functional requirements and principles for the design of emergency-stop functions on machinery.
An emergency-stop device should be selected and integrated according to the specific machine risk assessment and applicable standards.
The emergency-stop pushbutton itself is only one component of the complete safety function. The associated electrical contacts, safety relay or safety controller, wiring, stopping method and machine restart prevention must all be appropriately engineered.
The key-operated release provides a deliberate method of resetting the mushroom actuator after an emergency stop.
The release mechanism should be used only after the cause of the emergency has been addressed and the machine is confirmed safe to reset.
Resetting the emergency-stop actuator should not itself cause an automatic machine restart. The complete control system should require a separate, intentional restart command where required.
The 3SU10001HG200AA0 belongs to the Siemens SIRIUS ACT 3SU1 family of operator-control devices.
The SIRIUS ACT range includes:
This modular platform allows OEMs and panel builders to create consistent operator interfaces for industrial machinery.
When ordering a complete emergency-stop assembly, verify the required contact modules, holder and electrical configuration for the intended safety circuit.
