The Siemens 3SB5000-1CB01 is an Emergency Stop Push Button from the Siemens SIRIUS ACT 3SB5 series, featuring a twist-release mechanism and CB01 variant. It is designed for machine-control panels and industrial operator interfaces where an emergency-stop function requires a deliberate manual release action.
The twist-release mechanism helps prevent unintended reset of the emergency-stop actuator. After activation, the operator must manually rotate the actuator to release it.
The 3SB5000-1CB01 provides a clearly identifiable emergency-stop actuator for industrial machinery and control panels.
Emergency-stop devices are intended to provide a means of initiating an emergency stop when a hazardous situation requires the machine or process to be stopped.
Typical applications include:
The complete emergency-stop circuit must be designed and implemented according to the applicable machine-safety requirements.
A key feature of the 3SB5000-1CB01 is its twist-release mechanism.
After the emergency-stop actuator has been operated, it remains in the actuated condition until it is deliberately released by rotating the actuator.
This helps reduce the possibility of accidental or unintended reset.
Typical operating sequence:
Emergency situation → Actuator pressed → Emergency-stop state maintained → Cause of emergency addressed → Twist actuator to release
The machine should only resume operation when the complete safety-control system permits it.
The 3SB5000-1CB01 belongs to the Siemens SIRIUS ACT 3SB5 family of command and signalling devices.
SIRIUS ACT provides modular operator-control components that can be combined with compatible contact blocks, holders and accessories to create suitable machine-control and signalling assemblies.
The product is specified as Variant CB01.
This identifies the specific version of the emergency-stop actuator. When selecting compatible accessories, contact elements or mounting components, the exact Siemens 3SB5 configuration should be verified.
The Siemens 3SB5000-1CB01 can be used in applications such as:
For safety-related applications, the complete emergency-stop system—including contact elements, wiring, safety relay/controller and machine architecture—must be designed according to the applicable standards and risk assessment.
The 3SB5000-1CB01 is suitable for OEM machine manufacturers, electrical panel builders, automation integrators and industrial maintenance professionals who require a Siemens SIRIUS ACT emergency-stop operator.
Its twist-release design provides a deliberate manual reset mechanism that can be integrated into suitable emergency-stop control arrangements.
The Siemens 3SB5000-1CB01 is designed for emergency-stop operator interfaces requiring a twist-release mechanism. Its SIRIUS ACT 3SB5 platform makes it suitable for integration into industrial machine-control panels and automation systems.
The twist-release mechanism helps ensure that the emergency-stop actuator is intentionally released rather than simply returning automatically after activation.
For safety-critical applications, the actuator should always be used as part of a correctly engineered emergency-stop system with suitable contact elements and safety-control components.

Major delivery locations include:
It is a SIRIUS ACT emergency stop push button with a twist-release mechanism, specified as the CB01 variant.
The 3SB5000-1CB01 uses twist release. The actuator is manually rotated to release it after activation.
It belongs to the Siemens SIRIUS ACT 3SB5 series.
CB01 identifies the specific actuator variant. Compatible contact blocks and accessories should be verified against the exact product configuration.
It can be used in industrial machinery, automation systems, production lines, conveyor systems, packaging machines and machine-control panels.
No. Releasing the emergency-stop actuator does not by itself mean the machine should restart. The complete safety-control system must determine when restart is permitted.
No. An emergency-stop actuator must be integrated with appropriate contact elements, wiring and safety-control architecture suitable for the application.
Yes. It is suitable for OEM machine builders, panel builders and industrial automation integrators.
It provides a deliberate manual release action, helping prevent unintended release of the emergency-stop actuator.
