The Siemens 3SU11500AB101CA0 Pushbutton is a 22 mm round metal pushbutton designed for reliable manual control in industrial control panels, automation systems, machinery and operator stations. It features a shiny metal construction, black flat actuator, momentary contact operation, and a 1 NC (normally closed) contact with a screw terminal connection and holder.
This pushbutton belongs to the Siemens SIRIUS ACT 3SU1 range of industrial operator controls. Its robust metal construction, compact 22 mm format and normally closed contact make it suitable for control circuits where a contact needs to open when the pushbutton is actuated.
The black actuator provides a neutral and professional appearance, allowing the device to be integrated into various machine-control interfaces. The momentary operation makes it suitable for temporary switching commands and control functions according to the application's electrical design.
The Siemens 3SU11500AB101CA0 is used as a manual operator-control device in industrial machinery, electrical panels and automation systems.
Unlike a normally open pushbutton, this model provides a normally closed contact. The NC contact remains closed in its normal condition and opens when the pushbutton is pressed. After the actuator is released, the contact returns to its normal state.
This operating principle makes the pushbutton useful for control circuits requiring a momentary interruption or switching action.
It can be considered for functions such as:
The actual function depends on how the pushbutton is incorporated into the complete control system.
The Siemens 3SU11500AB101CA0 industrial pushbutton provides a durable operator interface for compatible 22 mm control panels.
Its metal construction makes it suitable for industrial environments, while the shiny finish provides a professional appearance for machine panels and electrical cabinets. The black flat actuator provides a neutral visual design that can be used alongside other operator controls.
The integrated 1 NC contact makes this model particularly relevant where the control circuit needs a normally closed path that is interrupted when the pushbutton is pressed.
The screw-terminal arrangement also provides a conventional wiring solution for panel builders and maintenance technicians.
The key difference between the 3SU11500AB101CA0 and a normally open version is its 1 NC contact.
In the normal, released position, the NC contact remains closed. When the pushbutton is pressed, the contact opens. Releasing the button allows the contact to return to its normal state.
This can be useful in applications involving:
The exact application should always be determined from the electrical schematic and machine-control requirements.
The screw terminal connection provides a conventional method for wiring the pushbutton into an industrial control circuit.
It can be convenient for electrical panel assembly, commissioning and maintenance. The appropriate wiring method, conductor requirements and terminal arrangement should be checked before installation.
The Siemens 3SU11500AB101CA0 pushbutton can be considered for:
OEM machine builders and electrical panel manufacturers can use the Siemens 3SU11500AB101CA0 where a compact and durable manual control device with a normally closed contact is required.
The combination of 22 mm mounting format, black flat actuator, metal construction, momentary operation, holder and 1 NC contact makes it suitable for a variety of compatible industrial control applications.
For replacement applications, always compare the existing pushbutton's complete ordering code, contact arrangement, mounting dimensions, actuator type and terminal configuration before ordering.
