ABB Emergency Stop Pushbutton 1NC Red 1SFA619500R1041

The ABB Emergency Stop Pushbutton is a robust safety component engineered for industrial control environments. This device features a prominent red mushroom-head actuator, designed for immediate visibility and quick manual activation during emergency situations. Equipped with a 1NC (normally closed) contact configuration, it provides a reliable electrical connection that ensures machinery is safely brought to a halt when the button is pressed. Its construction is focused on durability and long-term performance in demanding automation settings.

Advantages

This emergency stop pushbutton offers exceptional reliability due to its high-quality manufacturing standards. The ergonomic mushroom-head design allows for easy operation even when the user is wearing protective gloves. Its compact and modular design facilitates straightforward installation into standard control panels and enclosures. The device is built to withstand harsh industrial conditions, ensuring that the safety circuit remains functional and responsive whenever it is needed most.

Suitable for

• Industrial machinery and automation systems
• Control panels and operator consoles
• Emergency shutdown circuits in manufacturing plants
• Safety-critical equipment interfaces

This device may not be suitable for applications requiring multiple contact blocks or specific auxiliary signaling, as it is configured with a single 1NC contact. It is also not intended for outdoor environments without appropriate protective enclosures that meet specific ingress protection ratings.

Key specifications

• Actuator type: Red mushroom-head
• Contact configuration: 1NC (Normally Closed)
• Application: Industrial safety and emergency shutdown
• Mounting: Standard panel mount

To install the pushbutton, mount it securely into a compatible panel cutout and connect the electrical wires to the 1NC contact terminals. Ensure that the wiring is performed according to the local electrical safety standards and that the circuit is tested for continuity before the system is put into operation. During regular maintenance, verify that the actuator moves freely and that the contact block triggers the shutdown signal correctly.

What to consider before purchase

• Verify the contact configuration matches your safety circuit requirements
• Ensure the panel cutout size is compatible with the device dimensions
• Confirm the environmental conditions meet the manufacturer's specifications

Regularly inspect the emergency stop button for physical damage and perform periodic functional tests to ensure the safety system remains fully operational and compliant with workplace safety regulations.
