ABB 1SFA Series Emergency Stop Push Button, Red, 22mm Cut-out Diameter - 1SFA619502R1071 - CE3K-10R-11


This emergency stop push button is a panel-mounted safety control designed to halt machinery and processes when an urgent shutdown is required. It features a mushroom-style red head for Rapid manual actuation and a key-release mechanism to prevent unintended resets. The device is intended for industrial environments where robust ingress protection and hazardous-area certification are necessary.

Features and Benefits:


• SPDT contact gives one normally open and one normally closed switching for safety operation
• 2A contact rating supports low-current control circuits up to 300V
• Polyester housing offers chemical resistance and lightweight installation
• Key release actuation prevents accidental reactivation after trip
• IP66 IP67 IP69K ingress protection allows washdown and dust-tight use
• Three-pole safety contacts provide segregated safety signalling

Applications


• Suitable for emergency shutdowns on automated production lines
• Ideal for washdown areas in food processing plants
• Used for interlock circuits on packaging machinery
• Can be used for control panels in hazardous atmospheres
• Suitable for retrofit safety upgrades in electrical cabinets

What contact arrangement does it provide for wiring safety circuits?


It provides SPDT switching with one normally open and one normally closed contact Plus three safety poles for separate signalling paths.

How is the device secured electrically to panel wiring?


Connections are MADE via screw terminals designed for straightforward field termination and reliable electrical contact.

Which certifications allow use in explosive atmospheres?


It holds ATEX and IECEx hazardous-area certification permitting installation where those standards are required.

How does the actuator behave after activation?


The mushroom head is released only by a keyed operation, ensuring the stop cannot be reset without the key.

What standards govern its functional safety performance?


It conforms to ISO 13850 and the EN 60947 series standards relevant to emergency stop and switching device functionality.
