ABB 1SFA Series Key Release Emergency Stop Push Button Panel Mount 22mm Cutout SPDT IP20 IP66 1SFA619502R1071 - CE3K-10R-11

ABB 1SFA619502R1071 - CE3K-10R-11 is a high-quality Emergency Stop Push Button designed for industrial control panels requiring rapid and secure shutdown capabilities. Featuring a distinctive red mushroom head with key release actuation, it ensures that once triggered, the device cannot be reset without using the key, preventing unintended restarts. It is engineered for panel mounting through a standard 22 mm diameter cutout, making it compatible with various control systems.

The push button is equipped with a SPDT (Single Pole Double Throw) contact configuration offering one normally open and one normally closed switching contact. This supports control circuits with a contact current rating of 2A and an AC voltage rating of up to 300V. Installation is made straightforward with screw-type terminals providing secure and maintenance-friendly electrical connections.

Constructed from lightweight yet chemically resistant polyester and plastic materials, the housing and push button ensure long service life even in challenging environments. The device holds multiple ingress protection certifications - IP20, IP66, IP67, and IP69K - verifying its capability to withstand dust ingress and water jets, including high-pressure washdowns often found in food processing or pharmaceutical industries.

Safety is further enhanced with three-pole safety contacts segregating signalling paths for increased reliability in safety circuits. The emergency stop button complies with IECEx for hazardous areas and adheres to recognized safety standards including ISO13850 and EN60947 series, guaranteeing certified and reliable performance in critical industrial applications.

Typical use cases include emergency shutdowns of automated production lines, interlock circuits in packaging machinery, control panels in hazardous atmospheres, and retrofit safety upgrades in electrical cabinetry. The product is supplied with a key release mechanism and includes two keys for controlled reset operations.

Features key release actuation to prevent accidental reset after activation. Designed with a 22 mm cutout and mushroom-style red head for rapid manual actuation. Provides SPDT contact configuration supporting 2A current at up to 300V AC.

Offers high ingress protection ratings IP20, IP66, IP67, and IP69K for dust-tight and washdown usage. Equipped with screw terminal connectors ensuring reliable electrical contact. Includes three-pole safety contacts for separated safety signalling paths.

Meets IECEx hazardous area certification for use in explosive atmospheres. Conforms to ISO13850 and EN60947 series standards for emergency stop functionality. Constructed with polyester housing and plastic push button material for chemical resistance and durability.
