ABB 1SFA Series Key Release Emergency Stop Push Button Panel Mount 22.5 mm Cutout SPDT 300V 1SFA619552R1071 - CE4K1-10R-11

ABB 1SFA619552R1071 - CE4K1-10R-11 Emergency Stop Push Button is a high-reliability panel-mounted safety device designed for rapid manual shutdown in industrial control and automation systems. It features a large 40 mm mushroom head diameter colored red for clear visibility and easy actuation in critical emergency scenarios. The unit mounts in a standard 22.5 mm panel cutout and uses a key release actuation mechanism to prevent unauthorized or accidental reactivation after an emergency stop.

The product is constructed with a durable polyester housing that offers excellent chemical resistance, making it suitable for harsh industrial environments. Its IP20, IP66, IP67, and IP69K ratings ensure dust-tight sealing and protection against water ingress, including high-pressure and high-temperature washdowns, making it ideal for wet or washdown areas.

Electrical switching is handled by 1 normally open (NO) and 1 normally closed (NC) contacts arranged as SPDT, rated for control circuits up to 300 volts AC and 2 amps current. Connections are made via secure screw terminals, which allow reliable field wiring and serviceability. The inclusion of two auxiliary contacts provides enhanced safety monitoring options, enabling integration with redundant circuits or status relays.

Certification includes IECEx for hazardous area suitability, along with compliance to key international safety standards such as ISO13849-1, EN60947-5-1, ISO13850, and EN60947-5-5. This makes the device appropriate for use in environments requiring strict safety protocols, including explosive atmospheres subject to local installation regulations.

Common applications include emergency stop control on conveyor lines, machine tools, packaging machinery, and retrofit safety upgrades in electrical cabinets and hazardous-area production zones. The key release feature requires a removable key to reset after actuation, preventing accidental restarts.
