Availability: In stock
Overview
The Siemens 3SU1400-1AA10-3DA0 belongs to the renowned SIRIUS ACT series, a modular system of pushbuttons and signaling devices. This specific contact module is engineered for users who require a fast, maintenance-free installation. With its dual contact elements, it provides redundant or multi-circuit control in a compact form factor.
Key Benefit
-
Time-Saving Installation: The spring-type terminal technology allows for quick wiring without the need for specialized tools, reducing labor costs.
-
Vibration Proof: Unlike screw terminals, spring terminals maintain a constant pressure, making them ideal for high-vibration machinery.
-
Modular Flexibility: Easily snaps into the SIRIUS ACT holder for front-plate mounting, allowing for custom control configurations.
-
Long Service Life: Built with Siemens’ industrial-grade materials to ensure high electrical and mechanical endurance.
Function & Application
This contact module functions as the electrical switching heart of a pushbutton or selector switch. When the actuator is pressed, the 2 NO contacts close to complete the circuits.
-
Emergency Stop Stations: For signaling and control logic.
-
Control Panels: Integrated into industrial dashboards for motor starting or process control.
-
Machine Building: Used in CNC machines, conveyors, and assembly lines.
