Description

Overview

The Siemens 3SU1400-2AA10-1CA0 is a crucial component within the SIRIUS ACT system of commanding and signaling devices. This is a configurable contact block, specifically a Contact Module with 1 Contact Element (1NC), designed to provide a reliable switching function for auxiliary and control circuits. Its silver alloy contacts guarantee high contact reliability and a long mechanical service life of 10 million operating cycles. The robust screw terminal connection ensures secure and easy wiring in challenging industrial environments.

Key Features & Function

The 3SU1400-2AA10-1CA0 contact module translates the mechanical action of a pushbutton, selector switch, or EMERGENCY STOP actuator into an electrical signal. As an NC (Normally Closed) contact, it allows current to flow in its idle state. When the coupled actuator is pressed (or turned), the module is mechanically triggered, causing the NC contact to open and interrupt the circuit. This is the standard configuration for functions like machine stop, where the circuit must be broken to ensure safety.

Benefit

  • Ensures safe and reliable operation of industrial equipment.

  • Facilitates easy and secure installation.

  • Compatible with a wide range of Siemens automation systems.

  • Reduces maintenance downtime thanks to robust build quality.

Application

This contact module is an essential component for control panels, machinery, and industrial automation systems where reliable signaling is required:

  • Safety Circuits: Used as the NC contact for EMERGENCY STOP pushbuttons to ensure positive opening.

  • Control Desks and Panels: Integration with SIRIUS ACT pushbuttons, selector switches, and indicator lights.

  • Machine Tools: Auxiliary switching in control devices for start/stop functions.

  • Process Control: Reliable signal transmission in complex automation processes.
