## Long description

The Siemens SIRIUS ACT 3SU1400-1AA10-1HA0 is a professional-grade contact module engineered for industrial control systems. This component features a single normally closed (NC) contact, providing reliable switching performance for various automation and safety applications. Designed for seamless integration within the SIRIUS ACT series, this module ensures robust connectivity and long-term operational stability in demanding industrial environments.
Advantages
This contact module stands out due to its high mechanical and electrical durability, which is essential for maintaining consistent performance in intensive industrial settings. The use of high-quality screw terminals facilitates a secure and vibration-resistant electrical connection, minimizing the risk of signal loss or maintenance requirements. Its compact design allows for efficient space utilization within control panels, while the standardized interface ensures compatibility with a wide range of SIRIUS ACT actuators and mounting components.
Suitable for
Industrial control panels and automation systems
Emergency stop circuits requiring NC contact configuration
Machine control interfaces
Safety-critical switching applications
When it may not be suitable
This module is not intended for applications requiring multiple contact points or normally open (NO) switching logic, as it is strictly configured with a single NC contact. It is also not suitable for environments exceeding the specified environmental protection ratings or electrical load capacities defined by the manufacturer.
Key specifications
Contact configuration: 1 NC (Normally Closed)
Connection type: Screw terminals
Series: SIRIUS ACT
Application: Industrial control and switching
How to use
The module is designed for front-plate mounting and can be easily snapped into the corresponding SIRIUS ACT holder. To install, ensure the power supply is disconnected. Insert the module into the holder until it clicks into place. Connect the electrical wires to the screw terminals, ensuring they are tightened to the recommended torque to guarantee a secure connection. After installation, verify the switching function by testing the actuator before putting the system into full operation.
What to consider before purchase
Verify that your control system requires a normally closed (NC) contact configuration.
Ensure the screw terminal connection is compatible with your existing wiring standards.
Check that the module is compatible with your specific SIRIUS ACT actuator or mounting bracket.
Usage recommendations
Always ensure that the electrical load connected to the contact module does not exceed the rated operational current and voltage specifications to prevent premature wear or failure of the internal contacts.
