Product Information

Full details

This Siemens 3SU1400-1AA10-1CA0 auxiliary contact block is designed for industrial control and signaling applications, offering reliable electrical flow control for electricians and control system engineers. Its primary benefit is the robust construction and wide voltage/current ratings for demanding environments. A key consideration is its specific function as a normally closed (NC) contact, which may require integration into a broader control circuit design. Key features include a 5-500V AC/DC voltage range, 10A current rating, and screw terminals for secure connections.

FAQs

What does '1 NC' mean for this contact block?

'1 NC' signifies that the contact block has one Normally Closed (NC) contact. This means the electrical circuit is closed (conducting) when the contact block is de-energized and opens (stops conducting) when the actuator is pressed or the associated switch is activated.

Can I use this contact block with AC and DC power supplies?

Yes, this Siemens contact block is rated for both AC and DC power supplies, operating reliably within a voltage range of 5V to 500V AC/DC.

What is the maximum current this contact block can handle?

The maximum current rating for this contact block is 10A. It is suitable for heavy-duty industrial applications within this limit.

Does this contact block come with an LED indicator?

No, the Siemens 3SU1400-1AA10-1CA0 model does not include an integrated LED indicator.

How is this contact block mounted?

It utilizes a snap-on mounting concept from the SIRIUS ACT series, allowing for tool-free, one-handed installation onto compatible actuators or mounting bases. It also features integrated anti-twist protection.

Is this product suitable for outdoor use?

Yes, the SIRIUS ACT devices, including this contact block, are designed with a high degree of protection making them suitable for industrial use and outdoor applications, resistant to dust, oil, and aggressive chemicals.

What is the 'Better World' claim associated with this product?

The 'Better World' claim refers to its extended product life and low carbon manufacturing processes, indicating a focus on sustainability.

Troubleshooting

Contact block not functioning (not breaking circuit when energized)

Verify that the control voltage is within the 5-500V AC/DC range and that the wiring to the screw terminals is secure and correct for an NC configuration.

Difficulty mounting the contact block

Ensure you are using compatible SIRIUS ACT components and that the mounting holes on the panel or actuator are correctly prepared. Check for obstructions in the snap-fit mechanism.

Overheating or poor contact

Confirm the load current does not exceed the 10A rating. Check for loose terminal connections. Ensure the environment is within acceptable operating temperature limits and free from excessive dust or contaminants.

Pros and Cons

Pros

  • Versatile voltage and current ratings suitable for many industrial tasks.
  • Robust build quality ensures longevity in harsh environments.
  • Simple and secure snap-on mounting mechanism.
  • Part of a well-established and reliable Siemens product line.
  • High degree of protection against environmental factors.

Cons

  • Only provides a single NC contact; may require multiple units for complex switching.
  • No integrated LED indicator.
  • Requires separate mounting onto a base or device; not a standalone switch.
  • Minimum order quantity might apply for bulk purchases.

Setup, Compatibility & Care

Setup: The Siemens 3SU1400-1AA10-1CA0 is designed for easy installation within the SIRIUS ACT system. It utilizes an innovative snap-on concept that requires only one hand and no special tools. The contact block attaches to a compatible base or actuator. Ensure the mounting holes are prepared; slot-free holes are sufficient due to integrated anti-twist protection.

Compatibility: This contact block is part of the Siemens SIRIUS ACT series. It is compatible with other SIRIUS ACT components such as pushbuttons, selector switches, and indicator lights. While designed for panel mounting, it can also be integrated with controllers via PROFINET, AS-Interface, or IO-Link if the main device supports these communication protocols.

Care: To maintain optimal performance and longevity, clean the contact block with a dry or slightly damp cloth. Avoid using harsh solvents or abrasive materials that could damage the plastic housing or internal components. Ensure connections remain tight and free from corrosion. In industrial environments, regular inspection for dust accumulation or physical damage is recommended. High-pressure cleaning is permissible, but ensure all seals are intact and connections are protected.
