Product information

Description

The Siemens SIRIUS ACT contact block is a professional-grade electrical component designed for seamless integration into industrial control and signaling systems. Engineered for durability and precision, this unit features one normally closed (NC) contact, ensuring reliable circuit interruption when required. It is specifically designed for rear-wall mounting, making it an ideal choice for complex control panels and automation cabinets where space efficiency and secure installation are paramount.

Advantages

This contact block offers exceptional mechanical stability and electrical reliability, which are essential for maintaining continuous operation in demanding industrial environments. Its robust construction ensures long-term performance even under frequent switching cycles. The design facilitates quick and secure installation, allowing for efficient assembly within the SIRIUS ACT modular system. By providing a consistent and stable connection, it helps minimize downtime and enhances the overall safety of electrical control circuits.

Suitable for

  • Industrial automation control panels
  • Emergency stop and safety signaling circuits
  • Machine control interfaces
  • Electrical distribution systems
  • Command and signaling device assemblies

When it may not be suitable

This contact block is not intended for use in high-power switching applications that exceed its rated voltage or current specifications. It is also not suitable for environments requiring specialized ingress protection ratings beyond the standard industrial design, or for applications where a normally open (NO) contact configuration is required instead of the normally closed (NC) type.

Key specifications

  • Contact configuration: 1 NC (Normally Closed)
  • Rated operational voltage: 500 V
  • Mounting type: Rear-wall mounting
  • Compatibility: SIRIUS ACT series

How to use

The contact block is designed to be mounted onto the rear of the command or signaling device holder. Ensure the power supply is disconnected before installation. Align the contact block with the mounting slots on the back of the actuator or holder and press firmly until it clicks into place. Once installed, connect the control wires to the terminals according to your wiring diagram, ensuring all connections are tightened to the specified torque to prevent loose contacts.

What to consider before purchase

  • Verify that your control system requires a normally closed (NC) contact.
  • Ensure the voltage requirements of your circuit do not exceed 500 V.
  • Confirm compatibility with your existing SIRIUS ACT actuator or holder.
  • Check the available space in your control cabinet for rear-wall mounting.

Usage recommendations

Always perform a functional test of the switching circuit after installation to ensure the contact block operates correctly within your control system. Regularly inspect the terminal connections for signs of wear or loosening during scheduled maintenance intervals.
