Product information

Description

The Siemens SIRIUS surge suppressor diode assembly is designed for reliable integration with size S00 contactors and auxiliary contactors in industrial automation systems. This electrical component effectively limits voltage spikes caused by switching operations, protecting sensitive control circuits and extending the operational lifespan of connected equipment.

Advantages

The Siemens surge suppressor offers dependable protection against high induction voltages generated during contactor coil de-energization. Engineered as part of the flexible SIRIUS modular system, it integrates seamlessly without requiring extra mounting space. Its robust electrical design ensures stable performance across standard industrial voltage ranges, minimizing electromagnetic interference and contributing to overall system reliability.

Suitable for

  • Protection of Siemens SIRIUS size S00 contactors
  • Safeguarding auxiliary contactors in control panels
  • Industrial automation and motor control applications
  • Electrical installations operating on AC and DC control supplies

When it may not be suitable

This surge suppressor is not compatible with contactor sizes other than S00, such as S0, S2, or S3. It is also unsuitable for control supply voltages that fall outside the specified 127-240V AC and 150-250V DC operational ranges.

Key specifications

  • Compatible with size S00 contactors (3RT2.1) and auxiliary contactors (3RH2)
  • Control supply voltage: 127-240V AC (50/60 Hz) and 150-250V DC
  • Device type: Diode assembly surge suppressor
  • Package dimensions: 31 mm width, 56 mm depth, 10 mm height

How to use

Installation should be performed by qualified personnel in accordance with standard electrical safety procedures. Ensure the control circuit is completely de-energized before mounting the accessory. The diode assembly is plugged directly into the designated interface on the compatible size S00 contactor or auxiliary contactor, ensuring correct polarity and secure mechanical seating prior to system startup.

What to consider before purchase

  • Verify the exact contactor series and size to ensure compatibility with size S00 components
  • Check the control circuit voltage to match the 127-240V AC or 150-250V DC rating
  • Confirm available physical space within the control cabinet or panel

Usage recommendations

Always disconnect power to the control panel before installing or servicing electrical accessories, and periodically inspect connections to ensure continuous surge protection and reliable system operation.
