Product information

Description

The Siemens SITOR F 3NC1091 Cylindrical Fuse Switch Disconnector 1-Pole 32A 690V AC IP20 is a dependable electrical protection device engineered for industrial environments and power distribution systems. This 1-pole switch disconnector operates at a rated current of up to 32A and a voltage of 690V AC, providing reliable switching and overcurrent protection for electrical installations. Designed to accommodate 10x38mm SITOR semiconductor fuses, the unit ensures effective safeguarding of equipment and systems through safe circuit shutdown during overloads or short-circuits. With its IP20 protection rating, the device is suitable for integration into standardized switchgear setups, offering robust performance and operational safety.

Advantages

The Siemens SITOR F switch disconnector delivers exceptional protection capabilities thanks to its super-fast switch-off characteristics and high characteristic curve fidelity. These features allow the device to reliably protect sensitive power semiconductors far more effectively than conventional NH fuses. As an essential component of the SENTRON protection product family, it guarantees secure operation, helping to prevent equipment damage and ensuring overall system reliability in demanding electrical applications.

Suitable for

  • Industrial switchgear assemblies
  • Power distribution systems
  • Protection of power semiconductors
  • Electrical installations requiring overload and short-circuit protection

When it may not be suitable

This device is not designed for outdoor use or in environments exposed to moisture and dust without a proper protective enclosure, as it features an IP20 rating. It is also unsuitable for electrical circuits exceeding 32A or 690V AC, and it should not be applied outside of compatible SITOR fuse link dimensions.

Key specifications

  • 1-pole configuration
  • Rated current up to 32 A
  • Rated voltage of 690 V AC
  • Compatible with 10x38mm fuse links
  • IP20 ingress protection rating

How to use

Installation should be performed by qualified electrical personnel in accordance with relevant safety standards and local regulations. The device is mounted onto standard switchgear structures where it houses a compatible 10x38mm SITOR fuse. Ensure all power is disconnected before installing or replacing the fuse element. Operate the switch handle manually to open or close the circuit as required during maintenance or routine operation.

What to consider before purchase

  • Verify that the current rating of 32A and voltage of 690V AC match your specific electrical system requirements
  • Ensure compatibility with 10x38mm SITOR semiconductor fuses
  • Check that the IP20 protection rating meets the environmental conditions of your enclosure
  • Confirm that the installation space within your switchgear assembly is sufficient

Usage recommendations: Always use compatible SITOR semiconductor fuses rated correctly for your application. Regularly inspect the switch disconnector and connections for signs of wear or damage, and ensure that maintenance is only performed by trained professionals with the power supply completely isolated.

Design

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
