Product information

Description

The Hager ST303N miniature circuit breaker is a reliable electrical component designed to ensure electrical safety and effective circuit protection in various distribution systems. Engineered with precision, this device helps safeguard your electrical installations against potential overloads and short circuits, maintaining stable operation in residential and commercial environments.

Advantages

This miniature circuit breaker provides dependable protection for electrical circuits by interrupting the flow of current when a fault is detected. Its robust construction ensures long-term durability and consistent performance. The compact two-module design allows for efficient space utilization within distribution boards, while the standard 230 V rating makes it fully compatible with common electrical setups.

Suitable for

  • Residential electrical distribution systems
  • Commercial building sub-panels
  • Preventing electrical overloads and short circuits
  • Standard 230 V electrical installations

When it may not be suitable

This device is not designed for environments requiring high water or dust resistance due to its IP20 rating. Additionally, it is not suitable for applications that exceed its specified voltage and module capacity parameters.

Key specifications

  • Rated voltage: 230 V
  • Module capacity: 2 modules
  • Protection rating: IP20
  • Brand: Hager

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. Mount the device securely onto a standard DIN rail within a compatible enclosure or distribution board. Ensure all wiring connections are properly tightened before restoring power to the circuit.

What to consider before purchase

  • Verify that the 230 V rating matches your electrical system requirements
  • Check available space in your distribution board for a 2-module device
  • Confirm that an IP20 protection rating is suitable for your installation environment
  • Ensure installation is planned with the assistance of a certified professional
Usage recommendations: Regularly inspect the installation for any signs of wear or loose connections. Test the functionality periodically as part of routine electrical maintenance to ensure continuous protection.

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".
