Description

Overview

The Siemens 5SJ4106-8HG42 is part of the Sentron series, specifically engineered for the North American market while maintaining global standards. This miniature circuit breaker (MCB) provides reliable protection against overloads and short circuits. Its Type D tripping characteristic is specifically designed for circuits with high inrush currents, such as transformers, motors, and high-intensity lighting.

Key Benefit

  • Global Compliance: Meets UL 489 and CSA C22.2 No. 5-02 standards, making it suitable for branch circuit protection in North America.

  • Enhanced Safety: Provides a 10kA interrupting rating to prevent equipment damage during high-fault current events.

  • Space Efficient: The compact 1-pole design (18mm width) allows for maximum density within electrical panels.

  • Durability: Built with Siemens' world-class engineering to ensure a long mechanical and electrical lifespan.

Function

  • Short-Circuit Protection: Instantaneous tripping in the event of a high-current fault.

  • Overload Protection: Thermal tripping mechanism to protect wiring from sustained overcurrent.

  • Branch Circuit Protection: Approved for use as a primary protector in electrical distribution systems.
