Description

Overview

The Siemens 5SY4150-7 Miniature Circuit Breaker is a top-of-the-line electrical protection device designed to safeguard circuits from overloads and short circuits. With a high breaking capacity of 10kA, this single-pole circuit breaker is rated for use in 230/400V electrical systems. Featuring a 50A current rating and a C curve, it is ideal for general-purpose protection in residential and commercial applications.

Benefit

  • Reliable Protection: Provides superior protection against overloads and short circuits for residential, industrial, and commercial applications.

  • High Breaking Capacity: Withstands fault currents of up to 10kA, ensuring safety in demanding environments.

  • Compact Design: Only 70mm in depth, allowing for efficient space-saving installation in electrical panels.

  • C Curve Rating: Designed to trip between 5 to 10 times the rated current, providing balanced protection for most electrical systems.

  • Certified Quality: Manufactured by Siemens, a trusted brand known for high-performance and durable electrical components.

  • Easy Installation: User-friendly design for straightforward mounting on DIN rails, simplifying the installation process.

Functionality

The Siemens 5SY4150-7 is engineered to perform reliably under a wide range of conditions. It features an automatic trip mechanism that activates when current exceeds the preset threshold, protecting circuits and preventing electrical fires, equipment damage, and system failures. Its 50A rating makes it suitable for medium-load applications, and its C curve ensures that the breaker trips in response to moderate overloads.
