Description

Overview

The Siemens 5SY4206-7 is a premium 2-pole miniature circuit breaker designed for superior circuit protection. Rated at 6 A with a C curve tripping characteristic, it ensures fast and reliable response to overcurrents, safeguarding electrical systems efficiently. With a 400V operating voltage and 10kA short-circuit breaking capacity, this compact 70mm device is perfect for residential, commercial, and industrial applications.

Key Features

  • Rated Voltage: 400V AC

  • Current Rating: 6 A

  • Poles: 2

  • Tripping Curve: C curve (ideal for general protection and inductive loads)

  • Breaking Capacity: 10kA

  • Width (D): 70 mm, compact for modular panels

  • Reliable Protection: Protects circuits against overloads and short circuits

  • Durable Construction: Long-lasting performance for industrial and residential use

Function

The primary function of the 5SY4206-7 MCB is to protect cables and lines against overload and short circuit faults.

  1. Overload Protection (Thermal Principle): A sustained current slightly above 6 A heats a bimetallic strip, which eventually trips the mechanism.

  2. Short-Circuit Protection (Electromagnetic Principle): A sudden, large current (short circuit) generates a strong magnetic field that instantly trips the mechanism, providing immediate isolation.

Benefit

  • Superior Safety: High 10 kA short-circuit breaking capacity provides robust protection for industrial power distribution.

  • Reliable Performance: Siemens quality guarantees long-term operational integrity and reduced maintenance costs.

  • Space-Saving Design: The compact 2-pole design and optimized 70 mm depth allow for efficient use of space within distribution boards and control panels.

  • Quick Installation: Features user-friendly terminal connections for fast and secure mounting on a standard DIN rail.
