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