Description
Overview
The Siemens 5SY6304-7 belongs to the premier SENTRON series of protection devices. Specifically engineered for industrial and commercial applications, this MCB ensures maximum safety and system availability. With a compact mounting depth of 70 mm, it integrates seamlessly into standard distribution boards and control cabinets.
Key Benefit
-
Enhanced Safety: Provides superior protection for cables and systems against thermal overload and short-circuit faults.
-
Reliable Performance: The C-tripping characteristic is ideal for circuits with higher inrush currents, such as motors and lighting groups.
-
Compact Design: The 70 mm installation depth saves valuable space in electrical enclosures.
-
Global Standards: Fully compliant with international safety standards for industrial use.
Function
-
Short-Circuit Protection: Immediate disconnection in the event of a high-current fault (6kA capacity).
-
Overload Protection: Delayed tripping to prevent damage from sustained over-current.
-
Manual Switching: Ergonomic handle allows for easy manual isolation of the circuit for maintenance.
