SIEMENS
High-performance Miniature Circuit Breaker (MCB) designed for superior electrical circuit protection. Featuring a 3-pole configuration, 63A current rating, and Type C tripping characteristic, it provides reliable defense against overloads and short circuits in industrial and commercial environments.
The Siemens 5SY6363-7 belongs to the renowned Sentron series, offering a compact and robust solution for electrical distribution. With a mounting depth of 70 mm and a breaking capacity of 6kA, this MCB is engineered for durability and ease of installation in standard distribution boards. It is specifically designed to handle moderate inrush currents typical of motor and lighting circuits.
Overload Protection: Safely interrupts power during sustained over-current conditions.
Short-Circuit Protection: Instantaneous tripping in the event of a fault to prevent equipment damage.
Manual Switching: Allows for safe manual disconnection of the circuit for maintenance.
Reliable Performance: Siemens engineering ensures long-term operational stability and safety compliance.
Space-Saving Design: The 70 mm depth allows for standardized installation in space-constrained panels.
Versatile Application: The Type C characteristic is ideal for circuits with higher inductive loads.
Enhanced Safety: Clearly visible contact position indicators for operator safety.
Automatically disconnects circuits during overload or fault conditions
Protects electrical equipment from damage
Ensures system stability and operational safety
Supports safe power distribution in industrial and commercial installations
