The Siemens 5SY4104-7 is a high-quality miniature circuit breaker designed to provide overcurrent protection in a variety of applications. This 1-pole breaker is engineered for use in both commercial and industrial settings, ensuring safety and reliability in electrical circuits. With a tripping characteristic class of C, it is suitable for protecting installations with a higher inrush current, such as motors and transformers.
Rated for 230/400 V AC, this circuit breaker is capable of interrupting short-circuit currents up to 10kA, offering robust protection against electrical faults. Its compact design, with a depth of 70 mm, allows for efficient use of space within electrical distribution boards. The 5SY4104-7 is part of the SENTRON product family, known for its durability and ease of use.
The mechanical service life of this device is typically 20,000 switching cycles, indicating a long-lasting performance. It is classified under overvoltage category III, which means it is designed to handle transient overvoltages typically found in fixed installation environments. The insulation voltage ratings are 250 V for single-phase and 440 V for multi-phase operations, providing a safe and effective barrier against electrical surges.
This miniature circuit breaker is a reliable choice for those seeking a dependable solution to protect electrical circuits from overloads and short circuits, ensuring the safety and efficiency of electrical systems in a range of settings.
