SIEMENS
High-performance Universal Current Circuit Breaker designed for both AC and DC applications. Featuring a 10A rated current and a 2-pole configuration, this C-characteristic MCB provides reliable protection with a 10kA breaking capacity, making it ideal for demanding industrial environments.
The Siemens 5SY5210-7 belongs to the premium 5SY5 series, engineered for versatility and safety. This Miniature Circuit Breaker (MCB) is uniquely designed to handle universal current, allowing it to function seamlessly in 440 V DC systems and 400 V AC networks.
Whether you are protecting sensitive industrial controls or renewable energy infrastructure, the 5SY5210-7 offers the precision of a C-type tripping characteristic, which is perfect for circuits with moderate peak starting currents.
Dual Current Compatibility: Optimized for both Alternating Current (AC) and Direct Current (DC) applications.
Enhanced Safety: The 10kA breaking capacity ensures robust protection against short circuits and overloads.
Space-Saving Design: The 2-pole construction provides comprehensive circuit interruption in a compact form factor.
Industrial Durability: Built to Siemens’ rigorous quality standards for long-term operational reliability.
Overload Protection: Thermal tripping element for sustained overcurrent conditions.
Short-Circuit Protection: Electromagnetic tripping for instantaneous response to faults.
Universal Application: Specifically designed for DC voltages up to 440 V, common in battery systems and solar PV applications.
