5SV3344-3 SIEMENS

The 5SV3344-3 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This RCCB is specifically designed to detect residual currents, which are indicative of insulation failures or earth faults, and promptly interrupt the circuit to prevent electrical shocks and fire hazards. Featuring a Type F classification, the 5SV3344-3 is particularly sensitive to mixed frequency currents and DC residual currents, offering enhanced protection in modern electrical systems with electronic devices. The short-time delayed tripping characteristic ensures selectivity in cascaded installations, preventing nuisance tripping due to transient faults while maintaining reliable protection against persistent faults. With a rated current (In) of 40 A and a tripping current (30 mA), this RCCB is suitable for a wide range of applications in commercial and industrial settings. It is designed for an AC voltage (Un AC) of 400 V, making it compatible with standard European power grids. The 5SV3344-3 RCCB provides a crucial layer of safety, protecting people and equipment from the dangers of electrical faults. Its robust design and compliance with international standards ensure reliable performance and long service life. This device is an essential component for any electrical installation prioritizing safety and continuity of service.
