5SV3342-4 SIEMENS

The 5SV3342-4 is a four-pole residual current circuit breaker (RCCB) meticulously engineered by Siemens to provide comprehensive protection against electrical faults. This RCCB is designed to detect residual currents, which indicate insulation failures or earth faults, and promptly interrupt the circuit to prevent electrical shocks and fire hazards. Featuring a Type B tripping characteristic, it is suitable for circuits with sensitive electronic equipment. The short-time delayed tripping mechanism ensures selectivity in cascaded RCCB systems, preventing nuisance tripping due to transient fault currents. With a rated current (In) of 25A, this RCCB can handle moderate electrical loads in residential, commercial, and industrial applications. Its sensitivity to residual currents is set at 30mA, providing a high level of protection against potentially lethal electric shocks. The RCCB is designed for a rated AC voltage (Un AC) of 400V, making it compatible with standard three-phase power systems. This device enhances electrical safety by quickly disconnecting the power supply upon detection of dangerous leakage currents. Siemens' commitment to quality and reliability ensures that the 5SV3342-4 RCCB delivers dependable performance and long-lasting protection. It is an essential component for modern electrical installations, safeguarding people and property from the risks associated with electrical faults.
