5SV3344-4 SIEMENS

The 5SV3344-4 is a four-pole residual current circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This RCCB is 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 B tripping characteristic, it is suitable for circuits with sensitive electronic equipment, offering enhanced immunity to nuisance tripping caused by transient currents. The device has a rated current (In) of 40A, making it suitable for medium-sized electrical installations. With a sensitivity of 30mA, it ensures a high level of protection against indirect contact hazards. The 5SV3344-4 is designed for a rated voltage (Un AC) of 400V, commonly used in three-phase electrical systems. Its short-time delayed tripping characteristic provides discrimination in cascaded RCCB systems, preventing unwanted tripping of upstream devices. This RCCB is essential for ensuring electrical safety in residential, commercial, and industrial applications. It adheres to stringent quality standards, guaranteeing reliable performance and long service life. The Siemens 5SV3344-4 RCCB offers a dependable solution for safeguarding people and equipment from electrical hazards.
