5SV3644-4 SIEMENS

The 5SV3644-4 is a four-pole residual current operated 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, offering enhanced protection against nuisance tripping caused by transient currents. The 5SV3644-4 incorporates a short-time delayed tripping mechanism, allowing for discrimination in selective protection schemes and preventing unwanted tripping due to temporary fault currents. With a rated current (In) of 40 A, this RCCB is capable of handling substantial electrical loads in industrial and commercial applications. Its rated residual current (IΔn) of 300 mA ensures reliable detection of earth leakage currents, providing an additional layer of safety. The RCCB is designed for a rated AC voltage (Un AC) of 400 V, making it compatible with standard three-phase power systems. This device is essential for ensuring electrical safety in a wide range of applications, including industrial facilities, commercial buildings, and residential installations. The 5SV3644-4 offers a robust and dependable solution for protecting people and equipment from the dangers of electrical faults. Its advanced features and high-quality construction make it a valuable component in any electrical protection system.
