5SV3746-5 SIEMENS

The 5SV3746-5 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 indicate insulation failures or earth faults, and promptly interrupts 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 selective tripping characteristic ensures that only the faulty circuit is disconnected, minimizing disruption to other parts of the electrical system. With a rated current (In) of 63A, this RCCB can handle substantial loads in industrial and commercial applications. Its residual current rating (IΔn) of 500mA provides a balance between sensitivity and immunity to leakage currents. The device is designed for a rated voltage (Un) of 400V AC, making it compatible with standard three-phase power systems. Siemens' 5SV3746-5 RCCB combines reliability, precision, and safety to deliver superior protection for electrical installations. It is an ideal choice for applications where continuity of service and protection against electrical hazards are paramount. This RCCB adheres to stringent quality standards, ensuring long-lasting performance and peace of mind.
