5SV3326-4 SIEMENS

The 5SV3326-4 is a 2-pole residual current operated circuit breaker (RCCB) from Siemens, designed to provide enhanced protection against electrical hazards. This RCCB is a Type B device, making it suitable for circuits with sensitive electronic equipment where pulsating DC residual currents may occur. It features a short-time delayed tripping characteristic, which helps to prevent nuisance tripping caused by transient fault currents or surges. With a rated current (In) of 63A, this RCCB can handle substantial electrical loads in residential, commercial, and industrial applications. The sensitivity of 30mA ensures rapid disconnection in the event of a ground fault, minimizing the risk of electric shock. It is designed for a rated voltage (Un AC) of 230V. This RCCB effectively monitors the balance of current between the live and neutral conductors, and quickly interrupts the circuit when an imbalance, indicating a leakage current, is detected. The short-time delay feature allows for discrimination in selective protection schemes. Siemens RCCBs are known for their reliability and contribution to electrical safety.
