5SV3646-6KL SIEMENS

The 5SV3646-6KL is a 4-pole residual current operated circuit breaker (RCCB) designed and manufactured by Siemens. This RCCB provides comprehensive protection against residual currents, also known as earth leakage currents, ensuring electrical safety in various applications. It is a Type A RCCB, which means it is sensitive to both AC and pulsating DC residual currents. The rated current (In) of this device is 63A, indicating its capacity to handle continuous currents up to 63 amperes. The sensitivity to residual currents is 300mA, meaning it will trip and interrupt the circuit when a residual current of 300 milliamperes or higher is detected. It is designed for a rated voltage (Un AC) of 400V, suitable for standard three-phase power systems. The 'N left' designation indicates the position of the neutral conductor connection on the left side of the device. This RCCB is crucial for preventing electrical shocks and fire hazards caused by insulation faults or other electrical anomalies. It is commonly used in residential, commercial, and industrial settings to protect people and equipment from dangerous electrical conditions. Siemens is a trusted brand known for its high-quality and reliable electrical protection devices.
