5SV4344-0MB SIEMENS

The 5SV4344-0MB is a four-pole residual current circuit breaker (RCCB) designed and manufactured by Siemens. This RCCB is engineered to provide reliable protection against electrical shocks and fire hazards in residential, commercial, and industrial applications. It is a Type AC RCCB, which means it is designed to detect alternating current (AC) residual currents. The device has a rated current (In) of 40A, indicating the maximum current it can continuously carry without tripping. Its sensitivity is 30mA, meaning it will trip when a residual current of 30mA or higher is detected, quickly interrupting the circuit to prevent harm. The rated voltage (Un) is 400V AC, making it suitable for standard three-phase power systems. The 5SV4344-0MB RCCB offers dependable protection against earth faults and leakage currents, enhancing electrical safety. It is essential for safeguarding people and equipment from the dangers of electrical faults. This device is easy to install and compatible with standard DIN rails, ensuring seamless integration into existing electrical panels. Siemens is known for its high-quality and reliable electrical protection devices, and the 5SV4344-0MB is no exception.
