2173323 Диф. автоматичний вимикач KZS-2M C 13/0,3 тип AC (10kA)

This ETI KZS-2M differential circuit breaker is designed for protecting electrical lines against overload, short circuit, and leakage currents. It combines the functions of an automatic breaker and a residual current device in one modular unit, making it suitable for distribution boards in residential, commercial, and small industrial installations. The 1+N pole configuration allows connection of the phase conductor and neutral while keeping the device compact and convenient for DIN-rail panel arrangements. The rated current is 13 A, which makes the device appropriate for group circuits with moderate load. The C tripping characteristic is intended for circuits with higher inrush currents, such as supply lines for selected household appliances or electrical equipment that may briefly draw more current during start-up. The rated residual current of 0.3 A provides protection against dangerous leakage currents and is used where differential current monitoring at the 300 mA level is required. This model uses type AC, meaning it responds to sinusoidal alternating residual currents. That makes it suitable for conventional AC electrical networks. The breaking capacity of 10 kA indicates the ability to disconnect the circuit under significant short-circuit currents, which is important for installations with a higher prospective fault current. The rated frequency of 50/60 Hz allows use in networks operating at either of the common mains frequencies. The device complies with IEC/EN 61009, the standard for differential circuit breakers, confirming that its design and operating parameters correspond to the requirements for this category of protective equipment. The permissible conductor cross-section range of 1–25 mm² simplifies cable selection during installation and terminal connection. With its combination of overcurrent and leakage-current protection, this breaker is a practical solution for organizing safe power distribution in electrical systems of different applications.
