2173121 Диф. автоматичний вимикач KZS-2M C 6/0,03 тип AC (10kA)

ETI KZS-2M is a differential circuit breaker designed to protect electrical circuits against overload, short circuit, and leakage current. By combining the functions of an automatic circuit breaker and a residual current protective device, it is used in distribution boards of residential, commercial, and other electrical installations where both overcurrent and differential protection are required in a single device. The device is rated for a nominal current of 6 A, which makes it suitable for protecting low-power lines. Tripping characteristic C indicates suitability for circuits with moderate inrush currents, such as lines supplying devices that may draw a short старт-up surge. The rated residual operating current of 0.03 A provides disconnection when dangerous leakage current appears, helping improve electrical safety in typical AC networks. Type AC means the device responds to sinusoidal alternating residual current. This model has a 1+N pole configuration, so it switches the phase conductor together with the neutral. The breaking capacity of 10 kA allows use in networks where higher short-circuit currents may occur. The nominal frequency is 50/60 Hz, which makes the device compatible with common AC supply systems. ETI KZS-2M complies with IEC/EN 61009, the standard governing differential circuit breakers. The permissible conductor cross-section is 1–25 mm², which should be considered when selecting cables and preparing terminal connections during installation. With these parameters, the device can be used in group circuits and individual lines where compact protection against overload, short circuit, and leakage current is required.
