2173224 Диф. автоматичний вимикач KZS-2M C 16/0,03 тип A (10kA)

ETI KZS-2M is a differential circuit breaker designed to protect electrical lines against overload, short circuit, and residual current faults. It is used in distribution boards for residential, commercial, and general building electrical systems where combined protection in one modular device is required. By integrating the functions of an automatic circuit breaker and a residual current device, it helps reduce the number of separate modules in the panel and simplifies circuit protection arrangement. The device has a 1+N pole configuration, meaning one protected pole and one neutral conductor. The rated current is 16 A, which makes it suitable for circuits with moderate load. The C tripping characteristic is intended for lines with increased inrush currents, such as circuits supplying equipment with electric motors or other devices that draw a higher start-up current. The rated residual operating current is 0.03 A, so the breaker responds to dangerous leakage currents and supports additional protection of people and equipment. A breaking capacity of 10 kA allows the device to operate in networks where high short-circuit currents may occur. This parameter is important for panels installed in systems with higher fault current levels, as it defines the ability of the breaker to disconnect the circuit under severe fault conditions. The device is designed for operation at 50/60 Hz, which expands its applicability within the limits specified by the standard. The product complies with IEC/EN 61009, confirming that it belongs to the class of differential circuit breakers. The rated conductor cross-section is 1–25 mm², which should be considered when selecting conductors for the protected line and planning the wiring in the distribution board. This range supports practical connection of typical cables used in modular switchboards. Overall, the KZS-2M series device is intended for local protection of individual circuits and grouped loads where overcurrent protection and residual current protection must work together in one unit. It is a functional solution for panel-based installations in apartments, houses, offices, and other low- and medium-complexity electrical systems.
