2173424 Диф. автоматичний вимикач KZS-2M C 16/0,3 тип A (10kA)

The ETI KZS-2M differential circuit breaker is designed to protect electrical lines against overloads, short circuits, and leakage currents. It is used in distribution boards for residential, commercial, and auxiliary electrical networks where compact combined protection is required in a single device. By integrating the functions of an automatic overcurrent breaker and residual-current protection, it helps simplify the layout of single-phase circuits. This model is built in a 1P+N configuration, meaning it has one protected pole and a neutral conductor. The rated current is 16 A, which makes the device suitable for individual lighting circuits, socket groups, and other single-phase loads within this current rating. The C tripping characteristic indicates suitability for circuits with moderate inrush currents, such as lines feeding equipment with brief startup peaks. The type A residual-current function ensures operation in the presence of alternating and pulsating direct leakage currents, which is important for many modern household and commercial loads. The rated residual current is 0.3 A, providing protection against leakage currents at this threshold. The breaking capacity of 10 kA allows the device to be used in installations where higher prospective short-circuit currents may occur. This parameter is especially relevant for electrical systems connected to stronger supply networks or protected distribution groups. The operating frequency range of 50/60 Hz ensures compatibility with standard AC power systems. Connection of conductors with a cross-section from 1 to 25 mm² supports installation in typical wiring schemes and makes the device suitable for a wide range of practical applications. Compliance with IEC/EN 61009 confirms that the product meets the requirements applicable to differential circuit breakers. Overall, the KZS-2M series device is intended for situations where it is necessary to combine overload, short-circuit, and leakage current protection in one modular solution for efficient distribution board assembly.
