2173327 Диф. автоматичний вимикач KZS-2M C 32/0,3 тип AC (10kA)

ETI KZS-2M is a differential automatic circuit breaker designed to protect electrical circuits against overload, short circuit, and residual current faults. It is used in distribution boards for residential, commercial, and other electrical installations where combined protection of overcurrent and earth-leakage conditions is required in one device. The 1+N pole configuration makes it suitable for single-phase circuits with a neutral conductor, which is typical for lighting groups, socket circuits, and separate connected loads. The device is rated at 32 A and has a C tripping characteristic. This characteristic is intended for circuits with moderate inrush currents, making the breaker appropriate for loads that may draw short-term starting currents during operation. The rated residual current is 0.3 A, so the unit monitors leakage currents and disconnects the line when insulation is damaged or current flows to exposed conductive parts. Type AC indicates use in circuits where the residual current has a sinusoidal alternating waveform. With a breaking capacity of 10 kA, the breaker is capable of interrupting circuits under significant short-circuit currents, which is important in networks with elevated fault current levels. The rated frequency of 50/60 Hz allows use in installations operating at either of these standard mains frequencies. The device supports conductor cross-sections from 1 to 25 mm², which simplifies installation and makes it compatible with a wide range of cable sizes within the specified limits. The product complies with IEC/EN 61009, the standard for differential automatic circuit breakers. This confirms its application as a combined protective device for one circuit in switchboard assemblies, where protection against overload, short circuit, and leakage current must be provided in a compact module.
