2172417 Диф. автоматичний вимикач KZS-2M2p EDI C 20/0,03 тип A (10kA) (нижнє підключ.)

The ETI KZS-2M2p EDI differential circuit breaker is intended for combined protection of electrical circuits against overload, short circuit, and leakage currents. It is used in distribution boards for residential, commercial, and small industrial facilities where the functions of an automatic circuit breaker and a residual current device are combined in one unit. The lower connection arrangement simplifies wiring in the panel and helps organize conductor entry in the required direction. This model has 2 poles and a rated current of 20 A. The C tripping characteristic makes it suitable for circuits with moderate inrush currents, such as lines supplying equipment that may briefly draw higher current at start-up. The rated residual current of 0.03 A, or 30 mA, provides protection against dangerous leakage currents and is commonly used for group circuits where additional personal protection against electric shock is required. The breaking capacity is 10 kA, which allows the device to operate in networks with increased short-circuit current levels. This makes it appropriate for circuits where higher fault current values may occur. The device is designed for a rated frequency of 50/60 Hz, so it can be used in electrical systems operating at either standard frequency. The permissible conductor cross-section is 1 to 25 mm², which should be considered during panel design and cable termination. The device complies with IEC 61009, the standard governing residual current operated circuit-breakers with integral overcurrent protection. Type A indicates compatibility with alternating residual currents and pulsating direct residual currents, which is important for modern electrical loads. Thanks to the combination of overcurrent protection and leakage current protection, this breaker is suitable for separate socket, lighting, and other feeder circuits where compact protection equipment is required in the distribution board.
