2172406 Диф. автоматичний вимикач KZS-2M2p EDI B 16/0,03 тип A (10kA) (нижнє підключ.)

ETI KZS-2M2p EDI is a differential automatic circuit breaker designed for combined protection of electrical circuits against overload, short circuit, and leakage currents. It integrates the functions of an automatic circuit breaker and a residual current device in one module, which simplifies distribution board layout and helps save installation space. Such devices are commonly used in residential, commercial, and household switchboards where a compact and functional protection solution is required. The device has 2 poles, so it is intended for single-phase or two-wire circuits where both the phase and neutral conductors need to be controlled simultaneously. The rated current is 16 A, making it suitable for typical lighting and general-purpose household circuits with moderate load levels. The B tripping characteristic indicates operation in circuits with low inrush currents, which is relevant for lighting lines and standard consumer loads. The residual current setting is 0.03 A, providing protection against electric shock and increasing the safety level of the electrical installation. Type A residual current detection allows the device to respond not only to alternating leakage currents but also to pulsating direct leakage currents. This is important in circuits with modern household equipment and electronic loads. The breaking capacity is 10 kA, which means the breaker can operate in networks with elevated short-circuit currents. The rated frequency of 50/60 Hz ensures compatibility with common electrical systems. The nominal conductor cross-section range of 1 mm² to 25 mm² allows connection of conductors of the appropriate size, depending on the design of the circuit and the installation requirements. A separate constructive feature is the bottom connection, which should be taken into account during planning and installation of the switchboard. The device complies with IEC 61009, the standard regulating requirements for differential automatic circuit breakers. This model is intended for organized protection of electrical lines where overcurrent and leakage-current protection are needed in a single device.
