2172401 Диф. автоматичний вимикач KZS-2M2p EDI B 6/0,03 тип A (10kA) (нижнє підключ.)

ETI KZS-2M2p EDI is a differential circuit breaker designed to protect electrical lines against overload, short circuit, and leakage current. It combines the functions of a miniature circuit breaker and a residual current protective device in one unit, which makes it suitable for distribution boards in residential, administrative, and commercial facilities. The lower connection arrangement simplifies wiring in the panel and can be convenient when conductors are brought in from the corresponding side. This device has 2 poles and a rated current of 6 A, so it is intended for the protection of individual single-phase circuits with relatively low load, such as lighting or auxiliary lines. The B tripping characteristic means the device responds promptly in circuits without significant inrush currents. The breaking capacity of 10 kA allows it to disconnect fault currents in networks with the corresponding short-circuit level. The rated residual current is 0.03 A, or 30 mA, which helps detect dangerous leakage currents and improves electrical safety for people and equipment. Type A indicates compatibility not only with sinusoidal alternating residual currents, but also with pulsating direct residual components that may appear in modern electronic loads. This makes the unit suitable for circuits where appliances with electronic power supplies are used. The rated frequency is 50/60 Hz, so the device can operate in networks with either of these standard frequencies. The permissible conductor cross-section is 1 to 25 mm², which provides flexibility during installation and connection in distribution equipment. Compliance with IEC 61009 confirms that the product belongs to the category of differential circuit breakers and meets the relevant functional and test requirements. In practice, this model is used for localized protection of individual circuits where both overcurrent protection and leakage-current protection are required in a compact modular format. Its technical characteristics make it appropriate for panel installations where correct coordination of rated current, sensitivity, tripping curve, and breaking capacity is important.
