2173303 Диф. автоматичний вимикач KZS-2M B 13/0,3 тип AC (10kA)

The ETI KZS-2M differential automatic circuit breaker is designed to protect electrical circuits against overload, short circuit, and residual current. It is used in distribution boards of residential, commercial, and small industrial facilities where combined protection and automatic disconnection of a line are required. The 1+N pole design makes the device suitable for single-phase networks with a neutral conductor, providing protection of the phase conductor and switching of the neutral conductor according to the connection diagram. The rated current of 13 A makes this device appropriate for circuits with moderate load. The residual current rating of 0.3 A is intended for installations where protection against leakage currents in wiring and connected equipment is required. The B tripping characteristic indicates suitability for lines with low inrush currents, which is typical for lighting and general socket circuits. Type AC means the device responds to alternating residual current, so it is intended for circuits with this type of load behavior. The breaking capacity of 10 kA allows the breaker to be used in networks with elevated short-circuit current levels, expanding its application in modern electrical distribution systems. The rated frequency of 50/60 Hz ensures compatibility with both common AC network frequencies. The permissible conductor cross-section of 1 to 25 mm² simplifies cable selection for a specific wiring scheme and installation conditions. The device complies with IEC/EN 61009, the standard governing residual current operated circuit breakers with overcurrent protection. This standard confirms that the product is intended for combined protection of individual lines, helping to organize circuit protection in a compact and practical form within the electrical panel. The KZS-2M series is therefore suitable for use where overload protection, short-circuit protection, and residual current monitoring must be implemented in a single modular device.
