Differential circuit breaker ETI KZS-2M 2P 6A 0.03A B type AC 10kA (2173101)

The ETI KZS-2M differential circuit breaker is designed to protect electrical circuits against overload, short circuit, and residual current. It combines the functions of an automatic overcurrent protection device and a residual current protective device in a single housing, making it suitable for distribution boards in residential, administrative, and small commercial installations where compact circuit protection is required. This model is rated at 6 A and features a B tripping characteristic, which is intended for circuits with low inrush currents. The residual current sensitivity is 0.03 A, or 30 mA, so the device reacts to leakage currents that may indicate insulation faults or hazardous contact conditions. The 1+N pole configuration means one protected pole plus neutral, which is commonly used in single-phase branch circuits. With a breaking capacity of 10 kA, the unit can be used in networks where high short-circuit currents may occur. The breaker is designed for operation in 50/60 Hz electrical systems. Its connection range is 1 to 25 mm², allowing it to accommodate conductors within the specified cross-section limits. Compliance with IEC/EN 61009 confirms that the device corresponds to the requirements for differential circuit breakers and provides the relevant protection functions within the defined standard. ETI KZS-2M is appropriate for lighting circuits, socket circuits, and other individual loads that require both overcurrent and residual current protection. By integrating these functions into one modular device, it helps simplify panel layout and reduce the number of separate protective modules needed in the switchboard.
