ETI KZS-2M2p EDI differential circuit breaker C 16 A 30 mA type A 10 kA, bottom connection (2172416)

ETI KZS-2M2p EDI is a differential circuit breaker designed for protecting electrical lines against overload, short circuit, and leakage currents. It is used in distribution boards of residential, commercial, and utility electrical installations where one device must combine overcurrent protection and residual current protection in a single modular unit. This model has 2 poles and a rated current of 16 A, which makes it suitable for individual single-phase circuits with moderate load. The C tripping characteristic allows use in circuits with higher inrush currents, such as lighting groups, socket circuits, and separate loads with electric motors or electronic power supplies. The rated residual current is 0.03 A, or 30 mA, which is a widely used protection level for reducing the risk of electric shock and disconnecting the circuit when dangerous leakage current appears. The device has Type A residual current sensitivity. This means it responds to alternating sinusoidal residual current and pulsating direct residual current, so it can be used in circuits with household appliances and electronic loads. The breaking capacity is 10 kA, which is suitable for networks with increased short-circuit current levels and provides the ability to disconnect fault currents within the specified limits. The nominal frequency is 50/60 Hz, allowing application in systems with either standard frequency. The permitted conductor cross-section is 1 to 25 mm², which should be considered during wiring and installation in the distribution board. Bottom connection simplifies conductor arrangement inside the panel and can make modular layout more convenient during assembly. The product complies with IEC 61009, the standard governing differential circuit breakers. This makes the device appropriate for projects where technical compliance, defined operating parameters, and compact installation are required. Due to the combination of an automatic circuit breaker function and residual current protection, the unit is a practical choice for local protection of separate electrical groups in modern low-voltage installations.
