ETI ETIMAT 10 Circuit breaker 3P+N 1.6A C 10kA (2136707)

The ETIMAT 10 circuit breaker by ETI is designed for protecting AC electrical circuits against overloads and short circuits. It is intended for use in distribution boards in residential, commercial, and small industrial installations where reliable switching and line protection are required. The 3P+N pole configuration makes it suitable for four-wire networks, as it disconnects three phase conductors and the neutral conductor in a coordinated manner. With a rated current of 1.6 A, this device is suitable for low-power consumers or individual lines with limited load. The C tripping characteristic indicates suitability for circuits with moderate inrush currents, which is relevant for applications where short-term current peaks may occur during equipment startup. The breaking capacity of 10 kA allows the breaker to interrupt high fault currents, which is an important parameter for systems with an increased short-circuit level. The breaker is designed for AC networks with a rated voltage of 400 V and a rated frequency of 50/60 Hz, making it compatible with standard alternating-current installations. The rated impulse withstand voltage Uimp of 6 kV characterizes its resistance to transient overvoltages within the limits expected for this class of modular protective devices. The permissible conductor cross-section range of 1–25 mm² facilitates integration with different cable and wiring configurations during installation. This model complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define the requirements for circuit breakers, their electrical characteristics, and operating parameters. In practice, the device is used where compact modular protection is needed in a DIN-rail mounted enclosure. Its configuration and technical ratings make it appropriate for building electrical systems in which both functional switching and protective disconnection of circuits are essential.
