Automatic circuit breaker ETI ETIMAT 10 3P+N 100A C 20kA (2136732)

The ETI ETIMAT 10 automatic circuit breaker is intended for protection and switching of AC electrical circuits against overload and short circuit. It is suitable for use in three-phase four-wire systems, where simultaneous switching of three phases and the neutral conductor is required. This makes the device applicable in distribution boards for residential, commercial, and industrial installations with higher load levels. The device has a rated current of 100 A, which allows it to be used in power circuits with significant current demand. Tripping characteristic C indicates suitability for lines with moderate inrush currents, including circuits feeding electrical equipment that may draw a short-term surge at startup. The breaking capacity of 20 kA provides a high level of protection during short-circuit events, which is especially important in networks with elevated prospective fault current. The breaker is rated for AC 415 V and operates at 50/60 Hz. The rated impulse withstand voltage Uimp is 4 kV, which confirms its ability to withstand short-duration overvoltages that may occur during switching operations or external disturbances in the electrical network. The terminal range of 25–50 mm² supports connection of conductors used in high-current supply lines and distribution circuits. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define the technical requirements, safety parameters, and operating characteristics of automatic circuit breakers. This combination of specifications makes the model a practical solution for protection and control of power circuits where a three-phase configuration, high breaking capacity, and standardized performance are required.
