ETI ETIMAT 10 automatic circuit breaker 3P+N 10A C 10kA (2136714)

ETI ETIMAT 10 is an automatic circuit breaker designed to protect AC electrical circuits against overloads and short circuits. It is used in distribution boards for residential, commercial, and industrial installations where several phase conductors and the neutral must be controlled together. The 3P+N configuration means three poles plus neutral, making the device suitable for three-phase circuits with single-phase or mixed loads. The breaker is rated at 10 A, so it is intended for lines with relatively low operating current, such as individual consumer groups, auxiliary circuits, or control lines. The C tripping characteristic indicates suitability for circuits with temporary inrush currents, helping prevent nuisance tripping during equipment start-up. This makes the device appropriate for applications where loads may draw short peak currents at switching on. The breaking capacity is 10 kA, which allows the breaker to interrupt high fault currents in the event of a short circuit. This parameter is important for installations with elevated prospective short-circuit currents and provides the required level of circuit protection in typical modern networks. The device is designed for AC systems with a rated voltage of 400 V and a rated frequency of 50/60 Hz. It also has a rated impulse withstand voltage of 6 kV, confirming its resistance to short-duration overvoltages in the electrical system. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define the requirements for low-voltage protective switching devices. The permissible conductor cross-section for connection is 1–25 mm², allowing integration into standard switchboard assemblies with a wide range of conductor sizes. In practice, this simplifies installation in modular panels and helps adapt the breaker to different wiring arrangements. With its 3P+N pole arrangement, 10 A rating, C curve, and 10 kA breaking capacity, this ETI circuit breaker is intended for reliable protection of three-phase circuits where both functional separation and neutral switching are required.
