ETI ETIMAT 10 is an automatic circuit breaker designed to protect AC electrical circuits against overloads and short circuits. The 3P+N configuration makes it suitable for three-phase lines with a neutral conductor, where the three phase conductors and the neutral need to be used together in the same distribution circuit. Such devices are typically installed in distribution boards for residential, commercial, and small industrial applications. This model is rated for a nominal current of 40 A and uses a C tripping characteristic. That means it is intended for circuits with moderate inrush currents, such as lines supplying equipment that may draw a higher current briefly during startup. The breaking capacity of 10 kA allows the breaker to disconnect the circuit under high short-circuit currents, helping to protect the wiring and connected equipment in the event of a fault. The device is designed for AC systems with a nominal voltage of 400 V and a frequency of 50/60 Hz, which makes it compatible with standard three-phase networks. The nominal impulse withstand voltage Uimp is 6 kV, indicating resistance to short-term voltage surges that can occur in electrical installations. The connection range of 1–25 mm² supports common conductor cross-sections used in panel wiring and distribution systems. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its suitability for modular electrical switchboard applications. With clearly defined switching parameters, 3P+N pole arrangement, and a 40 A / C / 10 kA specification, this breaker is a practical choice for organizing circuit protection in systems where separation of phase and neutral conductors is required.
