This circuit breaker from the ETIMAT 10 series by ETI is designed to protect AC electrical circuits against overloads and short circuits. The 3P+N configuration makes it suitable for four-wire three-phase lines, where three phase conductors and the neutral conductor must be controlled together. It is commonly used in distribution boards of residential, commercial, and industrial installations for protecting feeder lines, group circuits, and loads with higher inrush currents. The device is rated at 40 A, which allows it to be applied in circuits with a corresponding operating load. The D tripping characteristic indicates that the breaker is intended for circuits with high starting currents, such as motor-driven equipment, transformers, and other loads that may briefly draw current above the nominal value. This makes the device appropriate for installations where temporary current surges are expected during startup. The breaking capacity of 10 kA provides disconnection under high short-circuit currents, which is important in networks with increased fault current levels. The breaker is designed for 400 V AC systems at 50/60 Hz. Its rated impulse withstand voltage, Uimp, is 6 kV, indicating resistance to transient overvoltages in the electrical network. The permitted conductor cross-section is 1 to 25 mm², which simplifies installation and allows connection of conductors within the specified technical range. The model complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its suitability for distribution systems and line protection tasks. ETIMAT 10 is a modular device for mounting in electrical distribution panels where reliable protection of three-phase circuits with neutral and operation under AC network conditions are required.
