Automatic circuit breaker ETI ETIMAT P10 1P 40A C 10kA (1901034)

The ETI ETIMAT P10 series automatic circuit breaker is intended for protection of electrical circuits against overload and short circuit in residential, commercial, and other low-voltage installations. It is used in distribution boards where automatic disconnection of a line is required under abnormal operating conditions. The 1-pole design makes it suitable for protecting a single phase conductor in AC single-phase circuits. This model is rated at 40 A, so it is selected for circuits with an appropriate load current. The C tripping characteristic means the device is suitable for lines with moderate inrush currents, for example circuits feeding equipment that can briefly draw a higher current at start-up. The breaking capacity of 10 kA indicates the breaker’s ability to interrupt short-circuit currents within the specified limit, which is an important parameter for safeguarding the electrical installation and connected equipment. The breaker is designed for AC networks with a nominal voltage of 240 V and a frequency of 50/60 Hz. The rated impulse withstand voltage Uimp of 6 kV reflects resistance to short-duration voltage surges. The permissible conductor cross-section range of 1–25 mm² allows connection of wires and cables within the stated limits, which simplifies integration into electrical distribution circuits. The device complies with EN/IEC 60898, the standard for modular circuit breakers intended for household and similar applications. ETIMAT P10 combines a 1-pole configuration, 40 A rated current, C curve, and 10 kA breaking capacity, making it a practical protective element for group and distribution circuits in AC power systems.
