Automatic circuit breaker ETI ETIMAT P10 3P+N D 16A 10kA (1901450)

ETI ETIMAT P10 is an automatic circuit breaker intended for protecting electrical circuits against overload and short circuit in AC networks. The 3P+N design makes it suitable for four-wire three-phase systems where three phase conductors and the neutral must be switched together. This configuration is commonly used in distribution boards of residential, commercial, and small industrial installations, where coordinated protection of group and power circuits is required. The device is rated at 16 A, which defines its application in circuits with corresponding load levels. The D tripping characteristic indicates suitability for circuits with elevated inrush currents, such as those supplying electric motors, transformers, and other equipment that briefly draws a significantly higher current at start-up. With a breaking capacity of 10 kA, the breaker is designed to interrupt fault currents at a high short-circuit level, which is an important parameter for electrical systems exposed to more demanding operating conditions. The breaker is designed for AC voltage and operates at a rated voltage of 415 V AC with a nominal frequency of 50/60 Hz. This makes it compatible with widely used three-phase AC networks. The rated impulse withstand voltage, Uimp, of 6 kV reflects resistance to impulse overvoltages within the limits expected for this class of modular protective equipment. Such electrical characteristics allow the device to be used in installations where stable circuit disconnection and protection are required under normal and fault conditions. For conductor connection, the breaker supports a nominal cross-section range from 1 mm² to 25 mm², which provides flexibility when used with different cable types and wiring arrangements. The product complies with EN/IEC 60898, the standard governing automatic circuit breakers for household and similar installations. Overall, the ETIMAT P10 series breaker is a practical solution for distribution panels that require simultaneous switching of phase conductors and neutral, along with dependable protection against overload and short-circuit events.
