Circuit breaker ETI ETIMAT P10 3P+N 1A D 10kA (1901442)

The ETI ETIMAT P10 is an automatic circuit breaker intended for protection of AC electrical circuits against overload and short circuit. Its 3P+N configuration means it is designed for three-phase networks with a neutral conductor, providing simultaneous switching of the phase conductors while also including the neutral path in the circuit arrangement. This makes the device suitable for distribution boards in residential, commercial, and technical electrical installations where coordinated protection of a four-wire line is required. With a rated current of 1 A, the breaker is intended for circuits with low load or for lines that require precise current protection. The D tripping characteristic indicates a higher tolerance to inrush currents, which is important for loads that draw a significant start-up current at switch-on. For this reason, the device can be used in applications where temporary current peaks should not trigger unnecessary tripping. The breaking capacity of 10 kA provides protection during high short-circuit currents, which is an important parameter for electrical networks with elevated fault-current requirements. The breaker is designed for AC operation at a nominal voltage of 415 V and a frequency of 50/60 Hz. Its rated impulse withstand voltage Uimp is 6 kV, which reflects resistance to transient overvoltages in the power system. These parameters make the model suitable for integration into low-voltage distribution systems operating under standard mains conditions. The device is installed in a modular electrical panel, following the common layout used for protective and switching devices on DIN-rail based assemblies. Another practical advantage is the connection range for conductors from 1 mm² to 25 mm². This allows the breaker to be used with different wiring cross-sections, provided they remain within the specified limits. The product complies with EN/IEC 60898, confirming its intended use as a protective apparatus for low-voltage household and similar installations. Overall, the ETIMAT P10 3P+N 1 A D 10 kA model is a functional choice for protecting three-phase circuits with neutral in systems where compact modular installation and defined short-circuit protection parameters are required.
