Automatic circuit breaker ETI ETIMAT P10 3P+N 20A C 10kA (1901431)

This modular automatic circuit breaker from ETI, belonging to the ETIMAT P10 series, is intended for the protection of AC electrical circuits against overloads and short circuits. With a 3P+N configuration, it is used in three-phase networks with a neutral conductor, making it suitable for distribution boards in residential, commercial, and small industrial installations. The device is designed for mounting in low-voltage switchboards where reliable circuit protection and orderly distribution of electrical lines are required. The rated current of 20 A makes this breaker appropriate for circuits operating under moderate load. Its C tripping characteristic is used for lines with moderate inrush currents, such as circuits supplying equipment that briefly draws a higher current during start-up. This feature helps maintain proper operation without unnecessary tripping in typical loads with transient current peaks. The breaking capacity of 10 kA provides the ability to disconnect the circuit under high short-circuit currents, which is an important parameter for protecting the installation in the event of a fault. The breaker operates in AC systems with a rated voltage of 415 V and a frequency of 50/60 Hz. In addition, the rated impulse withstand voltage Uimp of 6 kV indicates resistance to short-duration voltage surges, which is relevant for electrical networks exposed to switching transients. The product complies with EN/IEC 60898, confirming its intended use in low-voltage distribution systems. The rated conductor cross-section range of 1–25 mm² allows connection of commonly used conductors during panel assembly. Thanks to its modular design, the breaker can be installed on a DIN rail alongside other protective and control devices, which simplifies integration in standard electrical enclosures. ETIMAT P10 3P+N C20 is a practical choice for protecting three-phase lines where correct load distribution, fault interruption, and compliance with standard electrical installation requirements are important.
