ETI ETIMAT P10 Miniature Circuit Breaker 1P 0.5A C 10kA (1901021)

This miniature circuit breaker from the ETIMAT P10 series by ETI is intended for protection of electrical circuits against overload and short circuit. It is used in distribution boards of residential, commercial, and technical facilities where individual line protection and controlled disconnection under fault conditions are required. The 1-pole design makes it suitable for single-phase AC circuits. The device is rated at 0.5 A and features a C tripping characteristic. This means it is suitable for circuits with short-term inrush currents while still ensuring disconnection in the event of overload or short-circuit current. The 10 kA breaking capacity provides the ability to interrupt fault currents of significant magnitude, which is important in networks with elevated protection requirements. The breaker operates in AC circuits with a rated voltage of 240 V and a frequency of 50/60 Hz. The rated impulse withstand voltage Uimp is 6 kV, indicating resistance to impulse overvoltages in the electrical network. The permitted conductor cross-section is 1–25 mm², which allows connection of conductors within the specified range and supports use in different wiring configurations. Compliance with EN/IEC 60898 confirms that the device meets the requirements for miniature circuit breakers used in household and similar installations. With its combination of 1P execution, C characteristic, 0.5 A rating, and 10 kA breaking capacity, this model is designed for protection of low-power lines where precise current protection and stable operation in modular switchgear are needed.
