ETIMAT P10 from ETI is an automatic circuit breaker designed to protect AC electrical circuits against overload and short circuit. It is used in distribution boards of residential, commercial, and small industrial installations where three-phase line protection is required at a rated voltage of 415 V AC. With three poles, the device allows simultaneous switching and protection of a three-phase circuit, making it suitable for feeder circuits and equipment connected to a three-phase supply. The rated current of 20 A defines its use in circuits with corresponding load levels. The D tripping characteristic indicates suitability for applications with higher inrush currents, such as circuits feeding electric motors, transformers, and other loads that can produce short-term starting surges. This feature helps the breaker withstand momentary current peaks without unnecessary tripping while still providing protection when abnormal current conditions occur. The breaking capacity of 10 kA means the device can interrupt high short-circuit currents, which is important in installations with increased fault current levels. The breaker operates on AC networks at a nominal frequency of 50/60 Hz and has a rated impulse withstand voltage Uimp of 6 kV, reflecting its resistance to short-duration overvoltage events. These parameters are relevant when selecting protection devices for electrical systems that must maintain stable operation under demanding conditions. The product complies with EN/IEC 60898, the standard governing circuit breakers for household and similar installations. This confirms that the device is intended for use in circuit protection schemes where conformity to established electrical requirements is necessary. The permissible conductor cross-section range from 1 to 25 mm² provides flexibility during installation and facilitates integration into different wiring configurations. Combining a three-pole design, 20 A rating, D curve, and 10 kA breaking capacity, this circuit breaker is a practical solution for protecting three-phase lines and connected equipment in installations where startup currents and higher fault levels must be taken into account.
