ETI ETIMAT P10 automatic circuit breaker 1P 3A B 10kA (1901005)

The ETI ETIMAT P10 is a single-pole automatic circuit breaker designed to protect electrical circuits against overloads and short circuits. It is suitable for use in distribution boards in residential, commercial, and light industrial installations where one individual line must be protected with defined electrical parameters. With one pole, the device is intended for single-phase circuits and separate supply lines, making it applicable for lighting circuits, auxiliary loads, and other low-power single-phase consumers. The rated current is 3 A, so the breaker is intended for circuits with a relatively small current load. Its B tripping characteristic means it responds quickly in circuits with low inrush currents, which is especially important where a more sensitive disconnection is required in the event of a fault. This characteristic is commonly used for lines without significant starting surges. The breaking capacity of 10 kA indicates the ability to interrupt high short-circuit currents, which is an important parameter for installations with elevated protection requirements. The device is designed for AC systems with a rated voltage of 240 V and a frequency of 50/60 Hz. The rated impulse withstand voltage Uimp is 6 kV, which reflects resistance to transient overvoltages in the network. Such a parameter is relevant for maintaining protective performance under electrical disturbances in the supply line. Connection of conductors is possible in the range from 1 mm² to 25 mm², which provides compatibility with a wide selection of cable and wire cross-sections used in standard electrical installation work. The breaker complies with EN/IEC 60898, the standard for circuit breakers intended for household and similar applications. This makes it appropriate for modular switchboards where a compact protective device is needed for a dedicated circuit with fixed operating parameters.
