ETI ETIMAT P10 Automatic Circuit Breaker 3P 50A B 10kA (1901315)

The ETI ETIMAT P10 automatic circuit breaker is designed to protect electrical circuits against overload and short circuit conditions. It is intended for installation in distribution boards of residential, commercial, and small industrial facilities where reliable switching and protection of three-phase lines or consumer groups is required. This model has 3 poles and a rated current of 50 A, which makes it suitable for circuits with the corresponding load level. The B tripping characteristic provides fast disconnection when the current exceeds the permissible value, so the device is typically used in circuits with low inrush currents. Such a characteristic is often selected for standard distribution networks, where protection must react quickly to fault currents without unnecessary delay. The breaking capacity of 10 kA is an important parameter for safely interrupting short-circuit current at the declared level. This allows the circuit breaker to operate in networks where higher fault currents may occur and helps protect both the wiring and connected equipment. The device is designed for AC circuits with a rated voltage of 415 V and a frequency of 50/60 Hz, which confirms its suitability for use in common three-phase power systems. Another technical feature is the rated impulse withstand voltage Uimp of 6 kV. This indicates resistance to short-term overvoltage events caused by switching operations or external disturbances in the electrical network. In practical terms, it increases the appliance’s ability to remain stable under transient electrical stress. The device supports conductor cross-sections from 1 mm² to 25 mm², which simplifies selection during installation and makes it easier to integrate into different panel configurations. Compliance with EN/IEC 60898 confirms conformity with the requirements for circuit breakers used in household and similar electrical installations. ETIMAT P10 3P 50A B 10kA is a modular circuit breaker for protecting three-phase circuits where rated current, breaking capacity, and B-curve tripping are key selection criteria.
