Circuit breaker ETI ETIMAT 10 3P 125A C 15kA (2135733)

ETIMAT 10 by ETI is a circuit breaker designed to protect electrical circuits against overload and short-circuit currents in AC networks. With three poles, it is intended for use in three-phase distribution lines where switching and protection of power circuits are required in industrial, commercial, and engineering electrical installations. The device is rated for a current of 125 A and uses a C tripping characteristic. This trip curve is suitable for circuits with moderate inrush currents, helping to avoid nuisance tripping when connected loads briefly draw a higher current during start-up. The breaking capacity of 15 kA is an important parameter for distribution boards and power lines, as it indicates the breaker’s ability to interrupt high fault currents under short-circuit conditions. The breaker operates in AC circuits with a rated voltage of 415 V and a frequency of 50/60 Hz. These values define its intended use in standard low-voltage three-phase systems. The rated impulse withstand voltage Uimp of 4 kV reflects resistance to short-duration voltage surges that may occur in the electrical network. The device supports conductor cross-sections from 25 to 50 mm², which makes it suitable for connection in power circuits with appropriately sized cables. This model complies with IEC/EN 60947-2, the standard for low-voltage switchgear and controlgear, confirming that it is designed in line with established requirements for protective and switching devices. In practice, ETIMAT 10 3P 125A C 15kA is used in main or group feeders where a compact modular solution is needed for installation in a distribution panel and reliable protection of three-phase consumers. Its combination of three-pole construction, high rated current, strong breaking capacity, and standard-compliant design makes it appropriate for organized protection of power circuits in a wide range of electrical installations.
