ETI ETIMAT 10 circuit breaker 3P 80A B 20kA (2125731)

ETIMAT 10 by ETI is an automatic circuit breaker designed to protect AC electrical circuits against overload and short circuit. It is intended for installation in distribution boards used in residential, commercial, and industrial electrical systems, where reliable switching and protection of three-phase lines are required. With a three-pole design, the device enables simultaneous disconnection of all three phases, making it suitable for circuits that need coordinated protection and isolation. The breaker is rated at 80 A, which allows it to be used in circuits with a relatively high operating current. Its B tripping characteristic means it responds to overload and short-circuit conditions in circuits with low inrush current, so it is suitable for loads without pronounced starting surges. This characteristic is typically applied where fast and precise protection is needed for lines with stable current consumption. The breaking capacity of 20 kA provides the ability to interrupt high short-circuit currents, which is an important parameter for protective devices installed in networks with elevated fault current levels. The device is designed for AC systems with a rated voltage of 415 V and a frequency of 50/60 Hz, making it compatible with standard three-phase distribution networks. The rated impulse withstand voltage Uimp is 4 kV, indicating resistance to transient overvoltages that may occur in electrical installations. The permitted conductor cross-section ranges from 1 mm² to 25 mm², which gives flexibility when selecting conductors for different connection schemes and load conditions. The breaker complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its suitability for use in electrical distribution and protection applications. As a modular protective device, it is installed in a distribution board and used to organize safe disconnection of power lines in systems where a 3-pole format, 80 A nominal current, and 20 kA breaking capacity are required.
