Automatic circuit breaker ETI ETIMAT 10 3P D 32A 10 kA (2155719)

ETIMAT 10 from ETI is an automatic circuit breaker designed to protect electrical circuits against overloads and short circuits in AC networks. With three poles, it is intended for three-phase lines where simultaneous disconnection of all phases is required. This configuration is commonly used in distribution boards for residential, commercial, and industrial applications, especially where a single device must monitor and disconnect a multi-phase circuit. The rated current of 32 A makes the device suitable for circuits with moderate load. The D tripping characteristic indicates use in circuits with higher inrush currents, where short-term current peaks occur during start-up. For this reason, the breaker can be applied in circuits supplying electric motors, transformers, and other loads with pronounced starting currents. The breaking capacity of 10 kA provides protection when interrupting fault currents of significant magnitude, which is an important parameter for networks with elevated short-circuit requirements. The device is rated for AC operation at 400 V and 50/60 Hz. The rated impulse withstand voltage Uimp is 6 kV, showing resistance to short-duration overvoltages in the electrical system. Connection of conductors is supported within a cross-section range from 1 to 25 mm², which facilitates integration into different wiring schemes and simplifies installation in distribution equipment. The breaker complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define the technical and operational requirements for low-voltage circuit breakers. These standards confirm that the device is designed for use in protective switching applications in low-voltage installations. As a three-pole 32 A breaker with D curve and 10 kA breaking capacity, this model is a practical solution for protecting three-phase electrical circuits where both reliable overload protection and short-circuit interruption are required.
