ETI ETIMAT 6 miniature circuit breaker 3P C 3A 6kA (2145509)

The ETIMAT 6 miniature circuit breaker by ETI is intended for protection of electrical circuits against overloads and short circuits in AC networks. It is used in distribution boards in residential, administrative, and commercial facilities where automatic disconnection of a line is required under fault conditions. With three poles, the device is suitable for three-phase circuits or for group protection of lines that require three-pole switching. The rated current is 3 A, so this circuit breaker is designed for circuits with a low load. The C tripping characteristic means it can operate properly in circuits with moderate inrush currents, which is important for lines supplying equipment with a short-term increase in current at start-up. The breaking capacity of 6 kA indicates the maximum short-circuit current the device can interrupt within its specified operating conditions. This model is rated for 400 V AC and a frequency of 50/60 Hz, which matches typical low-voltage electrical systems. The rated impulse withstand voltage Uimp of 6 kV shows resistance to transient overvoltages in the network. The accepted conductor cross-section range of 1 mm² to 25 mm² allows use with different wiring configurations, provided the cable is selected according to the installation requirements. The device complies with IEC/EN 60898-1 and IEC 60947-2, standards that define the requirements for low-voltage circuit breakers. This makes the model suitable for projects where technical conformity and standardized parameters are important. ETIMAT 6 is a practical solution for protecting individual electrical lines in switchgear assemblies and for use in systems where a compact modular protective device is required.
