Circuit breaker ETI ETIMAT 10 3P 20A C 10 kA (2135717)

ETIMAT 10 by ETI is a three-pole circuit breaker designed for protection of electrical circuits against overload and short circuit. It is intended for installation in distribution boards of residential, commercial, and industrial facilities where branch circuits require switching and protection under moderate operating load. The three poles allow simultaneous disconnection of three conductors, which is relevant for AC networks with a nominal voltage of 400 V. With a rated current of 20 A, the device can be used in supply circuits for equipment, socket groups, and other consumers that require this level of current protection. The C tripping characteristic indicates suitability for circuits with increased inrush currents, where short-term current peaks may occur during switching on of electrical loads. This makes the breaker applicable in installations with appliances that have starting currents higher than the steady-state operating current. The breaking capacity of 10 kA means the breaker is capable of interrupting high short-circuit currents, which expands its use in networks with a higher expected fault level. The nominal impulse withstand voltage Uimp is 6 kV, characterizing the device’s ability to withstand transient overvoltage events in the electrical system. The breaker is designed for AC operation at a frequency of 50/60 Hz, matching common power distribution conditions. The permitted conductor cross-section range is 1 to 25 mm², which simplifies integration into standard internal wiring schemes and distribution assemblies. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2, standards that define requirements for modular circuit breakers and their protective performance. These technical parameters make the device a suitable solution for organizing protection and control of three-phase lines in switchboards where a 20 A rating, C characteristic, and 10 kA breaking capacity are required.
