ETI ETIMAT 10 circuit breaker 3P 20A B 10kA (2125717)

The ETI ETIMAT 10 is a three-pole circuit breaker designed for protection of electrical circuits against overload and short-circuit currents. It is intended for installation in distribution boards of residential, administrative, and commercial facilities where separate protection of supply lines in AC networks is required. By switching all three phases simultaneously, the device is suitable for three-phase loads and grouped circuits with corresponding connection requirements. This breaker has a rated current of 20 A, which places it in the range for circuits with moderate load. The B tripping characteristic means it responds quickly to fault currents and is intended for circuits with low inrush currents, such as lighting lines and other branches without significant startup loads. The breaking capacity of 10 kA allows the device to disconnect high short-circuit currents in networks where strong fault currents may occur, increasing its suitability for common distribution applications. The circuit breaker is rated for 400 V AC and a frequency of 50/60 Hz, making it compatible with standard three-phase alternating current systems. Its impulse withstand voltage Uimp of 6 kV indicates resistance to short-duration voltage surges in the electrical network. The permissible conductor cross-section of 1 to 25 mm² supports connection of widely used cable and wire sizes and simplifies installation in switchgear assemblies. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2, confirming its conformity to recognized standards for low-voltage protective switching devices. As a modular protective device, it is mounted in distribution boards alongside other modular equipment and is used to organize selective protection of individual lines. The combination of 3 poles, 20 A rating, B characteristic, and 10 kA breaking capacity makes this model suitable for circuit protection where reliable disconnection and clear coordination with the network parameters are required.
