ETI ETIMAT 6 3-pole 0.5A D curve 6kA circuit breaker (2164501)

This ETI ETIMAT 6 automatic circuit breaker is designed for protection of AC electrical circuits against overload and short circuit. It is intended for installation in distribution boards used in residential, commercial, and industrial applications where three-wire or three-phase circuits require simultaneous disconnection of all active lines. The 3-pole design makes it suitable for switching and protecting multi-phase feeders, helping maintain correct operation of the electrical installation. The device has a rated current of 0.5 A, which makes it appropriate for circuits with very low load and for protecting sensitive electrical equipment that requires precise overcurrent protection. The D tripping characteristic allows the breaker to tolerate higher short-duration inrush currents, which is useful in circuits where transient startup currents may occur. At the same time, it still provides protection against dangerous fault conditions such as overload and short circuit. With a breaking capacity of 6 kA, the breaker is able to interrupt short-circuit currents typical for many standard power distribution systems. It is designed for AC networks with a rated voltage of 400 V and a rated frequency of 50/60 Hz. The nominal impulse withstand voltage Uimp is 6 kV, indicating resistance to impulse overvoltage levels expected for this class of equipment. Connection is possible with conductors in the 1 to 25 mm² cross-section range, which supports use in common panel wiring arrangements. The breaker complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its suitability for circuit protection and distribution applications in electrical panels. Overall, this model combines 3-pole switching, D curve tripping, 0.5 A rating, and 6 kA breaking capacity for precise protection of low-current AC circuits.
