ETI ETIMAT 6 Circuit Breaker 3P 50A C 6kA (2145521)

This ETI ETIMAT 6 automatic circuit breaker is designed to protect electrical circuits against overload and short-circuit currents. It is intended for installation in distribution boards used in residential, commercial, and industrial facilities where reliable switching and protection of three-phase lines are required. The three-pole design allows simultaneous disconnection of three conductors, which is suitable for 400 V AC networks. The device is rated at 50 A, making it appropriate for circuits with higher load demand. The C tripping characteristic is used in lines with moderate inrush currents, such as supply circuits for equipment with electric motors, transformers, and other loads that briefly draw current above the operating level. This characteristic helps the breaker respond correctly to both overload and fault conditions without unnecessary tripping in typical applications. With a breaking capacity of 6 kA, the breaker can interrupt short-circuit currents up to the declared value, which is an important parameter for standard low-voltage installations. The rated AC voltage is 400 V, and the operating frequency range is 50/60 Hz, so the device can be used in common power systems with either frequency. The rated impulse withstand voltage Uimp of 6 kV indicates resistance to short-term voltage surges that may occur during switching operations or due to external disturbances in the electrical network. The breaker accepts conductors with a cross-section from 1 to 25 mm², which simplifies integration into a variety of wiring schemes. It complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming conformity with the technical requirements applied to low-voltage circuit breakers. As a result, the ETIMAT 6 series model combines a 3-pole configuration, 50 A rating, C curve, and 6 kA breaking capacity for use in protected three-phase circuits.
