ETI ETIMAT 10 circuit breaker 3P 50A B 6kA (2125721)

The ETIMAT 10 circuit breaker from ETI is designed to protect electrical circuits against overload and short circuit in low-voltage distribution systems. It is suitable for installation in distribution boards of residential, commercial, and small industrial facilities where reliable switching and protection of three-phase lines are required. With three poles, the device disconnects all phases simultaneously, which supports safe operation of AC networks and helps prevent uneven disconnection of the protected circuit. This model is rated for a current of 50 A and operates in AC systems with a rated voltage of 400 V. The B tripping characteristic means the device is intended for circuits with low inrush currents, making it appropriate for lighting circuits, socket groups, and other loads that do not require increased tolerance to starting surges. The breaking capacity of 6 kA allows the circuit breaker to interrupt fault currents within the limits commonly expected in domestic and most commercial installations. The unit also features a rated impulse withstand voltage Uimp of 6 kV, which indicates resistance to short-duration voltage surges in the electrical network. Its rated frequency of 50/60 Hz makes it compatible with widely used supply standards. The acceptable conductor cross-section range of 1 to 25 mm² provides flexibility when connecting conductors of the specified size, including installation within standard distribution assemblies. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2, standards that define requirements for low-voltage modular circuit breakers and protective switching devices. These standards confirm its intended use in electrical protection applications and help ensure conformity with common installation practices. Overall, this three-pole 50 A breaker with B curve and 6 kA breaking capacity is a suitable component for protecting and isolating three-phase lines where compact modular protection is needed.
