Circuit breaker ETI ETIMAT 6 3P+N C 3A 6kA (2146509)

The ETI ETIMAT 6 automatic circuit breaker is intended for protecting electrical circuits against overload and short circuit in AC networks. It is designed in a 3P+N configuration, which means three phases are switched together with the neutral conductor. This makes the device suitable for three-phase systems where coordinated control of all active conductors is required, especially in distribution boards used in residential, commercial, and industrial installations. With a rated current of 3 A, the breaker is used in circuits with relatively low operating load, where accurate protection of the line is needed. The C tripping characteristic allows the device to operate properly in circuits with moderate inrush currents, such as those where short-term current peaks may appear during equipment start-up. This makes the unit suitable for protecting lines with connected loads that may briefly draw higher current at switching on. The breaking capacity is 6 kA, which enables the breaker to disconnect fault currents of short circuit within the range typical for low-voltage distribution systems. The device is rated for 400 V AC and a frequency of 50/60 Hz, so it corresponds to standard parameters of three-phase mains. The impulse withstand voltage Uimp is 6 kV, indicating resistance to switching and impulse overvoltages within the specified limits. The terminal arrangement supports conductor cross-sections from 1 mm² to 25 mm², which simplifies integration into different wiring schemes and allows connection of conductors commonly used in switchboard assemblies. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its suitability for use in electrical installations that require circuit protection according to recognized technical requirements. ETIMAT 6 is a modular protective device for installation in distribution boards on DIN-rail systems. It is used where a three-phase supply with neutral must be protected and disconnected in a controlled manner, while maintaining defined electrical parameters and standardized protection against overload and short circuit.
