The ETIMAT 10 series automatic circuit breaker from ETI is designed to protect electrical circuits against overloads and short circuits in distribution boards used in residential, commercial, and industrial installations. Its 3+N configuration means three poles plus neutral, making it suitable for three-phase networks where the neutral conductor must be switched together with the phases. This arrangement is particularly practical for feeder lines and other circuits that require coordinated disconnection of all active conductors. With a rated current of 63 A, the device is intended for circuits with relatively high load demand. The D tripping characteristic makes it appropriate for circuits with elevated inrush currents, such as those supplying electric motors, transformers, and other inductive loads where brief current peaks occur during startup. The breaking capacity of 6 kA defines the breaker’s ability to interrupt fault current within the limits typical for many low-voltage networks, helping isolate a damaged circuit during abnormal operating conditions. The breaker is designed for AC systems with a rated operating voltage of 400 V and a frequency of 50/60 Hz. Its rated impulse withstand voltage Uimp of 6 kV indicates resistance to short-duration voltage surges that may occur during switching events or from external disturbances in the electrical network. These parameters make the device suitable for use in standard low-voltage distribution environments. Connection of conductors is supported across a cross-section range from 1 mm² to 25 mm², which simplifies integration into different wiring schemes and allows compatibility with a wide selection of conductors used in internal electrical installations. Compliance with IEC/EN 60898-1 and IEC 60947-2 confirms that the product meets relevant requirements for low-voltage circuit breakers, including design and testing standards. Overall, this 3+N, 63 A, D-curve breaker with 6 kA breaking capacity is a functional solution for protecting three-phase circuits in distribution systems where controlled switching of the phases and neutral, tolerance to high starting currents, and standardized electrical performance are required.
