Circuit breaker ETI ETIMAT 6 3P+N 40A C 6kA (2146520)

ETIMAT 6 by ETI is a circuit breaker designed to protect electrical circuits against overload and short circuit in AC networks. The 3P+N pole configuration makes it suitable for three-phase circuits with a neutral conductor, where simultaneous switching of the phase lines and neutral is required. This is a practical solution for distribution boards in residential, commercial, and small industrial installations operating at 400 V AC. With a rated current of 40 A, the device can be used for feeder circuits and consumer groups with moderate to increased load. The C tripping characteristic indicates suitability for circuits with moderate inrush currents, such as equipment that draws a temporarily higher current during start-up. A breaking capacity of 6 kA allows the breaker to disconnect fault currents typical of standard low-voltage networks. The breaker is intended for operation in AC systems at a rated frequency of 50/60 Hz. Its rated impulse withstand voltage Uimp is 6 kV, which is an important parameter for electrical endurance during transient overvoltage events. The conductor connection range from 1 to 25 mm² provides flexibility when integrating the device into different internal wiring schemes and distribution assemblies. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define the requirements for circuit breakers used in protection and switching of electrical circuits. Combining the 3P+N layout, 40 A rated current, C characteristic, and 6 kA breaking capacity, this modular device is appropriate for protecting three-phase lines in switchboard equipment where dependable circuit isolation and overload protection are required.
