Automatic circuit breaker ETI ETIMAT 10 3P+N 4A C 10kA (2136710)

The ETIMAT 10 series automatic circuit breaker by ETI is designed to protect AC electrical circuits against overloads and short circuits. The 3P+N configuration makes it suitable for four-wire networks where three phase conductors and the neutral conductor must be switched together. This type of device is commonly used in distribution boards of residential, commercial, and small industrial electrical installations, especially where a three-phase line with neutral needs coordinated disconnection and protection. With a rated current of 4 A, the breaker is intended for circuits with low operating load, including individual consumer groups and auxiliary lines. The C tripping characteristic allows short-term inrush currents to pass without unwanted disconnection, which is important for circuits supplying equipment with moderate starting currents. A breaking capacity of 10 kA provides disconnection of high short-circuit currents within the limits required for low-voltage networks and helps the device perform its protective function in fault conditions. The breaker is rated for 400 V AC and a frequency of 50/60 Hz, which corresponds to standard alternating-current systems. The rated impulse withstand voltage Uimp of 6 kV indicates resistance to brief overvoltage events in the electrical installation. The conductor connection range of 1 to 25 mm² allows the breaker to be integrated into different wiring schemes according to the cross-section of the installed cables and conductors. This model complies with IEC/EN 60898-1 and IEC 60947-2, standards that define the electrical and operational requirements for protective switching devices. Combined with its 3P+N design, 4 A rating, C characteristic, and 10 kA breaking capacity, the ETIMAT 10 breaker is used as a circuit protection and distribution element in AC networks where precise and stable operation of the protective apparatus is required.
