ETI ETIMAT 10 Circuit Breaker 1P 125A C 15kA (2131733)

The ETIMAT 10 circuit breaker by ETI is designed for protection of AC electrical circuits against overloads and short-circuit currents in distribution systems. With one pole, it is used in single-phase lines or in circuits where separate disconnection of one conductor is required. The rated current of 125 A makes it suitable for circuits with increased load, including feeder and power distribution lines, while the C tripping characteristic is intended for circuits with moderate inrush currents, such as those supplying equipment with electric motors or other inductive loads. The breaking capacity of 15 kA allows the device to disconnect the circuit under high short-circuit currents, which is an important parameter for low-voltage distribution networks. The breaker is rated for AC operation at 240/415 V and a frequency of 50/60 Hz, so it can be applied in typical residential, commercial, and industrial installations. The rated impulse withstand voltage Uimp of 4 kV indicates resistance to short-duration overvoltage events in the network. For conductor connection, the device supports a rated cross-section of 25–50 mm², enabling use with cables or wires of the corresponding size in power circuits. This should be taken into account when selecting wiring accessories and planning the assembly of switchboards. The device complies with IEC/EN 60947-2, the standard that defines technical and operational requirements for low-voltage circuit breakers. ETIMAT 10 is suitable for installation in distribution boards as part of the protection system for supply lines, power circuits, and individual consumer groups. Its combination of 1-pole design, 125 A rating, C curve, 15 kA breaking capacity, AC operation, and support for 25–50 mm² conductors makes it a practical choice where reliable circuit isolation and compatibility with standard low-voltage distribution equipment are required.
