Circuit breaker ETI ETIMAT 10 1P 25A B 10kA (2121718)

ETI ETIMAT 10 is a single-pole circuit breaker designed for protection of electrical circuits against overload and short circuit in residential, commercial, and small industrial installations. It is intended for use in AC networks where local disconnection of one conductor is required, making it suitable for protecting individual single-phase lines in distribution boards and modular switchgear assemblies. This device has a rated current of 25 A, which allows it to be used for lighting circuits, socket circuits, and other single-phase loads operating within this current range. The B tripping characteristic indicates fast response to overloads and short-circuit events, so the breaker is appropriate for circuits with relatively low inrush currents. The breaking capacity of 10 kA provides protection during high short-circuit currents and supports use in installations where a higher level of fault interruption capability is required. The breaker is designed for AC operation with a rated voltage of 230/400 V and a rated frequency of 50/60 Hz. Its rated impulse withstand voltage Uimp is 6 kV, which reflects resistance to short-duration overvoltage pulses in the network. The connection range of 1–25 mm² allows conductors of different cross-sections to be used within the limits defined by the device construction, which is important when integrating it into various wiring layouts. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2, confirming conformity with recognized standards for low-voltage circuit breakers. Thanks to these technical parameters, the model can be used in distribution systems where correct coordination of rated current, tripping curve, and breaking capacity is essential for circuit protection. It is a practical solution for organizing selective protection of individual lines in modern electrical installations.
