Circuit breaker ETI ETIMAT 10 1P 25A D 10kA (2151718)

ETIMAT 10 by ETI is a single-pole circuit breaker designed to protect electrical circuits from overload and short-circuit currents. Its 1P construction makes it suitable for single-phase lines and for installation in a distribution board where compact modular protection is required. With a rated current of 25 A, the device is intended for circuits with corresponding load levels, including feeder lines for consumer groups in residential, commercial, and other AC installations. The D tripping characteristic is used for circuits with elevated inrush currents. This makes the breaker appropriate for applications where connected equipment can generate short-term current peaks during start-up. The breaking capacity of 10 kA allows the device to disconnect the circuit under high short-circuit current conditions, which is an important parameter for networks with increased protection requirements. The breaker is designed for AC systems with a rated voltage of 230/400 V and a rated frequency of 50/60 Hz. It also has a rated impulse withstand voltage Uimp of 6 kV, which reflects its ability to withstand transient overvoltage events. The supported conductor cross-section ranges from 1 to 25 mm², so the device can be used with conductors that match this installation range and project specification. Compliance with IEC/EN 60898-1 and IEC 60947-2 confirms that the device meets the requirements applicable to modular protection and switching equipment. In practice, this circuit breaker is used as a protective element for individual lines in electrical distribution systems where correct tripping behavior, compatibility with AC networks, and adherence to international standards are essential.
