Circuit breaker ETI ETIMAT 10 1P 4A D 10kA (2151710)

This single-pole circuit breaker from ETI’s ETIMAT 10 series is intended for protection of electrical circuits against overload and short circuit in residential, commercial, and industrial AC distribution systems. With a rated current of 4 A, it is suitable for protecting low-current lines where controlled disconnection of the circuit is required, while the D tripping characteristic makes it appropriate for loads with higher inrush currents, such as circuits with electric motors, transformers, and other devices that can generate short-term current peaks. The breaker is designed for AC networks with a rated voltage of 230/400 V and a rated frequency of 50/60 Hz, which covers standard power supply conditions used in electrical installations. Its breaking capacity of 10 kA allows the device to interrupt high fault currents during short-circuit conditions, making it suitable for use in installations where a higher prospective short-circuit current may occur. The rated impulse withstand voltage Uimp of 6 kV adds an important indication of resistance to transient overvoltages in the network. The device supports conductor cross-sections from 1 to 25 mm², which simplifies integration into typical distribution board wiring schemes. This range provides flexibility when connecting incoming and outgoing conductors in modular switchboards. Compliance with IEC/EN 60898-1 and IEC 60947-2 confirms that the breaker is designed for low-voltage protective applications and can be used in both domestic and professional electrical systems. As a modular protective device, ETIMAT 10 is suitable for installation in standard distribution cabinets alongside other circuit protection and switching equipment. It is commonly used as a local protective element for individual circuits, helping isolate faults within a specific line without affecting the operation of the rest of the installation. This makes it a practical solution for circuit-level protection in electrical networks where both overload protection and reliable short-circuit interruption are required.
