ETI ETIMAT 10 circuit breaker 1P D 0.5 A 10 kA (2151701)

The ETIMAT 10 series automatic circuit breaker from ETI is intended for protection of AC electrical circuits against overload and short circuit. With one pole and a rated current of 0.5 A, it is used in low-load circuits where precise current limitation and stable line protection are required. Such a rating makes the device suitable for auxiliary circuits, control lines, and other branches that need careful current monitoring rather than high-current distribution. The D tripping characteristic indicates that the breaker is designed for circuits with elevated inrush currents. This is important where short-term current surges may occur during equipment start-up. The breaking capacity of 10 kA provides disconnection under significant short-circuit conditions, which is relevant for distribution systems with higher fault-current demands. The rated impulse withstand voltage Uimp of 6 kV adds resistance to transient overvoltages in the network. The breaker is designed for AC networks with a rated voltage of 230/400 V and a frequency of 50/60 Hz, so it can be integrated into standard low-voltage panels used in residential and commercial installations. Its connection range supports conductor cross-sections from 1 to 25 mm², which simplifies wiring in different mounting schemes and makes the device adaptable to various electrical assemblies. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2, confirming conformity with the requirements applied to low-voltage modular protective equipment. This standard compliance is important when selecting a device for distribution boards where compatibility with established installation practices and electrical protection rules is required. In practical use, the breaker serves as a protective element for individual branches of an electrical network, helping isolate fault conditions and maintain the operation of the rest of the installation.
