ETI ETIMAT 10 Circuit Breaker 1P 20A B 10kA (2121717)

ETIMAT 10 by ETI is a single-pole circuit breaker intended for protection of electrical circuits against overload and short-circuit conditions in residential, administrative, and small commercial installations. Its one-pole design is suited for switching and protecting a single line, which makes it a practical option for lighting circuits and individual socket circuits where independent line protection is required. The rated current of 20 A allows the device to be used in circuits with moderate load. The B tripping characteristic means the breaker responds to overload and short-circuit currents in networks with low inrush currents, so it is typically applied in standard household and lighting applications rather than in circuits with significant motor starting currents. The breaking capacity of 10 kA provides the ability to disconnect the circuit under high short-circuit current conditions, which is important for distribution systems where higher fault levels may be present. This model is designed for AC networks. Its rated AC voltage is 230/400 V, and the rated frequency is 50/60 Hz, which corresponds to common supply parameters in low-voltage electrical systems. The rated impulse withstand voltage Uimp of 6 kV indicates resistance to short-duration overvoltage events that can occur in the installation. These technical parameters make the device suitable for use in distribution boards as part of the main line protection scheme. The breaker supports conductor cross-sections from 1 to 25 mm², which broadens installation options and allows connection to different cable types within the specified range. Compliance with IEC/EN 60898-1 and IEC 60947-2 standards confirms its applicability in low-voltage distribution systems and modular switchboards. Overall, this is a protective switching device for circuits where stable overcurrent and short-circuit protection is required, with technical characteristics aligned with common building electrical networks.
