ETI ETIMAT 10 miniature circuit breaker 1P 20A D 10kA (2151717)

The ETIMAT 10 miniature circuit breaker from ETI is designed to protect electrical circuits against overload and short-circuit currents. It is intended for installation in distribution boards of residential, commercial, and small industrial electrical systems, where protection of a single outgoing line is required. Thanks to its 1-pole design, the device is suitable for single-phase circuits or for individual protection of a dedicated branch of the network. This breaker has a rated current of 20 A, which makes it appropriate for circuits with corresponding load requirements. The D tripping characteristic indicates use in circuits with elevated inrush currents, for example where equipment may draw a short-term current peak during start-up. Such behavior is important when the protected line supplies devices with motors or other loads that briefly exceed the steady operating current. The breaking capacity of 10 kA provides the ability to disconnect the circuit under high short-circuit current conditions. This parameter is especially important in systems where a higher prospective fault current may occur and where reliable interruption of the fault is required to help protect the wiring and connected equipment. The breaker operates in AC systems with a rated voltage of 230/400 V and a rated frequency of 50/60 Hz, making it suitable for common low-voltage installation environments. The unit also features a rated impulse withstand voltage Uimp of 6 kV, which reflects resistance to short-duration overvoltage events in the network. The permissible conductor cross-section range of 1–25 mm² allows connection with a wide selection of cable and wire sizes within the specified limits. In addition, compliance with IEC/EN 60898-1 and IEC 60947-2 confirms conformity with the standards used for modular protective switching devices. Overall, ETIMAT 10 is a module-type protective device for organizing overcurrent and short-circuit protection in switchgear assemblies. Its electrical ratings, AC compatibility, and standard-compliant design make it suitable for use in distribution systems where a single line must be protected and disconnected under fault conditions.
