ETI ETIMAT 10 miniature circuit breaker 2P 25A D 10kA (2153718)

ETIMAT 10 from ETI is a modular circuit breaker designed for protection of electrical circuits against overloads and short circuits in distribution boards of residential, commercial, and small industrial installations. With two poles, it is intended for simultaneous disconnection of a two-pole line, which is important in circuits where both conductors must be switched off together. The device is rated at 25A and uses a D tripping characteristic. This makes it suitable for circuits with higher inrush currents, such as loads that draw a short-term current significantly above the operating level during start-up. The breaking capacity of 10kA allows the breaker to interrupt high fault currents, which is relevant for networks with increased short-circuit levels. The breaker operates in AC systems with a rated voltage of 400V and a frequency of 50Hz/60Hz. From the electrical and installation point of view, the model has a rated impulse withstand voltage Uimp of 6kV, which indicates resistance to short-term overvoltage events. The permissible conductor cross-section is 1 mm² to 25 mm², so the device can be connected with a wide range of wiring sizes within this limit. This supports use in standard low-voltage distribution circuits where conductor selection must match the protected line. The product complies with IEC/EN 60898-1 and IEC 60947-2, confirming its conformity with recognized standards for low-voltage protective switching devices. In practice, ETIMAT 10 2P 25A D 10kA is used as part of the protective equipment in electrical panels where a combination of two-pole isolation, high breaking capacity, and D-curve response is required. It is appropriate for dedicated line protection in installations where operating conditions call for stable tripping behavior with loads that have pronounced starting currents.
