The ETI ETIMAT 10 circuit breaker is designed to protect electrical circuits against overload and short circuit in distribution boards used at residential, commercial, and industrial facilities. With three poles, it is intended for three-phase AC networks where simultaneous disconnection of all phases is required. This configuration is suitable for power circuits that need coordinated switching and protection across multiple phases. The device has a rated current of 40 A, which makes it suitable for circuits with medium to increased load. The D tripping characteristic is used for lines with high inrush currents, such as circuits supplying equipment with electric motors, transformers, and other inductive loads. This feature helps the breaker tolerate brief starting currents while still providing protection when a fault occurs. The breaking capacity of 10 kA allows the breaker to interrupt high short-circuit currents, which is important for networks with elevated fault levels. It is rated for 400 V AC and a frequency of 50/60 Hz, making it compatible with widely used low-voltage AC power systems. The rated impulse withstand voltage Uimp of 6 kV indicates resistance to transient overvoltages that may appear during switching operations or due to external disturbances. For installation and wiring, the breaker supports conductor cross-sections from 1 to 25 mm², which provides flexibility when integrating the device into different distribution and control schemes. Compliance with IEC/EN 60898-1 and IEC 60947-2 confirms that the product is designed for low-voltage circuit protection applications in accordance with established standards. Overall, this three-pole 40 A breaker with D characteristic and 10 kA breaking capacity is used where protection of three-phase circuits with demanding starting conditions is required.
