ETI ETIMAT 6 circuit breaker 3P 20A D 6kA (2164517)

The ETI ETIMAT 6 circuit breaker is designed to protect electrical lines against overload and short circuit in distribution boards used in residential, commercial, and industrial installations. With three poles, it is suitable for three-phase circuits where simultaneous disconnection of all phases is required. The rated current of 20 A makes it appropriate for lines with moderate load, while the D tripping characteristic is intended for circuits with higher inrush currents, such as those supplying electric motors, transformers, or other equipment that generates short-term current peaks. This modular protective device has a breaking capacity of 6 kA, which defines its ability to interrupt fault currents in low-voltage networks. It operates on AC networks with a rated voltage of 400 V and a frequency of 50/60 Hz, making it suitable for standard power distribution applications. The rated impulse withstand voltage Uimp of 6 kV indicates resistance to switching and transient overvoltages, which is important for electrical systems exposed to pulse disturbances. The model complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its alignment with the requirements for low-voltage modular protection equipment. The rated conductor cross-section range of 1 to 25 mm² provides flexibility during installation and allows connection of a wide selection of cables and conductors used in distribution assemblies and control panels. ETIMAT 6 is a practical choice for protecting three-phase circuits where reliable disconnection under overload or short-circuit conditions is required. It is especially useful in applications involving equipment with elevated start-up currents, where the D curve helps avoid unnecessary tripping during normal operation. The combination of 3 poles, 20 A rated current, D characteristic, 6 kA breaking capacity, AC operation, 400 V rated voltage, and compliance with recognized standards makes this circuit breaker suitable for a broad range of electrical installation tasks.
