ETI ETIMAT 6 Circuit Breaker 3P 50A D 6kA (2164521)

The ETIMAT 6 series automatic circuit breaker by ETI is designed to protect electrical lines against overload and short circuit. It is intended for installation in distribution boards of residential, commercial, and industrial facilities where three-phase circuits require controlled disconnection and reliable protection. With 3 poles, the device enables simultaneous switching of three phase conductors, making it suitable for feeders and power circuits with three-phase loads. The rated current is 50 A, which defines the area of application for circuits with the corresponding load level. The D tripping characteristic indicates suitability for circuits with higher inrush currents, such as lines supplying electric motors, transformers, or other equipment that draws a short-term current peak during startup. This characteristic helps the breaker respond correctly in demanding operating conditions without unnecessary tripping during normal start-up processes. The breaking capacity of 6 kA allows the device to interrupt fault currents within the specified range in the event of a short circuit. The breaker is designed for AC systems with a rated voltage of 400 V and a rated frequency of 50/60 Hz. In addition, the nominal impulse withstand voltage Uimp is 6 kV, which is an important parameter for resistance to transient overvoltages in low-voltage installations. Another practical feature is the permitted conductor cross-section of 1 to 25 mm², which provides compatibility with widely used cable and wire terminations. This simplifies integration into standard low-voltage distribution systems and supports connection of different conductor sizes within the specified range. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its conformity with the technical requirements applicable to automatic circuit breakers in different installation contexts. ETIMAT 6 3P 50A D 6kA is a modular protective device for three-phase circuits where a combination of 50 A nominal current, D characteristic, 6 kA breaking capacity, and AC operation at 400 V is required.
