ETI ETIMAT 10 Circuit Breaker 1P 50A C 6kA (2131721)

ETIMAT 10 by ETI is a modular circuit breaker designed to protect electrical circuits against overload and short circuit. It is used in distribution boards of residential, commercial, and small industrial installations where a single line requires switching and protection. With a 1-pole design, this device is intended for single-phase circuits and individual consumer groups operating within the specified AC network parameters. The breaker is rated at 50 A, which makes it suitable for circuits with higher load demands. The C tripping characteristic indicates compatibility with lines that may experience short-duration inrush currents, such as circuits supplying electric motors or other equipment with increased starting current. The breaking capacity of 6 kA provides interruption of fault currents within the range required for many domestic and commercial low-voltage systems. The device is designed for AC operation with a rated voltage of 230/400 V and a frequency of 50/60 Hz. Its rated impulse withstand voltage, Uimp, is 6 kV, which confirms resistance to impulse overvoltages typical of distribution systems. The permitted conductor cross-section is 1–25 mm², allowing connection with a wide range of wiring and cable sizes within the stated limits. Compliance with IEC/EN 60898-1 and IEC 60947-2 standards confirms that the breaker is intended for use in low-voltage modular installations. It is a practical solution for building and protecting electrical lines in panels where safe circuit disconnection and fault-current protection are required. The combination of 50 A rated current, C characteristic, 6 kA breaking capacity, and standardized modular application makes this circuit breaker suitable for circuits with corresponding electrical loads.
