Circuit breaker ETI ETIMAT 10 3P+N 50A C 6kA (2136721)

ETIMAT 10 by ETI is a circuit breaker designed to protect electrical circuits against overloads and short-circuit currents. It is intended for installation in distribution boards and can be used in residential, commercial, and small industrial electrical systems where three-phase supply with a neutral conductor is required. The 3P+N pole configuration makes it suitable for circuits that need to switch and protect all three phases together with the neutral line. The device has a rated current of 50 A, which allows it to be used on circuits with elevated load levels. The C tripping characteristic is commonly applied in circuits with moderate inrush currents, for example where loads with electric motors or other equipment with short-term start-up surges are connected. This makes the breaker appropriate for a wide range of feeder and distribution applications in low-voltage networks. A breaking capacity of 6 kA provides the ability to disconnect fault currents within the limits typical for many standard AC installations. The breaker is rated for AC operation at 400 V and 50/60 Hz, so it is compatible with common alternating-current power systems. The nominal impulse withstand voltage Uimp of 6 kV indicates resistance to short-duration voltage surges, which is an important parameter for stable operation in electrical panels. Connection of conductors is allowed within a cross-section range from 1 to 25 mm², which simplifies integration into different wiring schemes and facilitates selection of suitable cables during panel assembly. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define requirements for circuit breakers used in household and professional electrical installations. As a result, this model can be selected as a line-protection device in switchboards where reliable protection against overload and short circuit, together with three-phase plus neutral switching, is required.
