ETI ETIMAT 6 Circuit Breaker 2P 63A C 6kA (2143522)

This ETI ETIMAT 6 circuit breaker is intended for protection of electrical circuits against overload and short circuit in residential, commercial, and industrial distribution boards. With a 2-pole design, it allows simultaneous switching of two conductors, which is appropriate for AC lines in 400 V networks where two-pole disconnection is required. The device is suitable for use as part of modular low-voltage protection systems in panel boards, where circuit isolation and fault protection are needed. The unit is rated at 63 A and uses a C tripping characteristic. This time-current curve is typically selected for circuits with moderate inrush currents, helping the breaker withstand short starting peaks while still providing protection against sustained overloads and short-circuit conditions. A breaking capacity of 6 kA indicates the maximum prospective short-circuit current the device can interrupt under the specified conditions, making it suitable for standard distribution applications. Electrical ratings include 400 V AC rated voltage, 6 kV rated impulse withstand voltage (Uimp), and operation at 50/60 Hz. These parameters confirm compatibility with common AC supply systems and distribution networks. The rated conductor cross-section is 1–25 mm², which supports connection of a wide range of cables and conductors used in wiring and panel installations. The breaker complies with IEC/EN 60898-1 and IEC 60947-2, confirming conformity with recognized standards for circuit protection devices. Such compliance is important for installations where equipment must meet defined requirements for performance, installation, and operating conditions. In practical use, the ETIMAT 6 series breaker is applied to protect feeder and branch circuits, as well as consumer groups that require reliable two-pole disconnection and a 63 A rating in AC systems.
