Automatic circuit breaker ETI ETIMAT 10 3P 63A C 6kA (2135722)

ETIMAT 10 by ETI is a miniature circuit breaker designed for protection of electrical circuits against overload and short circuit in household, commercial, and small industrial low-voltage networks. With three poles, it is suitable for switching three-phase lines as well as circuits where simultaneous disconnection of several conductors is required. The rated current of 63 A makes this device applicable in circuits with increased load, where stable line protection is needed without unnecessary tripping. The C tripping characteristic indicates suitability for circuits with moderate inrush currents. This is important for lines supplying equipment with electric motors, transformer power supplies, or other loads that draw a brief starting current at switch-on. The breaking capacity of 6 kA allows the breaker to interrupt fault currents typical of most modern low-voltage AC systems, helping maintain circuit protection under short-circuit conditions. The device is designed for AC voltage with a rated operating voltage of 400 V and a rated frequency of 50/60 Hz, which makes it compatible with standard alternating-current installations. The breaker complies with IEC/EN 60898-1 and IEC 60947-2, confirming conformity with requirements for modular protective devices. The rated impulse withstand voltage Uimp of 6 kV reflects resistance to short-duration overvoltages that may occur in the network. The permitted conductor cross-section range of 1 to 25 mm² provides compatibility with commonly used wiring sizes in distribution boards and allows flexible installation within electrical assemblies. This circuit breaker is used as a line or group protection element in distribution panels where three-pole disconnection, compact modular format, and parameters adapted for AC networks are required. It is a practical solution for protecting power and distribution circuits in installations where coordinated electrical protection and standard DIN-rail modular equipment are used.
