ETI ETIMAT 10 automatic circuit breaker 3P+N 63A C 6kA (2136722)

The ETIMAT 10 series circuit breaker from ETI is intended for protecting electrical circuits against overload and short circuit. It is used in distribution boards of residential, commercial, and small industrial facilities where three-phase lines with neutral conductors must be controlled and protected. The device is suitable for the incoming and outgoing protection of circuits that require a clear trip response and operation within standard low-voltage installations. This model has a 3+N pole configuration, meaning three poles are used for the phase conductors and one pole is provided for neutral switching. The rated current is 63 A, so the breaker is designed for circuits with the corresponding load level. The C tripping characteristic makes it suitable for networks with moderate inrush currents, including circuits supplying electric motors, power units, and other equipment that briefly draws a higher starting current. The breaking capacity of 6 kA defines the maximum short-circuit current the device can interrupt under the specified conditions. The breaker is designed for AC systems with a rated operating voltage of 400 V and a frequency of 50/60 Hz. The rated impulse withstand voltage Uimp is 6 kV, which is relevant for electrical networks exposed to switching surges. Conductor connection is permitted for cross-sections from 1 mm² to 25 mm², allowing use with common cable types in switchgear assemblies. The device complies with IEC/EN 60898-1 and IEC 60947-2 standards, which set the requirements for low-voltage circuit breakers. These technical characteristics make the ETIMAT 10 a practical solution for protective and switching functions in three-phase installations where correct tripping, compatibility with neutral switching, and operation in a modular distribution system are required.
