ETI ETIMAT 10 circuit breaker 3P 50A D 6kA (2155721)

The 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 of residential, commercial, and industrial facilities where switching and protective disconnection of three-phase lines is required. With three poles, the device enables simultaneous disconnection of three conductors, which is important for three-phase circuits and other arrangements that require coordinated switching. The rated current of 50 A makes this circuit breaker suitable for lines with corresponding load levels. The D tripping characteristic means the device is adapted to circuits with higher inrush currents, so it can be used with equipment that produces short-term starting peaks. The breaking capacity of 6 kA indicates the ability to interrupt fault currents within the specified limits, which is an important parameter for protection in low-voltage systems. This model is designed for AC networks with a rated operating voltage of 400 V and a frequency of 50/60 Hz. The rated impulse withstand voltage Uimp of 6 kV reflects its suitability for operation in networks where transient overvoltages may occur. The permissible conductor cross-section range is 1 to 25 mm², which provides flexibility during panel wiring and connection of conductors commonly used in switchboard assemblies. ETIMAT 10 complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its conformity with requirements for low-voltage circuit breakers. As a modular protective device, it is mounted in an electrical panel as part of the distribution system for local protection of individual lines. The combination of 3 poles, 50 A rated current, D characteristic, 6 kA breaking capacity, and AC operation makes this device suitable for three-phase power distribution circuits where controlled protection and reliable isolation are required.
