The ETIMAT 10 series circuit breaker by ETI is designed to protect AC electrical circuits against overloads and short circuits. It is used in distribution boards of residential, commercial, and small industrial installations where two-pole switching and standard modular protection are required. The device is suitable for low-voltage networks and is intended for installation as part of the circuit protection system. This model is rated for a nominal current of 50 A and has a B tripping characteristic. Such a characteristic is appropriate for circuits with relatively low inrush currents, including lighting and other lines where fast response to overload conditions is important. The two-pole design enables simultaneous switching of two conductors, which is relevant for circuit arrangements that require disconnection of both poles together. The breaker operates in AC systems with a nominal voltage of 400 V and a frequency of 50/60 Hz, which makes it compatible with common supply configurations used in building electrical networks. The breaking capacity of 6 kA defines the device’s ability to interrupt fault currents in typical low-voltage installations. In addition, the rated impulse withstand voltage Uimp is 6 kV, which is important for operation in networks exposed to transient overvoltages. The breaker supports conductor cross-sections from 1 to 25 mm², simplifying termination in distribution panels and allowing use with a wide range of wiring solutions. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its intended use as a circuit breaker for low-voltage electrical installations. With its 2-pole construction, 50 A rating, B curve, and 6 kA breaking capacity, this device is appropriate for protecting branch circuits where controlled and repeatable tripping under fault conditions is required.
