The ETIMAT 10 series circuit breaker by ETI is designed to protect electrical circuits against overloads and short circuits in distribution boards used in residential, commercial, and small industrial installations. With a three-pole design, it is suitable for protecting three-phase lines where simultaneous disconnection of all phases is required. This makes it applicable in supply circuits for equipment, socket groups, and small power loads, provided the network design calls for three-pole protection. The rated current is 4 A, so the device is intended for circuits with relatively low operating loads. The C tripping characteristic means the breaker can tolerate short-term inrush currents that occur when starting electric motors, transformers, or other equipment with moderate starting currents. This feature is important in circuits where brief current peaks should not cause nuisance tripping. The breaking capacity of 10 kA allows the device to interrupt high short-circuit currents, which is especially relevant in switchboard applications with elevated fault current levels. This model operates in AC circuits with a rated voltage of 400 V and a frequency of 50/60 Hz. The rated impulse withstand voltage, Uimp, is 6 kV, indicating resistance to short-duration overvoltage events. These electrical ratings make the breaker suitable for use in low-voltage installations where consistent circuit protection and compliance with standard requirements are necessary. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define the requirements for low-voltage circuit breakers. The accepted conductor cross-section range of 1–25 mm² provides flexibility during installation and allows connection of conductors with different sizes in distribution equipment. The modular format supports installation in standard electrical panels on DIN rail systems together with other modular devices. Overall, this is a three-pole protective device for three-phase networks, combining a 4 A rated current, C tripping curve, and 10 kA breaking capacity. It is used as part of circuit protection systems where reliable interruption of overload and fault conditions, correct phase disconnection, and compliance with established electrical standards are required.
