ETI ETIMAT P10 automatic circuit breaker 3P 0.5A C 10kA (1901321)

The ETIMAT P10 automatic circuit breaker from ETI is designed to protect AC electrical circuits against overloads and short circuits in distribution boards used in residential, commercial, and industrial installations. Its three-pole design allows simultaneous disconnection of all protected conductors, which is important for multi-pole or three-phase circuits where coordinated isolation is required. This model is rated for a nominal current of 0.5 A, so it is intended for circuits with very low operating load or for individual auxiliary lines that require precise overcurrent protection. The C tripping characteristic means the device tolerates short-term inrush currents and responds appropriately to overload and fault conditions. Such a characteristic is suitable for circuits where moderate starting currents may occur during equipment startup. The breaking capacity of 10 kA provides the ability to interrupt high short-circuit currents, which is a key parameter for reliable operation in protected electrical systems. The breaker is designed for AC voltage networks with a rated operating voltage of 415 V and a rated frequency of 50/60 Hz, making it suitable for common three-phase supply systems and other AC applications within the specified limits. Additional electrical endurance parameters include a rated impulse withstand voltage Uimp of 6 kV, which reflects resistance to short-duration voltage surges in the distribution network. The device complies with EN/IEC 60898, a standard that defines requirements for circuit breakers used in household and similar installations, confirming its intended use in standard low-voltage protective applications. For installation and wiring, the breaker supports conductor cross-sections from 1 mm² to 25 mm², which provides flexibility when connecting different cable sizes within the permitted mounting practice. Overall, this ETI ETIMAT P10 circuit breaker is a functional solution for main or group protection of electrical lines where a three-pole configuration, 0.5 A rated current, C characteristic, and 10 kA breaking capacity are required.
