ETI ETIMAT P10 Circuit Breaker 3P+N 50A D 10kA (1901455)

The ETIMAT P10 circuit breaker from ETI is designed to protect electrical circuits against overloads and short circuits in three-phase networks with a neutral conductor. It is used in distribution boards in residential, commercial, and industrial installations where circuit protection and switching are required for lines with higher inrush currents or loads that briefly exceed the operating current during start-up. This model has a 3P+N configuration, meaning three protected poles plus a neutral pole. Such construction allows it to be used in four-wire networks and ensures simultaneous switching of the phase conductors and neutral according to the connection scheme. The rated current is 50 A, which makes the device suitable for protecting feeder or group circuits with corresponding current demand. The D tripping characteristic indicates suitability for circuits with high inrush currents, such as electric motors, transformers, and other equipment that draws a significantly higher current for a short time during starting. The breaking capacity of 10 kA means the device is designed to interrupt substantial short-circuit currents, which is important in networks with elevated fault current levels. This provides an appropriate safety margin for coordination with the electrical installation parameters. The breaker’s modular design allows DIN rail mounting, simplifying installation in standard distribution boards and ensuring compatibility with other modular devices. ETIMAT P10 3P+N 50A D 10kA is a solution for the protection and switching of power circuits where four-pole disconnection, high breaking capacity, and a D tripping curve are required.
