ETI ETIMAT P10 Circuit Breaker 3P 25A B 10kA (1901312)

This three-pole circuit breaker from ETI’s ETIMAT P10 series is designed to protect AC electrical circuits against overloads and short circuits. It is intended for installation in distribution boards used in residential, commercial, and small industrial facilities where simultaneous switching of three phases is required. With a rated current of 25 A, the device is suitable for medium-load lines, while the B tripping characteristic makes it appropriate for circuits with relatively low inrush currents, such as lighting and general socket groups. The breaking capacity of 10 kA allows the breaker to disconnect the circuit under high short-circuit currents, which is an important parameter for protecting low-voltage networks. The device is rated for 415 V AC and operates at 50/60 Hz, so it can be used in standard three-phase systems. The rated impulse withstand voltage, Uimp, is 6 kV, indicating resistance to short-term overvoltage events that may occur during switching operations or due to transient disturbances. The model complies with EN/IEC 60898, confirming its suitability for modular low-voltage installations. This standard is widely used for circuit breakers intended for distribution boards in everyday electrical systems. The connection range of 1–25 mm² makes it possible to connect conductors of different cross-sections within the specified technical limits, which helps when assembling or servicing distribution circuits. As a modular protective device, ETIMAT P10 is installed on a DIN rail together with other switching and protection components. Its three-pole design ensures coordinated disconnection of the phases, which is especially relevant for three-phase loads and feeder lines. The combination of a 25 A rating, B curve, 10 kA breaking capacity, and 415 V AC operating voltage defines the breaker’s application in circuits where controlled protection and clear electrical characteristics are required. ETIMAT P10 3p B25 is a practical choice for organizing protection of three-phase lines in boards that must meet defined technical and standards-based requirements.
