ETI ETIMAT P10 circuit breaker 1P 3A D 10kA (1901045)

ETIMAT P10 by ETI is a modular automatic circuit breaker intended for protection of AC electrical circuits against overload and short circuit. It is used in distribution boards of residential, administrative, and small commercial premises where a compact single-pole device is required to disconnect one conductor in a single-phase network. The breaker has a rated current of 3 A, which makes it suitable for low-load circuits such as control lines, lighting circuits, and other small-power loads, provided this matches the electrical design. The D tripping characteristic means the device is intended for circuits with higher inrush currents. This is important for loads that may draw short current peaks during start-up, allowing the breaker to distinguish between normal transient conditions and actual fault conditions. The breaking capacity is 10 kA, so the device can operate in networks where high short-circuit currents may occur. This parameter is especially important in switchboards, where the circuit breaker must disconnect fault currents safely. The rated AC voltage is 240 V, and the rated frequency is 50/60 Hz, which corresponds to common operating conditions in standard low-voltage installations. The nominal impulse withstand voltage Uimp is 6 kV, indicating resistance to short-term overvoltage events. The device complies with EN/IEC 60898, the standard for circuit breakers used in household and similar applications. The allowable conductor cross-section is 1–25 mm², which provides compatibility with a range of cable sizes within the specified limits and simplifies integration into different wiring layouts. ETIMAT P10 1p D3 is a practical choice for modular protection where single-pole disconnection, D curve tripping, 3 A rated current, and 10 kA breaking capacity are required. It fits into systems where the emphasis is on correct circuit protection and compliance with standard installation requirements.
