ETI ETIMAT P10 3-pole 16A D 10kA circuit breaker (1901350)

The ETI ETIMAT P10 automatic circuit breaker is intended for protection of electrical circuits against overload and short circuit in distribution boards of residential, commercial, and industrial installations. With three poles, it is suitable for three-phase lines where simultaneous switching and protection of all phases are required. The device is part of the ETIMAT P10 series and is designed for use as a modular protective device in AC networks. This model has a rated current of 16 A and a D tripping characteristic. Such a time-current curve is used in circuits with higher inrush currents, for example where connected equipment creates short-term current peaks during startup. The D characteristic helps the breaker tolerate these transient loads while still providing protection under fault conditions. The breaking capacity of 10 kA indicates the ability to interrupt high short-circuit currents, which is an important parameter for networks with increased load levels and stricter protection requirements. The breaker is rated for AC operation at 415 V and 50/60 Hz. Its rated impulse withstand voltage Uimp is 6 kV, reflecting resistance to short-duration overvoltage events. Compliance with EN/IEC 60898 confirms that the device meets the requirements for circuit breakers used in household and similar electrical installations. This standard is relevant for modular equipment installed in panel boards and switchgear assemblies. An additional practical feature is the permitted conductor cross-section of 1–25 mm², which allows connection to a wide range of wiring configurations depending on the line design and installation requirements. This makes the breaker suitable for use in electrical distribution systems where defined protection, coordinated operation, and standard-compliant installation are necessary. ETIMAT P10 can be used as a protective element for three-phase circuits in systems where the electrical load and starting conditions require a 3-pole device with 16 A rated current and 10 kA breaking capacity.
