Circuit breaker ETI ETIMAT P10 2P 20A B 10kA (1901211)

ETI ETIMAT P10 is an automatic circuit breaker designed to protect electrical lines against overloads and short circuits. It is intended for use in distribution boards of residential, commercial, and light industrial installations where reliable disconnection of a two-pole circuit is required. With 2 poles, the device is suitable for simultaneous switching of two conductors in AC networks. The breaker is rated at 20 A and has tripping characteristic B. This characteristic is typically used in circuits with low inrush currents, such as lighting circuits and other standard household loads. In this way, the device responds promptly to overcurrent while allowing normal operation of circuits that do not have significant starting peaks. The breaking capacity of 10 kA enables the breaker to interrupt high short-circuit currents, which is an important parameter for electrical systems with elevated protection requirements. The device is designed for AC operation with a rated voltage of 415 V and a rated frequency of 50/60 Hz, making it suitable for common low-voltage distribution applications. The rated impulse withstand voltage Uimp is 6 kV, which indicates resistance to transient overvoltages in the network. Installation is carried out in a modular distribution board in accordance with EN/IEC 60898. This standard defines the basic requirements for miniature circuit breakers and ensures compatibility with typical modular electrical equipment used in modern switchboards. The supported conductor cross-section range from 1 to 25 mm² provides flexibility during wiring and allows the breaker to be integrated into circuits with different cable sizes. ETIMAT P10 2P 20A B 10kA is a practical solution for protecting two-pole AC lines where the key parameters are a 20 A current rating, B tripping curve, 10 kA breaking capacity, and standard modular installation.
