ETI ETIMAT P10 circuit breaker 2P 50A D 10kA (1901255)

The ETIMAT P10 series circuit breaker by ETI is designed to protect low-voltage electrical circuits against overloads and short circuits in residential, commercial, and small industrial distribution systems. Its 2-pole design allows simultaneous switching of two conductors, which is appropriate for circuits where both poles need to be disconnected together. This device is rated for a current of 50 A, making it suitable for circuits with higher load levels. The D tripping characteristic indicates use in circuits with pronounced inrush currents, such as equipment that briefly draws a current higher than its normal operating value during startup. For this reason, the breaker can be used where standard tripping curves would be too sensitive to transient current peaks. The breaking capacity of 10 kA means the device is intended to interrupt high short-circuit currents within the limits of the electrical network for which it is selected. It operates on AC systems with a rated voltage of 400 V and a frequency of 50/60 Hz, which corresponds to common supply conditions in low-voltage installations. The rated impulse withstand voltage Uimp is 6 kV, indicating resistance to short-term overvoltages that may occur in the network. Installation and conductor selection should also take into account the rated conductor cross-section of 125 mm². This parameter is important during panel design and wiring, as it helps ensure proper connection of the breaker within the distribution board. The product complies with EN/IEC 60898, the standard governing key requirements for circuit breakers used in the protection of low-voltage circuits. ETIMAT P10 is a modular protective device intended for installation in an electrical panel. It combines 2-pole switching, D curve behavior, 50 A rated current, and 10 kA breaking capacity, making it suitable for circuits where both higher load handling and reliable response to inrush currents are required.
