Automatic circuit breaker ETI ETIMAT 10 2P 25A B 10kA (2123718)

The ETIMAT 10 automatic circuit breaker by ETI is designed to protect electrical circuits against overloads and short-circuit currents. It is used in distribution boards and other modular low-voltage installations where circuit protection and reliable disconnection of faulty sections are required. With a two-pole design, the device allows simultaneous switching of two conductors, which is especially relevant in single-phase circuits and in separate distribution lines that must be disconnected together. This model is rated for a nominal current of 25 A, making it suitable for circuits with the corresponding load level in residential, commercial, and small industrial applications. The B tripping characteristic means the breaker responds to overloads and short circuits in circuits with moderate inrush currents. In practice, this makes it appropriate for lighting circuits, socket groups, and other consumers that do not require increased tolerance to starting currents. The breaking capacity of 10 kA provides circuit interruption under high short-circuit currents, which is an important parameter for the protection of electrical networks with elevated fault current levels. The breaker is intended for AC systems with a rated operating voltage of 400 V and a frequency of 50/60 Hz. These electrical ratings correspond to standard low-voltage installations. The device supports conductor cross-sections from 1 to 25 mm², which simplifies integration into various wiring schemes and makes it easier to select suitable conductors during installation. The rated impulse withstand voltage Uimp is 6 kV, indicating resistance to transient overvoltages that may occur in the network. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its applicability for line protection and distribution systems in accordance with recognized technical requirements. ETIMAT 10 is a modular protective device intended for use where compact installation, defined tripping behavior, and compliance with electrical protection standards are important.
