Automatic circuit breaker ETI ETIMAT 6 2P 50A D 6kA (2163521)

ETIMAT 6 by ETI is an automatic circuit breaker designed to protect electrical circuits against overload and short circuit in AC installations. With two poles, it is suitable for switching and protecting single-phase and two-phase circuits in distribution boards, where simultaneous disconnection of the line is required. The rated current of 50 A makes this device appropriate for circuits with increased load, where reliable interruption is needed when operating current exceeds permissible values. The D tripping characteristic indicates suitability for circuits with high inrush currents. This is important for equipment that draws short-term current peaks during start-up, such as loads with motors or other devices with pronounced starting currents. In such applications, the breaker helps maintain protection without nuisance tripping during normal operation. The breaking capacity of 6 kA defines its ability to disconnect short-circuit currents within the limits typical for residential and part of commercial low-voltage networks. The breaker is intended for operation in AC networks with a rated voltage of 400 V and a frequency of 50/60 Hz. Its rated impulse withstand voltage Uimp is 6 kV, which reflects resistance to short-term overvoltage events in the electrical system. The conductor connection range of 1 to 25 mm² provides flexibility during installation and makes it possible to integrate the device into different wiring schemes using conductors of the specified cross-section. Compliance with IEC/EN 60898-1 and IEC 60947-2 confirms that the device meets the requirements applicable to low-voltage automatic circuit breakers. This makes the ETIMAT 6 suitable for use in residential, administrative, and industrial electrical installations as a line protection element in modular distribution equipment. The combination of two-pole design, 50 A nominal current, D curve, 6 kA breaking capacity, and AC operation parameters provides the functional characteristics required for circuit protection and switching in standard distribution systems.
