ETI ETIMAT 6 miniature circuit breaker 1P 40A B 6kA (2111520)

ETIMAT 6 by ETI is a miniature circuit breaker designed to protect AC electrical circuits against overload and short circuit. It is intended for installation in distribution boards of residential, commercial, and light industrial facilities, where protection and switching of a single power line are required. The 1-pole design makes it suitable for single-circuit applications and takes up one module in the panel, which is important when arranging compact modular assemblies. This model is rated for 40 A and uses a B tripping characteristic. Such a release curve is typically selected for circuits with low inrush currents, including lighting circuits and standard socket circuits. The breaking capacity of 6 kA allows the device to disconnect a faulted section of the network under short-circuit conditions within the specified limits, which is an essential parameter for low-voltage protection devices used in common electrical installations. The breaker is designed for AC networks with a rated voltage of 230/400 V and an operating frequency of 50/60 Hz. These parameters match the standard conditions of household and commercial power systems. The rated impulse withstand voltage Uimp is 6 kV, which indicates resistance to short-duration overvoltage events. This characteristic is relevant in environments where switching surges may occur in the electrical distribution system. The device accepts conductors with a cross-section from 1 to 25 mm², so it can be integrated into a wide range of panel wiring configurations. Compliance with IEC/EN 60898-1 and IEC 60947-2 confirms that the product is designed in accordance with recognized standards for low-voltage circuit breakers. These standards define the technical requirements for use in protective and switching applications. ETIMAT 6 is therefore a practical solution for protecting individual lines where the rated current, tripping curve, breaking capacity, and network parameters must be matched precisely. It is suitable for modular switchboards and can be used as part of a broader circuit protection and distribution system.
