ETI ETIMAT 10 Circuit Breaker 3P 40A B 10kA (2125720)

ETIMAT 10 by ETI is a three-pole automatic circuit breaker designed to protect electrical circuits against overloads and short-circuit currents. It is intended for installation in distribution boards of residential, commercial, and industrial facilities where reliable switching and protection of AC power lines are required. With three poles, the device is suitable for three-phase circuits and for applications where simultaneous disconnection of the line is needed. The breaker has a rated current of 40 A and B tripping characteristic. This trip curve is used in circuits with moderate inrush currents, such as standard distribution lines and many general-purpose loads. The breaking capacity of 10 kA enables the device to interrupt high fault currents, which is an important parameter for protection in networks with elevated short-circuit levels. The rated AC voltage is 400 V, while the rated frequency is 50/60 Hz, so the unit can be used in common mains supply systems. Additional electrical withstand parameters include a rated impulse withstand voltage, Uimp, of 6 kV. This characteristic reflects the breaker’s ability to tolerate transient overvoltages that may occur in the network. The permissible conductor cross-section for connection ranges from 1 mm² to 25 mm², which supports use in standard wiring and simplifies integration into typical switchboard assemblies. The product complies with IEC/EN 60898-1 and IEC 60947-2 standards, confirming its classification and application within modular protective devices. As a modular circuit breaker, it is designed for mounting in an electrical panel and can be incorporated into distribution systems where compact layout and functional protection are important. ETIMAT 10 is therefore suitable for protecting group circuits and three-phase consumers operating on alternating current.
