Overcurrent circuit breaker ETIMAT 10 3P D10 002155714

ETIMAT 10 3P D10 overcurrent circuit breaker is a reliable protection for electrical installations, suitable for residential buildings, public utility facilities and industrial plants. It provides effective protection against the effects of short circuits and overloads, guaranteeing safety of use. The design of this circuit breaker allows for the installation of additional auxiliary contacts and an overcurrent release, which increases its functionality and adapts it to the specific needs of the installation.

Characteristics and application

ETIMAT 10 circuit breakers, thanks to their D characteristic, are particularly recommended for protecting circuits with receivers with high starting current – such as motors or transformers. The D characteristic allows them to react more slowly to short current surges, while effectively protecting against overloads and short circuits. The rated current of 10A makes it an ideal choice for circuits with medium power consumption. The three-pole design provides comprehensive protection in three-phase systems.

Construction and mounting

The ETIMAT 10 circuit breaker is characterized by a width of 3 modules, which facilitates its mounting on a standard TH35 rail. The possibility of connecting wires with a cross-section from 1 to 25 mm² (solid or stranded) provides flexibility in choosing the power supply wires. An additional advantage is the possibility of powering from the top and bottom, as well as double connection of the insulating busbar – which facilitates installation in various configurations. The contact position indicator and the possibility of sealing the lever in the "On" and "Off" positions increase safety and reliability.

Technical parameters and compliance with standards

The circuit breaker meets the requirements of IEC/EN 60898-1 and IEC 60947-2 standards, which confirms its high quality and reliability. The rated short-circuit breaking capacity Icn is 10 kA at 230V and 400V, and Icu is 15 kA at the same voltages. The degree of protection IP20 provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm. The circuit breaker can operate in an ambient temperature from -25°C to +55°C. The rated insulation voltage Ui is 500V and the impulse voltage Uimp is 6kV. The surge category is III and the pollution degree is III.
