Overcurrent circuit breaker ETIMAT 10 1P+N 20A 002122717

Circuit breaker ETIMAT 10 is a reliable and proven solution for protecting electrical installations. Designed for use in residential buildings, public and industrial facilities, it provides effective protection against the effects of short circuits and overloads. The breaker's design allows for mounting on a TH35 rail, making installation and replacement easier.

Characteristics and Application

The ETIMAT 10 circuit breaker with characteristic B is ideal for circuits with moderate inrush currents. Characteristic B means that the breaker reacts quickly to overloads, but is more tolerant to short-term current surges, which is important when connecting devices with electric motors or other inductive loads. A rated current of 20A makes it suitable for protecting typical lighting and socket circuits in residential buildings. The single-pole model with an additional neutral pole (1P+N) provides comprehensive protection.

Construction and Installation

The circuit breaker has been designed with ease of installation and use in mind. The possibility of double connection of the insulating busbar (top and bottom) increases installation flexibility. The contact position indicator allows for quick visual control of the breaker's status. The switching lever has a clear "ON/OFF" marking, and the ability to seal it in the "On" or "Off" position increases safety and prevents accidental change of state. It accepts wire cross-sections from 1 to 25 mm², both solid and stranded, ensuring compatibility with various types of installations.

Parameters and Safety

The ETIMAT 10 circuit breaker meets the requirements of IEC/EN 60898-1 and IEC 60947-2 standards, guaranteeing its reliability and safety. The rated short-circuit breaking capacity (Icn) is 10 kA at 230/400 V, and the Icu capacity reaches 15 kA at 230/400 V according to IEC 60947-2 – these are key parameters determining resistance to the effects of short circuits. The IP20 protection degree provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm. The ambient temperature in operating conditions is in the range of -25°C to +55°C, which allows the breaker to be used in various environmental conditions. Additionally, the circuit breaker has a rated insulation voltage Ui of 500V and energy limitation class 3 and overvoltage category III – important aspects for ensuring the safety of the electrical installation.
