Overcurrent circuit breaker ETIMAT 10 3P+N C25 002136718

Overcurrent circuit breaker ETIMAT 10 3P+N C25 is a reliable protection for electrical installations, used in residential buildings, public facilities, and industrial plants. It provides effective protection against the effects of short circuits and overloads, protecting electrical circuits and connected devices. The 3P+N (three-pole plus neutral) design makes this circuit breaker ideal for protecting multi-phase circuits.

Characteristics and application

The ETIMAT 10 circuit breaker features a C tripping characteristic, meaning it responds to overloads of 5 to 10 times the rated current. This characteristic is particularly useful in circuits with receivers with high starting current, such as electric motors. The rated current of 25A allows for the protection of circuits with medium load. This circuit breaker meets the requirements of IEC/EN 60898-1 and IEC 60947-2 standards, guaranteeing its safety and reliability.

Construction and parameters

The circuit breaker is designed for mounting on a TH35 rail, which facilitates its installation and replacement. Its width of 4 modules allows for efficient use of space in the distribution board. The housing with a protection degree of IP20 protects against accidental contact and the ingress of solid objects larger than 12.5 mm. The rated short-circuit breaking capacity (Icn) is 10 kA at 230/400 V, and the Icu capacity according to IEC 60947-2 is as high as 15 kA at 230 V and 15 kA at 400 V – these are key parameters for ensuring the safety of the installation in the event of a short circuit. The possibility of connecting wires with a cross-section from 1 to 25 mm² provides flexibility when selecting power cables. Additionally, the circuit breaker can operate at temperatures from -25°C to +55°C, making it suitable for use in various environmental conditions.

• Rated insulation voltage Ui is as high as 500V, which increases the safety margin
• Overvoltage category III and pollution degree III indicate the possibility of use in difficult industrial conditions
• The possibility of mounting auxiliary contacts and an overcurrent release expands the functionality of the circuit breaker
• Contact position indicator facilitates visual control of the circuit breaker status
• The ability to seal the lever prevents accidental change of the circuit breaker state
• "ON/OFF" marking on the switching lever increases user comfort
