Circuit breaker 25kA, In=125A, characteristic B. 2-pole. AZ-2-B125 174501

Overcurrent circuit breaker from the AZ series is a reliable protection for electrical installations, designed for both domestic and industrial applications. The 2-pole model with a rated current of 125A and B characteristic provides effective protection against overloads and short circuits. Its withstand current to short-circuit up to 25kA guarantees safety even in difficult operating conditions.

This circuit breaker is a solid solution for installers and users who value safety and long-term reliability. The compact design (width of 3 modules) facilitates mounting in distribution boards, and the installation depth of 75 mm allows for flexible adaptation to different spaces. Energy limitation class 3 and surge category 3 confirm high resistance to interference.

Application and functionality:

The AZ-2-B125 circuit breaker with B characteristic is ideal for protecting circuits with receivers with high inrush current, such as electric motors or transformers. The B characteristic allows for momentary exceeding of the rated current without unnecessary tripping, which minimizes the risk of downtime in device operation. Rated insulation voltage Ui at 440V and rated impulse withstand voltage Uimp 4kV ensure safe operation under various voltage conditions. Additionally, the possibility of mounting accessories expands the functionality of the circuit breaker, allowing it to be adapted to specific installation needs.

Constructional features and compliance with standards:

The circuit breaker meets the requirements of IEC 60947-2 and EN 60898 standards, which guarantees its compliance with applicable safety standards. The degree of protection IP20 provides protection against accidental contact, and the high quality of workmanship with materials resistant to mechanical and thermal damage ensures long-term operation. The rated short-circuit breaking capacity Icu is 15kA at 230V and 400V, which confirms its effectiveness in the event of a short circuit. Pollution degree 2 indicates the possibility of use in environments with a moderate level of pollution.
