Overcurrent circuit breaker 25kA, In=20A, characteristic D. 3-pole. AZ-3-D20 174515

Solid protection of electrical installations with Eaton AZ-3-D20 circuit breaker

This three-pole circuit breaker from the AZ series, with a rated current of 20A and characteristic D, provides reliable protection for your electrical installation. Designed by the renowned Eaton Electric, it effectively protects against the effects of overloads and short circuits. The rated short-circuit breaking capacity of 25kA guarantees safety even in the event of serious disturbances.

This circuit breaker is suitable for both domestic and industrial installations, and its versatility will be appreciated by both professional installers and end-users. Characteristic D makes it particularly recommended for circuits with devices with high inrush currents – motors, transformers or switch-mode power supplies. This will avoid unnecessary tripping of the circuit when starting these devices.

Construction features and operating parameters

The AZ-3-D20 circuit breaker is made of high-quality materials, which translates into its durability and reliability. Mounting is done on a TH35 rail, and a width of 4.5 modules allows for efficient use of space in the switchgear cabinet. The IP20 degree of protection provides protection against accidental contact, and limitation class 3 and overvoltage category III guarantee safety in difficult operating conditions. The cross-section of conductors from 2.5 to 50 mm² gives great freedom in choosing the appropriate cables.

The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is 4kV. The circuit breaker operates in the frequency range of 50-60Hz and is adapted to work in an ambient temperature from -25°C to +55°C. Additionally, the possibility of mounting accessories expands the functionality of the device and allows it to be adapted to individual needs. Compliance with IEC 60947-2 standards ensures a high level of safety and reliability.
