Circuit breaker 25kA, In=100A, characteristic B. 1-pole. AZ-B100 174487

Single-pole circuit breaker from the AZ series, designed to protect electrical installations against overloads and short circuits. It features a high short-circuit breaking capacity – up to 25kA – making it a reliable safety element in demanding applications. The AZ-B100 model with characteristic B provides a quick response to short-circuit currents while tolerating short-term current surges typical of starting motors and other inductive devices.

This circuit breaker is a solid solution for both professional installers and end-users looking for safe and effective protection of electrical circuits. Its compact size (1 module width) simplifies installation in distribution boards, and the high quality of workmanship guarantees long-lasting and trouble-free operation. The use of characteristic B makes it particularly recommended for protecting lighting circuits and sockets in public places.

• High short-circuit breaking capacity (25kA): ensures effective protection of the installation even in the event of serious failures.
• Characteristic B: ideal for protecting circuits with devices with high inrush current (e.g., motors, transformers). Allows for momentary exceeding of the rated current without unnecessary tripping.
• Compact dimensions (1 module): facilitate installation in tight distribution boards.
• Compliance with standards: ensures safety and reliable operation.
• Expandability: compatible with a wide range of auxiliary accessories, allowing you to customize functionality to individual needs.
• Rated voltage 400V: universal application in three-phase and single-phase installations.

This circuit breaker meets the requirements of overvoltage category III and energy limitation class 3, confirming its high resistance to interference and ability to protect against the effects of overvoltage. The IP20 degree of protection provides protection against accidental contact, and the solid construction guarantees durability even in harsh operating conditions. Mounting is on a TH35 rail, which is standard in most modular distribution boards.
