Circuit breaker 25kA, In=100A, characteristic B. 2-pole. AZ-2-B100 174500

Robust protection for electrical installations – Eaton AZ-2-B100 circuit breaker

This two-pole circuit breaker from Eaton’s AZ series provides reliable protection for your electrical installation. Designed to operate at 400V and with a rated current of 100A, it effectively protects circuits against overloads and short circuits. The B characteristic ensures a quick response to current increases, which is particularly important for inductive and capacitive loads. This circuit breaker is distinguished by its high short-circuit breaking capacity – up to 25kA, guaranteeing safety even in difficult conditions.

Features and applications

The AZ-2-B100 circuit breaker is ideal for both domestic and industrial applications. Its compact design (3 modules wide) makes it easy to install in standard distribution boards. The ability to connect wires with a cross-section from 2.5 mm² to 50 mm² provides flexibility in selecting the appropriate cables. The device meets high safety standards (energy limitation class 3, overvoltage category 3, protection degree IP20) and is designed to operate in temperatures from -25°C to +55°C. Additionally, the circuit breaker can be expanded with auxiliary accessories, increasing its functionality.

• High short-circuit breaking capacity (25kA): Ensures effective protection of the installation even with high short-circuit currents.
• B characteristic: Ideal for protecting circuits with inductive and capacitive loads, such as motors and transformers. Reacts quickly to current increases, minimizing the risk of damage.
• 3 modules wide: Compact dimensions make it easy to install in tight distribution boards.
• Wire cross-section 2.5 - 50 mm²: Allows connection of wires of different thicknesses, adapting to the needs of the installation.
• Expandability: Additional accessories allow you to adapt the functionality of the circuit breaker to specific application requirements.
• Compliance with standards: The device meets stringent safety standards, ensuring reliable protection of the electrical installation.
