Overcurrent circuit breaker 25kA, In=63A, characteristic B. 2-pole. AZ-2-B63 174498

Overcurrent circuit breaker – reliable protection for your installation

This two-pole overcurrent circuit breaker from Eaton's AZ series, with a rated current of 63A and B characteristic, is a key element of electrical protection in every circuit. It provides effective protection against overload and short circuit, protecting both devices and the electrical installation. Its short-circuit strength of up to 25kA guarantees safety even in difficult conditions.

Characteristics and application

The circuit breaker is characterized by a B characteristic, which means it reacts quickly to an increase in short-circuit current, but is more tolerant of short-term current surges during the start-up of devices with a motor (e.g. pumps, fans). This minimizes the risk of unnecessary tripping of the circuit. It is ideal for protecting lighting circuits, socket outlets and other loads with a characteristic resistive or slightly inductive load. A width of 3 modules makes it easy to install in standard distribution boards.

Key advantages and features

• High breaking capacity: 25kA at 400V and 230V provides effective protection even with high short-circuit currents.
• B characteristic: Optimal for circuits with devices with short-term inrush currents.
• Mounting on TH35 rail: Standard mounting simplifies installation and replacement.
• Protection class IP20: Protection against touching with fingers and solid objects larger than 12mm.
• Expandability: Compatibility with additional accessories allows the circuit breaker to be adapted to specific installation needs.
• Compliance with standards: Meets the requirements of IEC 60947-2 and EN 60898 standards, guaranteeing safety and reliability.
• Energy limitation class 3: Provides adequate protection in the event of an electric arc.
• Rated voltage 400V: Suitable for standard power grids.
• Rated impulse withstand voltage Uimp 4kV: Withstanding impulse voltages increases reliability in difficult conditions.

This circuit breaker is a solid solution for both professional installers and end-users looking for reliable protection for their electrical installation. Its durability and compliance with standards ensure long-term and safe operation.
