Circuit breaker 25kA, In=63A, characteristic B. 3-pole. AZ-3-B63 174511

Overcurrent switch – reliable installation protection

This three-pole overcurrent switch from Eaton's AZ series is a key element of every safe and efficient electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. Designed for both domestic and industrial applications, it offers high reliability and easy installation.

Characteristics and application

The switch is characterized by a rated current of 63A and a B characteristic, which means it is ideal for protecting circuits with devices with moderate inrush currents – such as lighting, sockets or small motors. The rated short-circuit breaking capacity of 25kA (at 400V) guarantees safe disconnection of the circuit in the event of a serious short circuit. Energy limitation class 3 ensures a quick response and minimizes the effects of failure.

The switch is easy to install thanks to its standard width of 4.5 modules and an installation depth of 75 mm. Protection class IP20 protects against touching with fingers and solid objects larger than 12mm. The possibility of additional equipment allows the switch to be adapted to specific installation needs.

Key advantages and benefits

• High short-circuit breaking capacity (25kA): Ensures safety even in installations exposed to high short-circuit currents.
• B characteristic: Ideal for protecting circuits with devices with moderate inrush currents, preventing unnecessary tripping during short-term overloads.
• Energy limitation class 3: Guarantees a quick response to a short circuit, minimizing damage to the installation and connected devices.
• Three-pole design (3P): Provides complete protection for three-phase electrical circuits.
• Expandability: Compatibility with additional accessories allows you to adapt the switch's functionality to individual needs.
• Renowned manufacturer (Eaton): Guarantee of high quality, reliability and long product life.
• Compliance with standards: Meets the requirements of IEC 60947-2 and EN 60898 standards, ensuring safe use.

The Eaton AZ-3-B63 switch is an investment in safety and peace of mind – for both professional installers and end users. Its solid construction, high quality workmanship and compliance with applicable standards make it a reliable element of every modern electrical installation.
