Overcurrent circuit breaker 25kA, In=63A, B characteristic. 3+N pole. AZ-3N-B63 174524

25kA Overcurrent Circuit Breaker – Reliable Protection for Electrical Installations

This three-pole circuit breaker with an additional neutral pole (3+N) is a key element of any safe electrical installation. Designed to protect circuits from overload and short circuit, it ensures stable operation and long-term reliability. The rated short-circuit breaking capacity of 25kA guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

The circuit breaker is characterized by a B characteristic, which means it is ideal for protecting circuits with receivers with moderate inrush current – such as lighting, sockets, and household appliances. At the same time, the disconnectable N pole increases safety, allowing for complete disconnection of the circuit in the event of a failure. A width of 6 modules simplifies installation in standard distribution boards.

Construction features and application

The AZ-3N-B63 circuit breaker is made of high-quality materials, which translates into its durability and resistance to environmental conditions. The IP20 degree of protection provides protection against accidental contact. The rated insulation voltage Ui of 440V and the rated impulse withstand voltage Uimp 4kV confirm its high quality and compliance with safety standards.

Application:

• Electrical installations in residential and commercial buildings
• Main and sub-distribution boards
• Protection of lighting and socket circuits
• Powering electrical appliances with moderate inrush current
• Approved for railway applications (according to manufacturer's information)
