Circuit breaker 25kA, In=125A, characteristic B. 3-pole. AZ-3-B125 174514

Reliable protection of electrical installations – Eaton AZ-3-B125 circuit breaker

This three-pole circuit breaker from Eaton's AZ series is a key element ensuring safety in every electrical installation. Designed to protect circuits against overload and short circuit, it offers high reliability and performance. Characteristic B makes it ideal for protecting circuits with devices with moderate inrush current, such as lighting or sockets.

This circuit breaker is distinguished by its high short-circuit breaking capacity – up to 25 kA – which guarantees an effective response in emergency situations and minimizes the risk of damage. The rated current of 125A allows for the protection of circuits with a higher load, and the rated voltage of 400V makes it a universal solution for many applications.

Features and application

The Eaton AZ-3-B125 circuit breaker is used in a wide range of electrical installations, both in residential and commercial buildings. It is perfect for protecting:

• Lighting

• Electrical sockets

• Distribution circuits

• Electrical devices with moderate inrush current

The circuit breaker design allows for mounting on a TH35 rail, and a width of 4.5 modules allows for efficient use of space in the switchgear cabinet. The IP20 degree of protection protects against accidental contact, and compliance with IEC 60947-2 standards guarantees safe use.

Additionally, this circuit breaker has railway approvals, which confirms its high quality and reliability in demanding conditions. The possibility of using additional equipment (e.g. auxiliary contacts) allows for expanding the functionality of the circuit breaker and adapting it to individual installation needs. Energy limitation class 3 provides adequate protection in the event of an electric arc.
