Key Specifications

The A9Z11440 comes with important specifications that define its operation and suitability for various applications:

• Inom (Nominal Current): 40A
• Ires (Residual Operating Current): 30mA
• Poles: 4
• Voltage Rating: 400VAC
• Ingress Protection Rating: IP20
• Wiring Capacity: 1÷25mm²

Understanding the Features of the A9Z11440

1. Protection Against Electrical Faults

The primary function of the A9Z11440 RCD breaker is to provide protection against earth faults. When it detects a fault current that exceeds the 30mA residual operating current threshold, it automatically cuts off the electrical supply. This rapid response helps prevent potential hazards, including electrical shocks and fires.

2. 4-Pole Design

With 4 poles, the A9Z11440 is well-suited for three-phase systems with a neutral. This configuration allows for a balanced load distribution and helps manage multiple circuits effectively. The versatility of having 4 poles makes it suitable for both residential and industrial applications.

3. High Ingress Protection (IP20)

The A9Z11440 has an IP20 rating, which ensures adequate protection against dust and accidental contact with live parts. This feature enhances the safety and reliability of the breaker when installed in various environments. However, it is important to note that the IP20 rating indicates that it is not suitable for outdoor installation without additional protection.

4. Wide Wiring Capacity

Another standout feature of the A9Z11440 is its versatile wiring capacity, accommodating wire sizes ranging from 1mm² to 25mm². This flexibility makes it convenient for use in different electrical installations, allowing it to work with various wire sizes to meet specific needs.
