A9P52740 SCHNEIDER ELECTRIC

The Acti9 iC40 A9P52740 is a miniature circuit breaker (MCB) from Schneider Electric designed for reliable circuit protection in various applications. This particular model is a 3P+N (three-pole plus neutral) circuit breaker, making it suitable for three-phase electrical systems with a neutral conductor. It has a current rating of 40A, indicating the maximum current it can handle continuously without tripping. The iC40 A9P52740 features a C curve tripping characteristic, which means it's designed to trip relatively quickly under moderate overloads, making it suitable for protecting circuits with inductive loads like motors and transformers. It offers a breaking capacity of 4500A according to IEC 60898 and 6kA according to IEC 60947-2, indicating its ability to safely interrupt fault currents up to these levels. This MCB provides protection against short circuits and overloads, preventing damage to equipment and ensuring safety. The Acti9 range is known for its high performance, reliability, and safety features. It is commonly used in residential, commercial, and industrial electrical distribution systems. Its compact design allows for easy installation in distribution boards and enclosures. The A9P52740 contributes to the overall safety and efficiency of electrical installations.
