A9P42725 SCHNEIDER ELECTRIC

The Acti9 iC40 A9P42725 is a miniature circuit breaker (MCB) from Schneider Electric, designed for reliable circuit protection in various applications. This particular model features a 3P+N (three-pole plus neutral) configuration, making it suitable for three-phase electrical systems with a neutral conductor. It has a current rating of 25A, indicating the maximum current it can handle continuously without tripping. The B curve tripping characteristic signifies its sensitivity to overloads and short circuits, tripping faster than a C curve MCB but slower than an A curve. It offers a breaking capacity of 4500A according to IEC 60898 and 6kA according to IEC 60947-2, ensuring it can safely interrupt fault currents up to these levels. The Acti9 iC40 series is known for its robust design, providing enhanced safety and reliability. It is commonly used in residential, commercial, and industrial settings to protect electrical circuits from damage caused by overcurrents and short circuits. Its compact size allows for easy installation in distribution boards and consumer units. This MCB contributes to the overall safety and efficiency of electrical installations.
