A9N21015 SCHNEIDER ELECTRIC

The A9N21015 from Schneider Electric is a DT40 series miniature circuit breaker (MCB) designed for reliable circuit protection. This MCB features a 1P+N (one pole plus neutral) configuration, making it suitable for single-phase applications where both phase and neutral conductors need protection. It has a rated current of 40A, indicating its capacity to handle circuits with a maximum current demand of 40 amperes. The B curve tripping characteristic signifies its sensitivity to overloads and short circuits, providing faster tripping for resistive loads and applications with low inrush currents. This MCB is ideal for residential, commercial, and industrial applications, offering protection against overcurrents and short circuits. It helps prevent damage to electrical equipment and reduces the risk of electrical fires. The DT40 series is known for its compact design, ease of installation, and compliance with international standards, ensuring safety and reliability. Its robust construction and high-quality materials guarantee a long service life and consistent performance. This MCB provides a dependable solution for safeguarding electrical circuits and equipment.
