The Schneider Electric A9N17521 is a 1-pole + neutral miniature circuit breaker from the iDPN series, engineered for robust protection of electrical circuits. This device is specifically designed to safeguard against overcurrent conditions, including both overloads and short circuits, making it suitable for demanding industrial environments and installations with significant capacitive loads.

Technical Details

• Series: iDPN
• Configuration: 1 Pole + Neutral (1P+N)
• Rated Current: 25A
• Tripping Curve: B Curve
• Application: Protection against overloads and short circuits
• Inrush Current Tolerance: High, suitable for loads with significant starting currents
• Voltage Rating: Verify with manufacturer datasheet for specific voltage class (e.g., 230/400V AC)
• Interrupting Capacity: Verify with manufacturer datasheet for specific breaking capacity (e.g., 6kA)

Applications & Compatibility

This Schneider Electric circuit breaker is commonly deployed in control panels for machinery, power distribution systems in manufacturing facilities, and building automation systems. Its B tripping curve makes it particularly effective in applications such as motor protection where high inrush currents are expected during startup, or in lighting circuits with fluorescent ballasts.
