A9N21231 SCHNEIDER ELECTRIC

The A9N21231 from Schneider Electric's ProDis DT40 Vigi K series is a residual current circuit breaker (RCCB) designed to provide comprehensive protection against electrical faults. This 4.5kA RCCB is configured with 3 poles and a neutral (3P+N), making it suitable for three-phase electrical systems. It features a C curve, indicating its suitability for circuits with moderate inrush currents, commonly found in residential and commercial applications. The device has a current rating of 32A, specifying the maximum current it can handle continuously without tripping. It is a type AC RCCB, which means it is designed to detect and respond to sinusoidal alternating current residual currents. The RCCB trips when a residual current of 300mA is detected, quickly disconnecting the circuit to prevent electrical shock and fire hazards. This device combines the functions of a circuit breaker and a residual current device, offering both overload and short-circuit protection as well as protection against earth leakage faults. The A9N21231 is essential for ensuring electrical safety in various installations, protecting people and equipment from dangerous electrical conditions. Its robust design and reliable performance make it a trusted choice for electrical protection.
