ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC A9R21240 - Residual Current Circuit Breaker (RCCB)
The SCHNEIDER ELECTRIC A9R21240 is a 2-pole Residual Current Circuit Breaker from the Acti 9 iID series, engineered for earth leakage protection in low-voltage electrical distribution systems. This device provides protection against indirect contact and fire hazards by detecting and interrupting sinusoidal alternating residual currents. It is suitable for integration into commercial, industrial, and residential electrical panels requiring compliance with IEC 61008-1 standards.
