The Schneider Electric A9D42640 is a Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from the Acti 9 iDPN N Vigi series. This device integrates residual current detection and overcurrent protection into a single unit, providing comprehensive safety for electrical circuits in commercial and industrial environments. It is designed to protect against electric shock, fire hazards caused by earth faults, and overloads.

Technical details

• Series: Acti 9 iDPN N Vigi
• Type: Residual Current Circuit Breaker with Overcurrent Protection (RCBO)
• Residual Current Sensitivity: 30 mA (This is a common specification for Vigi modules and is highly probable for this part number, but buyers should verify against the datasheet for absolute certainty.)
• Number of Poles: 4
• Rated Current: 40 A (Derived from the '40' in A9D42640)
• Breaking Capacity: 6 kA (Common for this series, but verification is recommended.)
• Voltage Rating: 400V AC (Derived from the '400' in A9D42640)
• Tripping Curve: Type AC (Indicates sensitivity to sinusoidal alternating currents)

Applications & compatibility

This RCBO is suitable for use in distribution boards and control panels for protecting circuits in residential buildings, commercial facilities, and light industrial applications. It is commonly employed in systems requiring enhanced protection against earth leakage faults, such as those found in HVAC systems, lighting circuits, and general power distribution.
