The Schneider Electric M9R81440 is a 4-pole residual current circuit breaker (RCCB) from the Multi9 GFP series, engineered for robust ground fault protection in industrial electrical systems. This unit is rated for 40A and features a 26mA sensitivity, making it effective in detecting leakage currents to prevent electrical hazards and equipment damage.

Technical details

• Series: Multi9 GFP
• Type: Residual Current Circuit Breaker (RCCB)
• Poles: 4
• Rated Current: 40A
• Sensitivity: 26mA
• Protection Class: A-SI type, indicating enhanced sensitivity to sinusoidal AC and pulsating DC residual currents, with a specific focus on detecting ground faults that may occur even when the fault current is not sinusoidal.
• Voltage Compatibility: Buyers should verify specific voltage ratings against the manufacturer's datasheet, as this information is not explicitly encoded in the provided part number.
• Breaking Capacity: Buyers should verify specific breaking capacity ratings against the manufacturer's datasheet.

Applications & compatibility

This RCCB is suitable for use in a wide range of industrial environments requiring reliable protection against earth leakage faults. It is commonly integrated into control panels for machinery, power distribution systems, and safety circuits in manufacturing facilities, particularly where sensitive detection of ground faults is critical for personnel safety and operational continuity.
