Legrand 411190 DX3 RCBO 4P C40A 30mA Type AC

The Legrand 411190 DX³ is a 4P residual current circuit breaker with overcurrent protection (RCBO) rated C40A with 30mA sensitivity, Type AC. It provides combined overload, short-circuit, and earth fault protection for three-phase circuits in a single DIN rail device.

Technical specifications:

• Part number: 411190
• Manufacturer: Legrand
• Series: DX³
• Type: RCBO (combined MCB and RCD)
• Poles: 4P
• Rated current: 40A
• Curve: C

• RCD type: AC
• Mounting: DIN rail
• Standards: IEC/EN 61009-1

Features and benefits:

• 4P combined RCBO protects all three phases and neutral simultaneously
• C curve suits circuits with moderate inrush currents
• Saves panel space versus separate 4P MCB and 4P RCCB

Applications:

• Three-phase circuit protection with earth fault detection
• Motor and equipment circuits requiring combined overcurrent and earth fault protection

Compliant with IEC/EN 61009-1.
