Legrand 402067 4P 40A 100mA 400V RCCB (Residual Current Circuit Breaker)

Legrand 402067 4P 40A 100mA 400V RCCB (Residual Current Circuit Breaker)

The Legrand 402067 4P 40A 100mA 400V RCCB is a residual current protection device, specifically designed for three-phase electrical systems. With a rated current of 40A and a residual current sensitivity of 100mA, this device ensures safety for both people and electrical systems, preventing the risk of electric shock and fire caused by current leakage. It operates at a maximum voltage of 400V, suitable for both residential and industrial applications.

Key Features

• Rated current 40A: Supports a stable power supply for high-power devices, ensuring continuous operation without overload.

• Residual current sensitivity 100mA: Detects and quickly interrupts the circuit when significant leakage occurs, reducing the risk of fire or electric shock.

• 4-pole design: Provides comprehensive protection for three-phase systems, commonly used in large projects or industrial installations.

• Leakage detection: Ensures user safety by quickly detecting and disconnecting in case of leakage, preventing electric shock.

• Easy installation: DIN rail mounting allows convenient integration into electrical systems.
