Legrand 402066 4P 25A 100mA 400V RCCB (Residual Current Circuit Breaker)

Legrand 402066 4P 25A 100mA 400V RCCB (Residual Current Circuit Breaker)

The Legrand 402066 4P 25A 100mA 400V RCCB is a residual current protection device designed for three-phase electrical systems. With a rated current of 25A and a residual current sensitivity of 100mA, this device ensures safety for both users and electrical installations by preventing electric shocks and reducing the risk of fire caused by current leakage. Operating at up to 400V, it is suitable for both residential and industrial applications.

Key Features

• Rated current 25A: Provides stable power supply for medium-capacity electrical equipment, ensuring reliable operation under loads up to 25A.

• Residual current sensitivity 100mA: Detects and disconnects the power supply when significant leakage current occurs, reducing the risk of electrical fires.

• 4-pole design: Offers full protection for three-phase electrical systems, ideal for large-scale projects and industrial environments.

• Leakage detection: Enhances user safety by detecting and cutting off power immediately in the event of current leakage, preventing electric shock hazards.

• Easy installation: DIN rail mounting design for quick and convenient setup and system integration.
