Abb b427945 differential block 4 poles max 25a 0.3a ac 2 modules

The ABB B427945 RCD block is designed to provide electrical protection against insulation faults and electric shock hazards in industrial or commercial electrical systems. Here are the main specifications of this device:

• Number of poles: 4 poles
• Rated capacity: maximum 25A
• Sensitivity: 0.3A AC
• Dimensions: 2 modules

The RCD is designed to simultaneously protect the phase and neutral conductors of an electrical circuit. Its sensitivity of 0.3A AC means it can detect even the smallest current leaks and quickly disconnect the power supply to ensure the safety of both the system and people.

The compact size of 2 modules makes the RCD block suitable for installation in standard electrical panels, ensuring effective protection without taking up too much space. This device is essential for ensuring compliance with electrical safety standards and protecting electrical systems from short circuits and insulation faults.

The ABB B427945 differential block represents a reliable solution for electrical protection in industrial and commercial environments, offering effective protection against electrical hazards.
