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

The ABB B427945 differential block is designed to ensure electrical protection against possible insulation failures and risks of electric shock 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 differential block is designed to simultaneously protect the phase and neutral conductors of an electrical circuit. The sensitivity of 0.3A AC means that the differential lock can detect even the smallest current leaks and quickly disconnect the power to ensure the safety of systems and people.

The compact dimensions of 2 modules make the differential lock suitable for installation in standard electrical panels, ensuring effective protection without taking up too much space. This device is essential to ensure compliance with electrical safety standards and protect electrical systems from short circuits and insulation faults.

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