Chint Earth Leakage add-on Block NB1L-63 63A 300MA Type AC 4P 3.5 Modules 198433

Earth Leakage add-on Blocks are mechanically designed to prevent mismating between the block and the circuit breaker: the rating of the block must always be equal to or greater than that of the circuit breaker. The plastic clamp on the side allows faster mounting of the block on the circuit breaker, and a push-button prevents possible tripping.

 

It is used to protect human health in the event of a ground fault (electrical leakage) or phase-to-ground electrocution, thus also providing protection against macro electrical shock, both direct and indirect, on exposed persons.

 

The AC-type Earth Leakage add-on Block, works only with alternating current. Almost all installations for civil use fall into this type.
