With reference to the picture below:
The first block connector have a 3A shown beside, the second one with 5A and the third one have 10A.
What do the 3A, 5A and 10A mean?
Does it mean that the 3A can support a maximum of 3A current? Does the 5A support maximum of 5A current and a minimum of 3A current?
Best Answer
Those ratings indicate that the smallest terminal block can safely carry up to 3 Amps on each terminal, the middle one can handle up to 5 Amps, and the largest, up to 10 Amps.
The terminals will over-heat if they are asked to carry more than the rated current.
