a. The test of 5A,10A,20A,50A,100A,200A,500A is only performed for the verification of operation, and is not performed for the magnitude of current greater than the lower limit of over-current instant current tripping range.
b. The test is carried out for the current with the lrn being equal to the lower limit of the over-current instantaneous tripping range for type C or D.
