Tripping characteristics

Example:

Correction factor (k) = I non-tripping

Impulse length

Example: Non-tripping current (Electromagnetic release)

S 201-B16
I non-tripping = k x non-tripping current B-Characteristic = 3 x I n
I non-tripping = 4,2 x 3 x 16 C-Characteristic = 5 x I n
I non-tripping = 201,6 A D-Characteristic = 10 x I n
K-Characteristic = 10 x I
n
Z-Characteristic = 2 x I
n
The S 201-B16 does not trip at an impulse of 600 es at a current up to 201,6 A.
