ABB Control. • The actual power dissipation the fuse the load current shall lower than the maximum allowed power dissipations given table below.PowerLine Switch fuses for the protection power semiconductors Technical information When the Fuse and Switch Fuse are selected, the following shall evaluated: • The operational current shall lower than the maximum ratings the switch fuse, see the table below. allowed cut-off current, peak value (refer single phase fuse tests) Rated conditional short-circuit current r. The power dissipation 0,44 77W= W.5W 63A 7. The value must lower than the value given for the switch fuse, see the table below.5W suitable fuse sizes OS 160R_ For all 160A 12W 160A 10W suitable fuse 135A 12W sizes OESA 250R_ 00 250A 42W 250A 30W 0 (1*) 250A 41W 250A 31W 1 250A 40W 250A 25W OESA 400R_ 1 400A 42W 400A 32W 2 400A 35W 400A 25W OESA 630R_ 1 and 500A 60W 500A 50W 600A 50W 600A 37W 3 500A 50W 450A 37W 600A 37W 600A 27W OESA 800R_ 2 700A 60W 620A 45W 720A 50W 720A 35W 3 680A 55W 610A 42W 720A 46W 720A 30W Max. From the curve P/Pn=f(I/In) given the fuse manufacturer, the ratio P/Pn thus determined, and this example 0,44. 80 kA, 415V 100 kA, 500V kA, 690V OS 32R_ 7.5W 32A 3.

The actual power dissipation the fuse determined: The ratio between the operational current and the rated current of the fuse 380 550 0,69. The required fuse can be used with switch fuse OESA 400R_. See also the operational ratings, the table the next page.5W suitable fuse sizes OS 63R_ For all 63A 7.m. • The cut-off current the fuse actual prospective current should checked. From the table for OESA 400R_ maximum ratings seen that the operational current (380A) well the fuse power dissipation (34 are lower than the max.s. ratings
