The values in the table above are maximum allowable values to be used with the listed drives.

The maximum values are well above the drive rated input current. Most applications can

use much lower fuse/breaker values. A smaller value of 125% - 175% of rated input current

is recommended. This allows for temporary motor overloads without tripping the circuit

protection.

The SureServo2 drives have an SCCR rating of 5kA. For short circuit protection, choose a

current-limiting fuse that limits the let-through current (at your installation's available fault

current level) to less than 5,000 Amps. For SureServo2, ADC recommends Class CC or JHL High

Speed Class J current-limiting fuses.

Example:

The time-current chart for JHL drive-rated fuses shows that a 30A JHL fuse will allow 50A for

an extended period of time before blowing.

A smaller fuse/breaker rating also helps with SCCR. The 30A JHL fuse above has a peak

let-through of less than 2,500A when connected to 100,000A RMS available fault current. A

60A JHL would allow a 5,000A peak with the same available RMS fault current. Using a smaller

fuse is better for device protection and SCCR ratings.
