Branch Circuit/Short Circuit Protection Requirements
The controller requires branch circuit protection. Branch circuit protection requirements must be in accordance with the latest addition of the National
Electrical Code, NEC/NFPA-70.
UL Recognized Component (JFHR2) semiconductor fuses with current ratings and maximum I 2 t ratings as specified below must be used in the
controller. Refer to the table below for the recommended fuse manufacturer and part number.

* Other UL Recognized Component (JFHR2) semiconductor fuses may be used in the controller provided that the voltage, ampere and I 2 t
ratings shown above are not exceeded.
● Rated armature voltage: 240V dc
NOTE Semiconductor fuses are acceptable as branch circuit short-circuit protection for the solid-state motor controllers only.
