Class J Current Limiting High Speed Fuse, 600VAC, 1-1/8 x 4-5/8 inches
Main branch fusing protects your personnel, equipment, and temperature control enclosure from over-current conditions caused by heater short circuits, electrical supply over-voltage events, and other fault conditions.
Electrical code requires heater current protection to be sized 125% of the full load current and not to exceed the current ratings of the individual components or wiring. The power controller manufacture recommends not exceeding 165% of the full load current. Do not exceed the maximum fuse size listed in the temperature control panel specifications.
