Power fuses are like overdraft protection on checking accounts., and in this case, power equipment is the bank. Power overloads are like bouncing a check, and fuses respond to overdraws accordingly, protecting the system and keeping it balanced. In the illustration below, you can see how a current limiting fuse provides “overdraft” protection for power equipment.
Select Steps 1 – 4 of this diagram to see how melting in a Helix Current Limiting Fuse absorbs heat and extinguishes an arcing electrical current.
Read the full original article on Current Limiting Fuse protection.
Key considerations for choosing the right fuse:
Voltage rating: Maximum ac or dc voltage at which fuse is designed to operate.
Interrupting Rating: The highest alternating or direct current fuse is designed to interrupt under specified application.
Continuous Current Rating: Rating fuse can continuously carry current without exceeding temperature rise values.
Coordination: The fuse must be in ‘coordination” with the equipment line and load to ensure melting (overcurrent and arcing time) and clearing (fuse opening time).
