Across
- 3. effective value of an AC sine wave
- 5. electrical load that pulls a large amount of current when first energized
- 6. condition that occurs when 1 phase of a 3 phase system opens
- 9. current carrying capacity of an overcurrent protective device
- 13. overcurrent that exceeds the normal fullload current of a circuit by a factor many times greater than normal
- 14. can be classified as an overcurrent that exceeds the normal full load current of a circuit
- 16. Underwriters Laboratories has develop basic physical specifications and electrical performance requirements for fuses
- 17. the measure of the heat energy developed within a circuit during the fuse's clearing
Down
- 1. a device that will clear a short circuit in less than one half cycle
- 2. time between beginning of overcurrent and final opening of circuit
- 4. amount of time required to melt a fuse link during a specified overcurrent
- 7. fuse used to protect solid state devices
- 8. instantaneous value of peak current let through by a current limiting fuse
- 10. maximum value of system voltage in which a fuse can be used
- 11. fuse that opens on overloads and short circuits very quickly
- 12. maximum short circuit current that a circuit breaker or fuse can safely interrupt
- 15. the time from the instant the fuse link has melted until the overcurrent is interrupted
