Bibliography

This guide for low-voltage fuses shows how current-limiting fuses are easy to apply to protect today's complex and sensitive electronic equipment. It specifically covers low-voltage fuses up to a.c. 1 000 V and d.c. 1 500 V. Provides information on the application of fuses which are not always covered, as well as important facts which are sometimes difficult to locate in standards.
