This selection table has been based upon the following criteria: 1. Withstand against magnetizing inrush current taken as 12 times full-load current for 0.1 second. 2. Withstand against 150% permissible overload current. Recommendations marked with asterisks have the following significance:*Limited to permissible overloads of 130%. **Permits use of a 12kV OHFMA 80A fuse with a 100kVA transformer where permissible overload does not exceed 130%. 3. For 6.6kV systems, 12kV fuse links are recommended where possible in the interests of standardization. 4. Wherever possible, 10 inch long FO1 fuse links are offered rather than equivalent 14 inch FO2 types. 5. The above recommendations are not generally applicable to transformers feeding motor circuits with starting currents in excess of the transformer full load current. In this event, please consult Bussmann.

Medium Voltage Fuses and Fuse Links
Medium Voltage Fuse Links High-Surge Type H Fuse Links High-surge, Type H fuse links are manufactured in ratings of 1, 2, 3, and 5 amperes. They have been developed principally for primary fusing of small-sized transformers. Type H links are manufactured in the universal buttonhead design. Type N Fuse Links Type N fuse links conform to previous NEMA standards and have been superseded by Type K and T links. Type N fuse links are manufactured in the universal button design in ratings of 5 through 200 amperes for use in NEMA standard dimensioned cutouts rated through 27 kv.
EEI-NEMA Type K and T Fuse Links These fuse links afford effective overcurrent protection to systems and equipment. In addition to apparatus protection, they can be coordinated with other overcurrent protective devices for sectionalizing in order to isolate feeder branches.

This selection table has been based upon the following criteria: 1. Withstand against magnetizing inrush current taken as 12 times full-load current for 0.1 second. 2. Withstand against 150% permissible overload current. Recommendations marked with asterisks have the following significance:*Limited to permissible overloads of 130%. **Permits use of a 12kV OHFMA 80A fuse with a 100kVA transformer where permissible overload does not exceed 130%. 3. For 6.6kV systems, 12kV fuse links are recommended where possible in the interests of standardization. 4. Wherever possible, 10 inch long FO1 fuse links are offered rather than equivalent 14 inch FO2 types. 5. The above recommendations are not generally applicable to transformers feeding motor circuits with starting currents in excess of the transformer full load current. In this event, please consult Bussmann.

Medium Voltage Fuses and Fuse Links
Medium Voltage Fuse Links High-Surge Type H Fuse Links High-surge, Type H fuse links are manufactured in ratings of 1, 2, 3, and 5 amperes. They have been developed principally for primary fusing of small-sized transformers. Type H links are manufactured in the universal buttonhead design. Type N Fuse Links Type N fuse links conform to previous NEMA standards and have been superseded by Type K and T links. Type N fuse links are manufactured in the universal button design in ratings of 5 through 200 amperes for use in NEMA standard dimensioned cutouts rated through 27 kv.
EEI-NEMA Type K and T Fuse Links These fuse links afford effective overcurrent protection to systems and equipment. In addition to apparatus protection, they can be coordinated with other overcurrent protective devices for sectionalizing in order to isolate feeder branches.
