Parameter Comparison

Engineering Selection Recommendations

Both the ABC-1-1/2-R and BK/ABC-1-1/2-R ceramic cartridge fuses are manufactured by Eaton - Electronics Division and maintain active product status with full CSA and UL certifications. The parts are ROHS3 compliant and carry identical electrical specifications, mechanical dimensions, and breaking capacities.

Selection between these part numbers is based on availability and inventory sourcing requirements. Both parts are suitable for direct substitution in applications requiring a 1.5 A, 250 V AC / 125 V DC fast-blow ceramic cartridge fuse in 3AB or 3AG holder configurations. The ABC-1-1/2-R designation maintains 786 pieces in current inventory, while the BK/ABC-1-1/2-R designation maintains 882 pieces in current inventory.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-1-1/2-R be used as a direct replacement for ABC-1-1/2-R?

A: Yes. The BK/ABC-1-1/2-R is a direct equivalent with identical electrical ratings (1.5 A, 250 V AC, 125 V DC), mechanical dimensions (0.250" Dia x 1.250" L), fuse type (ceramic cartridge), response time (fast blow), breaking capacity (100 A AC, 10 kA DC), and approval certifications (CSA, UL).

Q: What holder types are compatible with these fuses?

A: Both the ABC-1-1/2-R and BK/ABC-1-1/2-R fuses are designed for use in 3AB and 3AG holder configurations. The fuse dimensions of 0.250" diameter by 1.250" length conform to these standard holder specifications.

Q: Are there any compliance differences between the two part numbers?

A: No. Both parts maintain identical compliance status: ROHS3 compliant, CSA approved, and UL approved. Both are manufactured by Eaton - Electronics Division and carry active product status.

Q: What is the significance of the melting I²t value of 1.163?

A: The melting I²t value of 1.163 defines the thermal energy required to melt the fuse element. This parameter is identical for both part numbers and determines the fuse's response characteristics in fast-blow operation at 1.5 A.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. Both fuses are rated for 250 V AC and 125 V DC operation. The DC cold resistance of 0.131 Ohms is specified for DC circuit applications.

Q: What is the breaking capacity specification?

A: The breaking capacity is 100 A AC and 10 kA DC at rated voltage. This specification is identical for both part numbers and defines the maximum fault current the fuse can safely interrupt.
