Substitute Part Grouping Explanation

Substitution eligibility for the GMT-10A is determined by strict equivalence across the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating - AC: 125 VAC (exact match required)
• Voltage Rating - DC: 60 VDC (exact match required)
• Response Time: Fast Blow (exact match required)
• Fuse Type: Indicating Fuse (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Breaking Capacity: 300A AC, 450A DC (exact match required)
• Physical Dimensions: 0.688" L x 0.127" W x 0.810" H (exact match required)

The substitute part BK/GMT-10A meets all electrical and mechanical parameters specified for the GMT-10A, confirming direct interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both GMT-10A and BK/GMT-10A are active products from Eaton - Bussmann Electrical Division with identical electrical specifications and physical dimensions. Selection between these parts may be based on inventory availability: GMT-10A has 1052 units in stock, while BK/GMT-10A has 16646 units available. Both parts carry UR approval and maintain RoHS compliance (GMT-10A: RoHS Compliant; BK/GMT-10A: ROHS3 Compliant). The BK/GMT-10A additionally carries REACH Unaffected status. No technical differentiation exists between these parts for circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can BK/GMT-10A be used as a direct replacement for GMT-10A?

A: Yes. Both parts are identical in current rating (10A), voltage ratings (125 VAC / 60 VDC), response time (Fast Blow), fuse type (Indicating), mounting requirements (Requires Holder), breaking capacity (300A AC, 450A DC), and physical dimensions (0.688" L x 0.127" W x 0.810" H). Direct substitution is supported.

Q: What determines if a fuse can substitute for the GMT-10A?

A: A substitute fuse must match all of the following: 10A current rating, 125 VAC / 60 VDC voltage ratings, Fast Blow response, Indicating fuse type, Requires Holder mounting, 300A AC / 450A DC breaking capacity, and 0.688" L x 0.127" W x 0.810" H dimensions.

Q: Are there compliance differences between GMT-10A and BK/GMT-10A?

A: Both parts are UR approved and RoHS compliant. BK/GMT-10A carries additional REACH Unaffected certification. Both are classified as EAR99 for export control purposes.

Q: Does the fuse require a specific holder type?

A: Yes, both GMT-10A and BK/GMT-10A require a fuse holder for installation. The physical dimensions (0.688" L x 0.127" W x 0.810" H) must be matched to the holder specifications.

Q: What is the indicating feature on this fuse?

A: The indicating feature provides visual fault notification when the fuse operates. This allows operators to identify circuit protection events without requiring electrical testing equipment.
