Key Parameters

Substitute Part Grouping Explanation

Substitution of the NH00CG100 is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 100A
• Voltage Rating - AC: 500 VAC
• Fuse Class: NH
• Fuse Type: Square
• Mounting Type: Requires Holder
• Package / Case: Rectangular, Blade

The substitute part 100NH0G-B meets these core requirements. While dimensional variations exist between the main part and substitute, both conform to the NH class specification and rectangular blade package standard, ensuring mechanical and electrical compatibility within holder assemblies designed for this fuse class.

Parameter Comparison

Engineering Selection Recommendations

The 100NH0G-B from Eaton - Bussmann Electrical Division is the designated manufacturer-recommended substitute for the obsolete NH00CG100. Both components share identical current and AC voltage ratings, NH class designation, and square fuse type with rectangular blade packaging.

The 100NH0G-B maintains active product status, ensuring continued availability and supply chain reliability. This substitute carries ROHS3 compliance and holds multiple international approvals including CEBEC, FEMKO, KEMA, L.R.S, NEMKO, and VDE, compared to the VDE approval of the original part.

Selection of the 100NH0G-B is appropriate for applications requiring 100A protection at 500 VAC within NH class fuse holder assemblies. The substitute maintains the indicating feature and fast-blow response characteristics necessary for motor protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 100NH0G-B be used as a direct replacement for the NH00CG100?

A: Yes. Both components meet the core electrical requirements: 100A current rating, 500 VAC voltage rating, NH class designation, and square fuse type with rectangular blade packaging. Both are designed for use in NH class fuse holders.

Q: What is the significance of the NH class designation?

A: NH class fuses are standardized industrial fuses with defined electrical and mechanical characteristics. Both the NH00CG100 and 100NH0G-B conform to this class, ensuring compatibility with standard NH fuse holder assemblies.

Q: Does the dimensional difference between the two parts affect compatibility?

A: Both parts conform to the rectangular blade package standard for NH class fuses. Dimensional variations within this class do not prevent mechanical and electrical compatibility in standard NH fuse holders.

Q: What is the difference in RoHS compliance between these parts?

A: The NH00CG100 is RoHS non-compliant, while the 100NH0G-B is ROHS3 compliant. For applications subject to RoHS regulations, the 100NH0G-B is the appropriate selection.

Q: Are there differences in international approvals?

A: The 100NH0G-B carries broader international approvals (CEBEC, FEMKO, KEMA, L.R.S, NEMKO, VDE) compared to the NH00CG100 (VDE only). This provides greater flexibility for global applications.

Q: What is the indicating feature?

A: Both components include an indicating function, which provides visual confirmation of fuse operation status.
