AG35 Fuse - Equivalent & Substitute Parts Reference

Part Overview

The AG35 is a Class G cartridge fuse manufactured by Mersen USA Newburyport-MA L.L.C., rated for 35 amperes at 480 volts AC with a breaking capacity of 100kA. This fuse is designed for industrial electrical applications requiring reliable overcurrent protection in medium-voltage circuits. The part maintains Active product status with full ROHS3 compliance and has 711 units in current stock inventory.

Substitute parts become necessary when the primary AG35 is unavailable, when alternative sourcing reduces lead times, or when system design requires evaluation of equivalent protection devices from different manufacturers while maintaining identical electrical and mechanical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AG35 is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 35 amperes (exact match required)
• Voltage Rating - AC: 480 volts (exact match required)
• Breaking Capacity: 100kA at rated voltage (exact match required)
• Fuse Class: G (exact match required)
• Fuse Type: Cartridge (exact match required)
• Product Status: Active (ensures ongoing availability and support)
• RoHS Compliance: ROHS3 or equivalent (ensures regulatory alignment)

The two substitute parts identified—0SLC035.T (Littelfuse Inc.) and SC-35 (Eaton - Bussmann Electrical Division)—meet all mandatory electrical parameters. Both are Class G cartridge fuses rated 35A at 480VAC with 100kA breaking capacity. Physical dimensions remain within acceptable tolerance ranges for standard cartridge fuse holders. Both manufacturers maintain Active product status with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AG35, 0SLC035.T, and SC-35—maintain Active product status with current manufacturing and inventory support. Selection between these equivalents is based on the following engineering criteria:

AG35 (Mersen): Primary choice when Mersen sourcing is preferred or contractually specified. Maintains full ROHS3 compliance and 100kA breaking capacity at 480VAC.

0SLC035.T (Littelfuse POWR-GARD® SLC): Suitable substitute with Medium Blow response time, 170VDC rating, and comprehensive approval certifications (CE, CSA, QPL, UL). Dimensions 0.406" Dia x 2.252" L are compatible with standard cartridge fuse holders.

SC-35 (Eaton - Bussmann SC Series): Suitable substitute with Slow Blow response time, 300VDC rating, and ceramic construction. Dimensions 0.410" Dia x 2.250" L are compatible with standard cartridge fuse holders. RoHS compliant with CE, CSA, and UL certifications.

All three parts satisfy the mandatory electrical parameters for Class G, 35A, 480VAC, 100kA breaking capacity applications. Selection should account for response time characteristics (Medium Blow vs. Slow Blow) and DC voltage requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can 0SLC035.T and SC-35 be used interchangeably with AG35?

A: Yes, both substitute parts meet the mandatory electrical specifications: 35A current rating, 480VAC voltage rating, 100kA breaking capacity, and Class G fuse classification. All three are cartridge fuses compatible with standard holders. Physical dimensions are within acceptable tolerance ranges (diameter 0.406" to 0.410", length 2.250" to 2.252").

Q: What is the difference between Medium Blow and Slow Blow response times?

A: Response time is not specified for the AG35. The 0SLC035.T features Medium Blow response, while the SC-35 features Slow Blow response. These characteristics affect how quickly the fuse element melts under overcurrent conditions. Application-specific circuit requirements determine which response time is appropriate.

Q: Are there DC voltage rating differences I should consider?

A: The AG35 does not specify a DC voltage rating. The 0SLC035.T is rated 170VDC, and the SC-35 is rated 300VDC. For AC-only applications at 480VAC, all three parts are equivalent. For circuits requiring DC protection, verify that the selected fuse's DC rating matches the application requirements.

Q: Do all three parts meet the same compliance standards?

A: All three parts are ROHS3 or RoHS compliant. The 0SLC035.T carries CE, CSA, QPL, and UL certifications. The SC-35 carries CE, CSA, and UL certifications. For applications requiring specific approval agencies, verify that the selected substitute meets contractual or regulatory requirements.

Q: Are the physical dimensions compatible with my existing fuse holder?

A: Standard Class G cartridge fuse holders accommodate the dimensional ranges provided. AG35 dimensions are not specified in the available data. The 0SLC035.T measures 0.406" Dia x 2.252" L, and the SC-35 measures 0.410" Dia x 2.250" L. Both are within standard cartridge fuse tolerances. Verify holder specifications if non-standard equipment is in use.

Q: What packaging considerations apply to these substitutes?

A: The AG35 is supplied in Box packaging. Both 0SLC035.T and SC-35 are supplied in Bulk packaging. Verify that bulk packaging meets procurement and inventory management requirements for your application.
