Equivalent & Substitute Parts for 0SLC030.T

Part Overview

The 0SLC030.T is a cartridge fuse manufactured by Littelfuse Inc. under the POWR-GARD® SLC series. This component is rated for 30A at 480 VAC / 170 VDC and is designed for electrical and industrial applications requiring medium-blow response characteristics. The part is currently active in production with 879 units in stock. Substitute parts are identified when equivalent electrical ratings and mechanical compatibility are maintained within the cartridge fuse category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0SLC030.T is determined by the following critical parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating - AC: 480 VAC (exact match required)
• Voltage Rating - DC: Minimum 170 VDC (equal or higher acceptable)
• Fuse Type: Cartridge (mechanical compatibility)
• Package / Case: Cartridge, Non-Standard (physical fit in holder)
• Breaking Capacity: 100kA AC, 10kA DC (minimum performance threshold)
• Approval Agencies: CE, CSA, UL certifications (regulatory compliance)

The SC-30 manufactured by Eaton - Bussmann Electrical Division meets these substitution criteria with equivalent current and AC voltage ratings, higher DC voltage rating (300 VDC), matching breaking capacity, and required regulatory approvals.

Parameter Comparison

Engineering Selection Recommendations

The SC-30 is a qualified substitute for the 0SLC030.T based on the following criteria:

• Both parts maintain identical current ratings (30A) and AC voltage ratings (480 VAC)
• The SC-30 provides higher DC voltage rating (300 VDC versus 170 VDC), which is acceptable for applications requiring the 0SLC030.T
• Both parts achieve the same breaking capacity (100kA AC, 10kA DC) and are housed in compatible non-standard cartridge packages with negligible dimensional variance
• Both parts hold CE, CSA, and UL certifications and are ROHS3 compliant
• The SC-30 is ceramic construction with slow-blow response, whereas the 0SLC030.T is medium-blow; circuit design must accommodate this response time difference

Selection between these parts should be based on application-specific response time requirements and holder compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can the SC-30 replace the 0SLC030.T in all applications?

A: The SC-30 meets the electrical and mechanical substitution criteria for current rating, AC voltage, breaking capacity, and package type. However, the SC-30 has slow-blow response characteristics compared to the 0SLC030.T medium-blow response. Applications sensitive to response time must be evaluated before substitution.

Q: Why is the DC voltage rating different between these parts?

A: The SC-30 is rated for 300 VDC while the 0SLC030.T is rated for 170 VDC. A higher DC voltage rating is acceptable for substitution purposes, as it indicates the part can safely operate in applications requiring lower DC voltages.

Q: Are the physical dimensions identical?

A: The dimensions are dimensionally compatible with negligible variance. The 0SLC030.T measures 0.406" Dia x 1.626" L (10.30mm x 41.30mm), while the SC-30 measures 0.410" Dia x 1.620" L (10.41mm x 41.15mm). Both fit standard non-standard cartridge holders.

Q: What certifications apply to both parts?

A: Both the 0SLC030.T and SC-30 hold CE, CSA, and UL certifications. The 0SLC030.T additionally carries QPL approval. Both are ROHS3 compliant and REACH unaffected.

Q: Does the ceramic construction of the SC-30 affect compatibility?

A: Ceramic construction is a material specification that does not affect electrical or mechanical compatibility. The SC-30 ceramic cartridge fuse operates within the same holder and electrical parameters as the 0SLC030.T.
