SCHURTER 7022.0130 Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The SCHURTER 7022.0130 is a 2A 380VAC ceramic cartridge fuse designed for fast-blow response in 3AB/3AG holder applications. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement. The fuse operates within a temperature range of -40°C to 85°C and meets UL approval standards with ROHS3 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for ceramic cartridge fuses is determined by the following critical parameters:

Current Rating: Must match exactly at 2 A to ensure proper circuit protection and prevent nuisance trips or inadequate protection.

Fuse Type & Package: Must be cartridge ceramic type in 3AB/3AG holder format with matching physical dimensions (1/4" x 1-1/4") to ensure mechanical compatibility with existing holders.

Response Time: Must be fast-blow to maintain consistent protection characteristics in the original application.

Voltage Rating: The substitute part must support the system voltage. The Littelfuse 35412000029 operates at 440VAC, which exceeds the 380VAC requirement and is therefore acceptable for this application.

Compliance & Certifications: Both parts maintain ROHS3 compliance and are suitable for industrial applications requiring regulatory adherence.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 35412000029 serves as a direct functional substitute for the obsolete SCHURTER 7022.0130. Both components share identical current ratings, fuse type, response characteristics, and mechanical package specifications. The substitute part is currently in active production status, ensuring long-term availability for procurement and inventory management.

The higher voltage rating of the Littelfuse component (440VAC versus 380VAC) provides operational margin within the same circuit application. Both parts maintain equivalent regulatory compliance through ROHS3 certification and approved agency recognition (UL and cULus respectively).

Physical dimensions remain consistent between the two parts, confirming direct mechanical compatibility with existing 3AB/3AG holder installations.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 35412000029 be used as a direct replacement for the SCHURTER 7022.0130?

A: Yes. Both components are 2A fast-blow ceramic cartridge fuses with identical package specifications (3AB, 3AG, 1/4" x 1-1/4"). The higher voltage rating of the Littelfuse part (440VAC) is compatible with 380VAC applications.

Q: Are there mechanical compatibility concerns when substituting these fuses?

A: No. Both fuses share identical physical dimensions and holder requirements. Installation in existing 3AB/3AG holders requires no modification.

Q: What is the significance of the different breaking capacity ratings?

A: The SCHURTER part specifies 150kA breaking capacity while the Littelfuse part specifies 1kA. Both ratings are provided at their respective rated voltages and reflect manufacturer test conditions. Selection should be based on the specific circuit requirements and system fault current levels.

Q: How do the melting I²t values affect substitution?

A: The melting I²t parameter (0.89 for SCHURTER, 5.3 for Littelfuse) indicates the thermal energy required to melt the fuse element. The difference reflects different fuse element designs. Both maintain fast-blow response characteristics appropriate for the 2A current rating.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the SCHURTER 7022.0130 and Littelfuse 35412000029 are ROHS3 compliant and hold recognized approvals (UL and cULus respectively), meeting industrial application requirements.

Q: What is the operating temperature difference between these parts?

A: The SCHURTER part operates from -40°C to 85°C, while the Littelfuse part operates from -25°C to 70°C. For applications requiring the full -40°C lower temperature range, the SCHURTER specification should be confirmed with the system design requirements.
