• Voltage Rating - AC: 240V (identical across all three parts)
• Voltage Rating - DC: 48V (identical across all three parts)
• Breaker Type: Thermal (identical across all three parts)
• Mounting Type: Panel Mount (identical across all three parts)
• Actuator Type: Push to Reset (identical across all three parts)
• Number of Poles: 1 (identical across all three parts)
• Series: T11 (identical across all three parts)
• Approval Agency: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 (identical across all three parts)
• RoHS Status: ROHS3 Compliant (identical across all three parts)
• REACH Status: REACH Unaffected (identical across all three parts)

All three parts share identical electrical and mechanical specifications, making them direct substitutes within the same product family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—4400.0735, 4400.035, and 4400.0747—are functionally equivalent and carry Active product status. Selection between these parts should be based on:

• Inventory availability: 4400.0747 has the highest stock level at 1236 pieces, followed by 4400.035 at 973 pieces, and 4400.0735 at 803 pieces.
• Compliance requirements: All three parts meet identical international safety certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) and environmental standards (ROHS3 Compliant, REACH Unaffected).
• Supply chain continuity: Any of the three parts can be substituted without modification to circuit design, PCB layout, or system integration.

Frequently Asked Questions (FAQ)

Q: Can 4400.035 or 4400.0747 be used as direct replacements for 4400.0735?

A: Yes. All three parts are parametric equivalents with identical electrical ratings (50mA, 240V AC, 48V DC), mechanical specifications (panel mount, push-to-reset, single-pole thermal breaker), and regulatory certifications. Direct substitution is supported without design changes.

Q: Are there any differences in approval certifications between these parts?

A: No. All three parts carry identical approvals: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. They meet the same regulatory requirements for use in equivalent applications.

Q: What is the difference between these part numbers if they are equivalent?

A: The part numbers represent different manufacturing batches or internal SKU designations within the SCHURTER T11 series. The electrical and mechanical specifications are identical, making them interchangeable for circuit protection applications requiring 50mA thermal protection at 240V AC or 48V DC.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—4400.0735, 4400.035, and 4400.0747—are ROHS3 Compliant and REACH Unaffected, meeting environmental and hazardous substance restrictions for industrial and commercial applications.

Q: Which part should be selected for new designs?

A: From a compliance and specification standpoint, any of the three parts is suitable. Selection should prioritize inventory availability and supply chain lead times. Currently, 4400.0747 offers the highest stock level.
