Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4400.0031 is determined by strict equivalence across the following critical parameters:

• Current Rating: 12A (exact match required)
• Voltage Rating AC: 240V (exact match required)
• Voltage Rating DC: 48V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Push to Reset (exact match required)
• Number of Poles: 1 (exact match required)
• Manufacturer: SCHURTER Inc. (same manufacturer)
• Product Status: Active (current production)
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)

All identified substitute parts meet these criteria without exception. Series designation (T11 or T9-611) does not restrict substitution when all electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers (4400.0031, 4400.0052, 4400.0279, 4404.0061) are functionally equivalent and directly interchangeable based on electrical and mechanical specifications. Selection among these parts may be based on:

• Inventory availability and lead time requirements
• Procurement source and pricing
• Design documentation and historical usage
• Regulatory compliance requirements (all parts meet CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 standards where applicable)

All parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can 4400.0052, 4400.0279, and 4404.0061 be used as direct replacements for 4400.0031?

A: Yes. All parts share identical electrical ratings (12A, 240V AC, 48V DC), breaker type (thermal), mounting configuration (panel mount), and actuation method (push to reset). They are parametrically equivalent and directly interchangeable.

Q: What is the difference between the T11 and T9-611 series designations?

A: Series designation indicates internal design generation or manufacturing platform. When all electrical and mechanical parameters are identical, series differences do not affect functional compatibility or substitution eligibility.

Q: Are there any compliance or certification differences between these parts?

A: Part 4400.0279 does not list specific approval agencies in the provided data. Parts 4400.0031, 4400.0052, and 4404.0061 are certified to CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. All parts are ROHS3 compliant and REACH unaffected.

Q: Which part should I select if inventory is a concern?

A: Part 4404.0061 has the highest inventory level (1075 pcs), followed by 4400.0031 (1057 pcs). Selection should align with procurement timelines and supply chain requirements.

Q: Are these parts suitable for both AC and DC applications?

A: Yes. All parts are rated for 240V AC and 48V DC operation, supporting dual-voltage applications within these specified ranges.
