Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4400.003 are qualified based on strict parametric equivalence across the following criteria:

• Current Rating: 10A (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)
• Approval Agencies: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 (all certifications maintained)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitutes meet these parameters without exception. Series designation and internal construction may vary between equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

All three parts—4400.003, 4400.0003, and 4404.0059—are Active status products manufactured by SCHURTER Inc. and carry identical electrical ratings and regulatory certifications. Selection between these parts may be based on inventory availability and series designation. The 4400.003 and 4400.0003 share the T11 series designation, while 4404.0059 belongs to the T9-611 series. All parts maintain full compliance with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 standards, and all are ROHS3 compliant. No technical performance differentiation exists between these parts based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Can 4400.0003 or 4404.0059 be used as direct replacements for 4400.003?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (10A, 240V AC, 48V DC), thermal breaker type, panel mount configuration, push-to-reset actuation, and regulatory certifications. They are functionally interchangeable in circuit protection applications.

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

A: Series designation indicates internal design generation or manufacturing revision. Both series meet identical electrical and safety specifications for this 10A 240VAC 48VDC thermal breaker application. The series difference does not affect functional compatibility.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—4400.003, 4400.0003, and 4404.0059—are ROHS3 compliant and carry identical regulatory certifications.

Q: Which part should I select if all three are equivalent?

A: Selection should be based on inventory availability, lead time, and packaging requirements. All three parts are Active status products with identical electrical performance and compliance certifications.

Q: Do these parts require any special handling or installation considerations?

A: Installation and handling requirements are determined by the panel mount configuration and push-to-reset mechanism common to all three parts. Refer to SCHURTER technical documentation for specific mounting and operational procedures.
