Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4400.0009 are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Critical Parameters for Substitution:

• Breaker Type: Thermal
• Current Rating: 2.5A
• Voltage Rating - AC: 240V
• Voltage Rating - DC: 48V
• Mounting Type: Panel Mount
• Actuator Type: Push to Reset
• Number of Poles: 1
• Series: T11
• Approval Agency: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077

All substitute parts listed below match these parameters exactly. Parts are grouped as parametric equivalents within the same manufacturer and series, ensuring direct functional interchangeability in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—4400.0009, 4400.0023, and 4400.0089—are Active status products manufactured by SCHURTER Inc. within the T11 series. Each part carries identical regulatory approvals (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) and maintains ROHS3 compliance with REACH Unaffected status. Selection between these parts may be based on inventory availability and procurement lead times, as all three are functionally equivalent for 2.5A thermal circuit protection at 240V AC and 48V DC in panel mount configurations.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4400.0023 or 4400.0089 be used as direct replacements for 4400.0009?

A: Yes. All three parts are parametric equivalents with identical electrical ratings (2.5A, 240V AC, 48V DC), thermal breaker type, push-to-reset actuation, single-pole configuration, and panel mount design. They carry the same regulatory approvals and compliance certifications.

Q: What determines whether a part can substitute for the 4400.0009?

A: Substitution is determined by exact matching of breaker type (thermal), current rating (2.5A), AC voltage (240V), DC voltage (48V), mounting type (panel mount), actuator type (push to reset), pole count (1), and regulatory approval agencies. All substitute parts listed meet these criteria.

Q: Are there packaging differences between these parts?

A: All parts are supplied in Bulk packaging. Packaging format does not affect electrical or mechanical interchangeability.

Q: Do all substitute parts have the same regulatory certifications?

A: Yes. All parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 approvals, ensuring compliance with the same international standards.

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

A: The three part numbers represent different manufacturing batches or internal SKU designations within SCHURTER's T11 series. From an engineering standpoint, they are functionally identical and interchangeable for circuit protection applications.
