Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4430.0004 are identified based on strict parametric equivalence across the following critical specifications:

• Current Rating: 4.5A
• Voltage Rating - AC: 240V
• Voltage Rating - DC: 60V
• Breaker Type: Thermal
• Mounting Type: Panel Mount
• Actuator Type: Rocker
• Number of Poles: 2
• Series: TA45

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without modification to circuit design or mechanical installation.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 4430.0004 and 4430.0428 are active production components with identical electrical ratings, mechanical configurations, and regulatory compliance. Both parts are ROHS3 compliant and REACH unaffected, meeting the same approval standards including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Selection between these parts may be based on inventory availability and procurement lead times, as they are parametrically equivalent for all specified applications.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4430.0428 be used as a direct replacement for 4430.0004?

A: Yes. Both parts are parametrically equivalent across all critical specifications: 4.5A current rating, 240V AC / 60V DC voltage ratings, thermal breaker type, rocker actuator, 2-pole configuration, and panel mount design. No circuit or mechanical modifications are required.

Q: Are there any differences in regulatory compliance between these parts?

A: Both parts meet identical approval standards and are ROHS3 compliant. No compliance differences exist between the two part numbers.

Q: What is the basis for substitution between these parts?

A: Substitution is based on matching electrical ratings (current and voltage), breaker type (thermal), actuator configuration (rocker), pole count (2), and mounting method (panel mount). Parts meeting all these parameters are functionally equivalent.

Q: Does packaging differ between these part numbers?

A: Both parts are supplied in bulk packaging. No packaging differences exist.

Q: Which part should be selected if both are available?

A: Selection may be based on current inventory levels and procurement timelines. The SCHURTER 4430.0004 has 808 units in stock, while the 4430.0428 has 827 units in stock. Both are equally suitable for the application.
