Substitute Part Grouping Explanation

The SCHURTER 4410.0324 qualifies as a parametric equivalent to the 4410.0421 based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Current Rating: 400mA (exact match)
• Voltage Rating - AC: 240V (exact match)
• Voltage Rating - DC: 28V (exact match)
• Breaker Type: Thermal (exact match)
• Mounting Type: Panel Mount (exact match)
• Actuator Type: Push to Reset (exact match)
• Number of Poles: 1 (exact match)
• Series: T12 (exact match)
• Approval Agencies: Identical certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077)
• RoHS Status: ROHS3 Compliant (exact match)

Parameter Comparison

Engineering Selection Recommendations

Both the 4410.0421 and 4410.0324 are Active status products manufactured by SCHURTER Inc. and carry identical electrical ratings, mechanical specifications, and regulatory certifications. The parts are interchangeable for applications requiring a 400mA thermal circuit breaker at 240V AC / 28V DC with panel mount configuration and push-to-reset actuation. Both parts maintain full compliance with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 standards, and are ROHS3 compliant. Selection between these part numbers may be based on inventory availability and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can the 4410.0324 be used as a direct replacement for the 4410.0421?

A: Yes. Both parts are identical in electrical rating (400mA, 240V AC, 28V DC), breaker type (thermal), mounting configuration (panel mount), actuation method (push to reset), and regulatory certifications. They are parametric equivalents within the T12 series.

Q: Are there any differences in packaging or physical dimensions between these parts?

A: Both parts are supplied in Bulk packaging. No dimensional or physical differences are specified in the provided parameters.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 4410.0421 and 4410.0324 carry identical approvals: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Both are ROHS3 compliant and REACH unaffected.

Q: What is the basis for substitution between these part numbers?

A: Substitution is based on matching all critical electrical parameters (current rating, voltage ratings for AC and DC), breaker type (thermal), mounting type (panel mount), actuation type (push to reset), pole configuration (single pole), and regulatory compliance. These parameters define functional equivalence for this product category.

Q: Which part should I select if both are available?

A: Selection may be based on current inventory levels and procurement requirements. The 4410.0421 has 760 units in stock, while the 4410.0324 has 648 units available. Both are Active status products suitable for immediate use.
