SCHURTER 4404.0001 Circuit Breaker Thermal 4A 240VAC 48VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4404.0001 is a thermal circuit breaker rated for 4A at 240V AC and 48V DC, designed for panel mount applications with push-to-reset actuation. This component is classified as Active product status with full compliance to international safety standards. Substitute parts become necessary when the primary part number experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives within the same electrical and mechanical parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4404.0001 is determined by strict equivalence across the following critical parameters:

• Current Rating: 4A (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 Agency certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 (all required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 4404.0019 meets all these criteria and is therefore classified as a parametric equivalent. Series designation differences (T9-611 vs. T9-311) reflect internal SCHURTER product line organization and do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 4404.0001 and 4404.0019 are Active status products with identical electrical ratings, mechanical configurations, and regulatory compliance. Selection between these part numbers may be based on inventory availability and lead time considerations. Both components satisfy the same application requirements for 4A thermal circuit protection at 240V AC / 48V DC with panel mount configuration.

The identical approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) and ROHS3 compliance status confirm that either part number is suitable for applications requiring these regulatory qualifications.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4404.0019 be used as a direct replacement for SCHURTER 4404.0001?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (4A, 240V AC, 48V DC), thermal breaker type, push-to-reset actuation, panel mount configuration, and regulatory certifications. The series designation difference does not affect functional compatibility.

Q: Are there any differences in physical dimensions or mounting between these two part numbers?

A: The provided specifications confirm identical mounting type (Panel Mount) and actuator type (Push to Reset) for both parts. No dimensional variations are indicated in the available parameter data.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SCHURTER 4404.0001 and 4404.0019 carry identical approval agency certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the T9-611 and T9-311 series designations?

A: Series designations reflect SCHURTER's internal product line organization. Both series meet identical electrical and mechanical specifications for this 4A thermal circuit breaker application.

Q: Can I mix these part numbers in the same design or assembly?

A: Yes. Since both parts are parametric equivalents with identical electrical ratings, mechanical configuration, and regulatory compliance, they can be used interchangeably within the same circuit design or assembly.
