SCHURTER 4430.1474 Circuit Breaker Thermal 8A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.1474 is an active thermal circuit breaker rated for 8A at 240V AC and 60V DC, featuring a rocker panel mount actuator with dual-pole configuration. This component is designed for overcurrent protection in industrial and commercial electrical systems. Substitute parts become necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from equivalent models within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric equivalence across the following criteria:

Current Rating: 8A (exact match required)
Voltage Rating AC: 240V (exact match required)
Voltage Rating DC: 60V (exact match required)
Breaker Type: Thermal (exact match required)
Mounting Type: Panel Mount (exact match required)
Actuator Type: Rocker (exact match required)
Number of Poles: 2 (exact match required)
Product Status: Active (all substitutes must be active)
RoHS Compliance: ROHS3 Compliant (all substitutes must comply)

All substitute parts listed below meet these criteria. Series designation (TA45 or TA35) does not restrict substitution eligibility when all electrical and mechanical parameters are identical.

Engineering Selection Recommendations

All listed substitute parts are manufactured by SCHURTER Inc. and maintain active product status. Selection among equivalent parts should be based on inventory availability and compliance certification requirements. Parts bearing CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications are suitable for applications requiring these specific regulatory approvals. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for industrial component sourcing.

Frequently Asked Questions (FAQ)

Q: Can 4430.1474 be directly replaced with any part from the substitute list?

A: Yes. All substitute parts meet identical electrical specifications (8A, 240V AC, 60V DC), mechanical configuration (panel mount, rocker actuator, dual-pole), and regulatory compliance (ROHS3, active status). Direct substitution is permissible without circuit redesign.

Q: What is the difference between TA45 and TA35 series parts?

A: Series designation does not affect electrical or mechanical compatibility. Both TA45 and TA35 series parts in this list share identical current ratings, voltage ratings, mounting type, actuator type, and pole configuration. Series designation reflects internal design architecture but does not restrict interchangeability when all specified parameters match.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including 4430.1474 and all substitutes, are ROHS3 compliant. No exceptions exist within this substitute group.

Q: Which substitute part has the highest inventory availability?

A: Part number 4430.0423 has the highest inventory at 1031 pieces, followed by 4430.3661 at 1018 pieces.

Q: Do all parts carry the same regulatory certifications?

A: Most parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Part 4430.0646 and 4435.0272 do not list approval agency certifications in the provided data. Verify certification requirements for your specific application before final selection.

Q: Can packaging type affect substitution eligibility?

A: All parts are supplied in bulk packaging. Packaging type does not affect electrical or mechanical compatibility and does not restrict substitution.
