SCHURTER 4430.0709 Thermal Circuit Breaker 12A 240VAC 60VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4430.0709 is a thermal circuit breaker rated for 12A at 240V AC and 60V DC, featuring a rocker panel mount actuator with dual-pole configuration. This component is classified as Active product status and complies with international safety standards including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. The part is ROHS3 compliant and REACH unaffected.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when procurement lead times require alternative sourcing, or when design flexibility permits selection from qualified alternatives within the same electrical and mechanical parameter set.

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4430.0709 is determined by strict parametric equivalence across the following criteria:

Current Rating: 12A (mandatory match)
Voltage Rating AC: 240V (mandatory match)
Voltage Rating DC: 60V (mandatory match)
Breaker Type: Thermal (mandatory match)
Mounting Type: Panel Mount (mandatory match)
Actuator Type: Rocker (mandatory match)
Number of Poles: 2 (mandatory match)
Manufacturer: SCHURTER Inc. (mandatory match)
Compliance: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077 (mandatory match)
RoHS Status: ROHS3 Compliant (mandatory match)

All substitute parts listed meet these criteria. Parts are grouped by series designation: TA45 series (primary group) and TA35 series (alternative series with identical electrical and mechanical parameters).

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and comply with the same international safety standards as the primary part 4430.0709. Selection among equivalent parts may be based on inventory availability and procurement lead times.

TA45 series parts (4430.0024, 4430.1034, 4430.1637, 4430.242, 4430.2693, 4430.3041, 4430.3223, 4430.3263) are direct series equivalents to the primary part 4430.0709.

TA35 series parts (4435.0092, 4435.0223) represent an alternative series designation while maintaining identical electrical specifications, current rating, voltage ratings, mounting configuration, and actuator type. These parts are suitable for applications where series flexibility is permitted by design specifications.

All parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can TA35 series parts replace TA45 series parts? A: Yes. Both series maintain identical electrical parameters (12A, 240V AC, 60V DC), thermal breaker type, rocker actuator, dual-pole configuration, and panel mount design. Series designation does not affect functional equivalence for this product category.

Q: What determines if a part is a valid substitute for 4430.0709? A: A valid substitute must match all mandatory parameters: 12A current rating, 240V AC voltage, 60V DC voltage, thermal breaker type, rocker actuator, dual-pole configuration, panel mount design, and SCHURTER Inc. manufacture. All listed parts meet these criteria.

Q: Are there differences in compliance certifications between substitute parts? A: TA45 series parts carry full compliance with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. TA35 series parts (4435.0092, 4435.0223) carry ROHS3 compliance and REACH unaffected status. Verify specific certification requirements for your application before selection.

Q: How should inventory levels influence part selection? A: Inventory availability is provided for procurement planning. Part 4430.242 maintains the highest inventory at 1168 pieces. Selection should prioritize application requirements and compliance needs over inventory levels.

Q: Is MSL (Moisture Sensitivity Level) a factor in substitution? A: MSL is not applicable to thermal circuit breakers and does not affect substitution eligibility. Part 4430.242 lists MSL as Vendor Undefined; this does not impact functional equivalence.
