TS-709-12.5 Circuit Breaker Thermal - Equivalent & Substitute Parts

Part Overview

The TS-709-12.5 is a single-pole thermal circuit breaker rated for 12.5A at 250V AC and 50V DC, featuring push-to-reset actuation and panel mount configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy specifications must be maintained or adapted.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 4404.0023 qualifies as an equivalent alternative based on the following matching parameters:

• Manufacturer: SCHURTER Inc. (same manufacturer ensures design compatibility and quality standards)
• Breaker Type: Thermal (identical protection mechanism)
• Mounting Type: Panel Mount (same physical installation method)
• Actuator Type: Push to Reset (identical user interface)
• Number of Poles: 1 (same circuit configuration)
• RoHS Status: ROHS3 Compliant (equivalent environmental compliance)
• Approval Agencies: Includes UL1077 (primary certification match)

The substitute part operates at slightly reduced current and voltage ratings (12A at 240V AC and 48V DC versus 12.5A at 250V AC and 50V DC). This represents a conservative electrical specification suitable for applications where the original part's ratings exceed system requirements.

Parameter Comparison

Engineering Selection Recommendations

The 4404.0023 serves as a direct functional substitute for the obsolete TS-709-12.5 in applications where the reduced electrical ratings are acceptable. Selection criteria are based on the following factors:

Product Status Consideration: The TS-709-12.5 is obsolete with no ongoing manufacturing. The 4404.0023 is in active production, ensuring long-term availability and supply chain continuity.

Certification Alignment: Both parts meet UL1077 and CSA C22.2 standards. The 4404.0023 additionally qualifies under EN 60934, GB 17701, and IEC 60934, providing broader international compliance coverage.

Electrical Rating Compatibility: The substitute's 12A current rating and 240V AC / 48V DC voltage ratings are lower than the original specification. This substitution is appropriate for circuits designed to operate within these reduced parameters or where the original ratings provided design margin.

Physical and Functional Equivalence: Identical mounting type, actuator mechanism, pole configuration, and thermal protection principle ensure mechanical and operational compatibility within the specified electrical envelope.

Frequently Asked Questions (FAQ)

Q: Can the 4404.0023 directly replace the TS-709-12.5 in all applications?

A: Direct replacement is suitable only for applications where circuit current does not exceed 12A and voltage does not exceed 240V AC or 48V DC. If the original design requires the full 12.5A or 250V AC / 50V DC ratings, alternative solutions must be evaluated.

Q: What is the primary difference between these two parts?

A: The main differences are product status (obsolete versus active production) and electrical ratings. The 4404.0023 operates at slightly lower current and voltage specifications while maintaining identical thermal protection functionality and mounting configuration.

Q: Are there packaging differences between these parts?

A: The TS-709-12.5 packaging is listed as standard, while the 4404.0023 is supplied in box packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Do both parts meet the same safety certifications?

A: Both parts meet UL1077 and CSA C22.2 standards. The 4404.0023 includes additional certifications (EN 60934, GB 17701, IEC 60934) for broader geographic compliance.

Q: What is the inventory status of these parts?

A: The TS-709-12.5 has 960 pieces in stock as new original inventory. The 4404.0023 has 1491 pieces available, reflecting its active production status.

Q: Are both parts RoHS compliant?

A: Yes, both the TS-709-12.5 and 4404.0023 are ROHS3 compliant and REACH unaffected.
