TS-709-10P Thermal Circuit Breaker Equivalent & Substitute Parts

Part Overview

The TS-709-10P is a thermal circuit breaker manufactured by SCHURTER Inc., rated for 10A at 250V AC and 50V DC with push-to-reset panel mount actuation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The part carries CSA C22.2 and UL1077 approvals and is ROHS3 compliant.

Substitute Part Grouping Explanation

Substitution eligibility for the TS-709-10P is determined by the following critical parameters:

Current Rating: 10A (exact match required)
Voltage Rating - AC: 250V (exact match required)
Voltage Rating - DC: 50V (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)

All substitute parts listed below meet these electrical and mechanical specifications. The TS-709-10 (bulk packaging variant) is a parametric equivalent of the main part. Parts from E-T-A (1140 and 127 series) and SCHURTER (4404.0022) provide functional equivalence with identical electrical ratings and mechanical form factors.

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete TS-709-10P, the TS-709-10 provides identical electrical and mechanical specifications with the same SCHURTER manufacturing lineage and approval certifications.

E-T-A 1140 series parts (1140-F111-P1M1-10A, 1140-F114-P1M1-10A, 1140-G111-P1M1-10A, 1140-G151-P7M1-10A) are active products meeting all critical electrical parameters and carry CSA C22.2 No 235, IEC 60934, and UL1077 certifications.

E-T-A 127 series parts (127-F11-P10-H-KF-10A, 127-P10-H-KF-050022-10A, 127-P10-H-KF-10A) are active products with expanded certification coverage including GB 17701, suitable for applications requiring broader international compliance.

The SCHURTER 4404.0022 is an active alternative from the same manufacturer but operates at 240V AC and 48V DC, making it suitable only for applications where these lower voltage ratings are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the TS-709-10P be directly replaced with TS-709-10?

A: Yes. The TS-709-10 is a parametric equivalent with identical electrical ratings (10A, 250V AC, 50V DC), thermal breaker type, push-to-reset actuation, and panel mount configuration. Both carry the same approval certifications.

Q: What is the difference between SCHURTER and E-T-A substitute options?

A: Both manufacturers provide 10A thermal circuit breakers with 250V AC and 50V DC ratings in panel mount configuration. E-T-A parts are active products, while SCHURTER TS series parts are obsolete. E-T-A 127 series includes additional certifications (GB 17701) for broader geographic compliance.

Q: Is the SCHURTER 4404.0022 a suitable replacement?

A: The 4404.0022 is functionally equivalent in breaker type, current rating, mounting, and actuation, but operates at 240V AC and 48V DC instead of 250V AC and 50V DC. It is suitable only for applications where these lower voltage specifications are acceptable.

Q: What certifications apply to all substitute parts?

A: All listed substitutes carry UL1077 and CSA C22.2 certifications. E-T-A parts additionally carry IEC 60934 certification. The 127 series includes GB 17701 certification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant.

Q: What packaging options are available?

A: The TS-709-10 is available in bulk packaging. E-T-A and SCHURTER 4404.0022 parts are available in bulk packaging. Original TS-709-10P was supplied in standard packaging.
