Substitute Part Grouping Explanation

Substitution eligibility for the TS-709-10H 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)

Engineering Selection Recommendations

For direct replacement of the obsolete TS-709-10H, the parametric equivalent TS-709-10 from SCHURTER Inc. provides identical electrical specifications and maintains the same approval certifications (CSA C22.2, UL1077). This part is also obsolete but shares the same base product number (TS-709).

For active production designs, E-T-A series 1140 and 127 thermal circuit breakers offer full parametric equivalence at 10A, 250V AC, and 50V DC with push-to-reset panel mount configuration. These parts carry expanded regulatory approvals including IEC 60934 and CSA C22.2 No 235, supporting broader international compliance requirements.

The SCHURTER 4404.0022 operates at reduced voltage ratings (240V AC, 48V DC) and is suitable only for applications where the lower voltage specification is acceptable. This part carries active product status and expanded certifications (EN 60934, GB 17701).

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical specifications (10A, 250V AC, 50V DC), thermal breaker type, push-to-reset actuation, and panel mount configuration. Both carry CSA C22.2 and UL1077 approvals. The primary difference is packaging (TS-709-10H in individual packaging versus TS-709-10 in bulk).

Q: Are E-T-A series 1140 and 127 parts fully compatible with TS-709-10H?

A: Yes. All E-T-A parts listed (1140-F111-P1M1-10A, 1140-F114-P1M1-10A, 1140-G111-P1M1-10A, 1140-G151-P7M1-10A, 127-F11-P10-H-KF-10A, 127-P10-H-KF-050022-10A, 127-P10-H-KF-10A) meet all critical electrical and mechanical parameters. These parts carry active product status and include IEC 60934 certification in addition to CSA C22.2 and UL1077.

Q: What is the difference between the E-T-A 1140 and 127 series?

A: Both series meet identical electrical specifications for this 10A application. The series designation reflects different product lines within E-T-A's thermal circuit breaker portfolio. Selection between series depends on internal design requirements and part availability.

Q: Can SCHURTER 4404.0022 be used as a substitute?

A: The 4404.0022 operates at 240V AC and 48V DC, which are lower than the TS-709-10H specification of 250V AC and 50V DC. This part is suitable only for applications where the reduced voltage rating is acceptable. All other parameters (10A current, thermal type, push-to-reset, panel mount, single pole) are equivalent.

Q: What certifications should I verify for my application?

A: The TS-709-10H carries CSA C22.2 and UL1077 approvals. E-T-A substitutes expand this to include IEC 60934 and CSA C22.2 No 235. The SCHURTER 4404.0022 adds EN 60934 and GB 17701. Confirm that your application requirements align with the certification scope of your selected part.

Q: Are there packaging differences between substitute parts?

A: Yes. TS-709-10H is supplied in individual packaging, TS-709-10 in bulk, and all E-T-A parts in bulk packaging. Packaging does not affect electrical or mechanical compatibility but may impact procurement and inventory management.
