TS-709-6.3 Circuit Breaker Thermal Equivalent & Substitute Parts

Part Overview

The TS-709-6.3 is a thermal circuit breaker manufactured by SCHURTER Inc., rated for 6.3A at 250V AC and 50V DC. This component features a push-to-reset actuator and single-pole configuration suitable for panel mount applications. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing system maintenance and new design implementations where this breaker type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS-709-6.3 is determined by the following critical parameters: current rating (6.3A or equivalent), voltage ratings (250V AC and 50V DC or higher), mounting type (panel mount), actuator type (push to reset), pole configuration (single pole), and breaker type (thermal). Parts meeting these specifications across all parameters are classified as parametric equivalents. Parts with minor deviations in current rating (6A versus 6.3A) or voltage ratings (240V AC and 48V DC) are classified as similar alternatives and require application-level verification.

The TS-709-6.3 has two parametric equivalent parts from E-T-A that match all electrical and mechanical specifications exactly. One similar alternative from SCHURTER Inc. exists with reduced current and voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

The E-T-A parts 1410-G110-P2F1-S01-6.3A and 1410-G111-P2F1-S01-6.3A are parametric equivalents to the TS-709-6.3, matching all electrical specifications and mechanical requirements. Both E-T-A parts carry active product status and hold broader approval certifications including IEC 60934 compliance. These parts are suitable for direct substitution in applications requiring the exact 6.3A/250V AC/50V DC specification.

The SCHURTER Inc. part 4404.002 is classified as a similar alternative with reduced current rating (6A) and slightly lower voltage ratings (240V AC/48V DC). This part maintains active product status and includes expanded regulatory approvals. Selection of this alternative requires confirmation that the application can operate within the reduced electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the E-T-A 1410-G110-P2F1-S01-6.3A directly replace the obsolete TS-709-6.3?

A: Yes. The 1410-G110-P2F1-S01-6.3A is a parametric equivalent with identical current rating (6.3A), voltage ratings (250V AC/50V DC), mounting type (panel mount), actuator type (push to reset), and pole configuration (single pole). Both parts are thermal breakers with the same functional characteristics.

Q: What is the difference between the two E-T-A equivalents?

A: The 1410-G110-P2F1-S01-6.3A and 1410-G111-P2F1-S01-6.3A are both from the E-T-A 1410-G1 series and share identical electrical and mechanical specifications. Both are parametric equivalents to the TS-709-6.3.

Q: Can the SCHURTER 4404.002 be used as a substitute?

A: The 4404.002 has reduced current rating (6A versus 6.3A) and lower voltage ratings (240V AC/48V DC versus 250V AC/50V DC). This part is suitable only if the application operates within these reduced specifications.

Q: What certifications apply to substitute parts?

A: The E-T-A equivalents hold CSA C22.2 No 235, IEC 60934, and UL1077 certifications. The SCHURTER 4404.002 holds CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. All parts meet RoHS compliance requirements.

Q: Are there packaging differences between the main part and substitutes?

A: The TS-709-6.3 is supplied with standard packaging. The E-T-A equivalents are supplied in bulk packaging. The SCHURTER 4404.002 is supplied in box packaging. Packaging format does not affect functional compatibility.
