TS-701-HT-25 Equivalent & Substitute Parts

Part Overview

The TS-701-HT-25 is a thermal circuit breaker manufactured by SCHURTER Inc., rated for 25A at 250V AC and 50V DC with push-to-reset panel mount actuation. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The breaker is single-pole, thermally actuated, and approved under CSA C22.2 and UL1077 standards. ROHS3 compliance and REACH unaffected status ensure environmental regulatory alignment.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TS-701-HT-25 is determined by strict equivalence across the following critical parameters:

• Current Rating: 25A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Voltage Rating - DC: 50V or higher (50V minimum acceptable)
• 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)

Substitute parts are categorized into two groups:

Parametric Equivalents (Full Specification Match): Parts meeting all electrical and mechanical parameters with identical 50V DC rating. These are direct replacements with no derating considerations.

Similar Substitutes (Reduced DC Voltage Rating): Parts meeting all parameters except DC voltage rating, which is reduced to 32V. These parts are suitable only for applications where the DC voltage requirement does not exceed 32V.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent Selection (Preferred): E-T-A series parts 127-P10-H-KF-050022-25A, 127-P10-H-KF-25A, 127-P10-H-KF-D91-25A, 157-K10-KF-25A, 157-P10-KF-25A, 2-5000-K10-25A, and 2-5000-K10-H-25A provide full specification equivalence to the TS-701-HT-25. All are active products with expanded approval certifications including CSA C22.2 No 235, GB 17701, and IEC 60934, providing broader international compliance. ROHS3 compliance and REACH unaffected status are maintained across all E-T-A equivalents.

Similar Substitute Selection (Conditional): Carling Technologies CLB-253-11ANN-B-A and CLB-253-11BNN-B-F are suitable only for applications where the DC voltage requirement does not exceed 32V. The CLB-303-11BNN-B-F is not suitable due to current rating mismatch (30A vs. 25A required). Carling parts provide active product status and expanded certifications including CE, cUL, and TUV, but the reduced DC voltage rating requires application-level verification before selection.

Frequently Asked Questions (FAQ)

Q: Can CLB-253-11ANN-B-A or CLB-253-11BNN-B-F be used as direct replacements for TS-701-HT-25?

A: These Carling Technologies parts meet all electrical and mechanical parameters except DC voltage rating, which is 32V instead of 50V. They are suitable only if your application operates at 32V DC or lower. If your system requires 50V DC operation, use E-T-A parametric equivalents.

Q: Why is CLB-303-11BNN-B-F listed if it cannot replace TS-701-HT-25?

A: CLB-303-11BNN-B-F has a current rating of 30A, not 25A. It does not meet the substitution criteria and is included for reference only. Current rating must match exactly for thermal circuit breaker selection.

Q: What is the difference between the E-T-A 127 and 157 series parts?

A: Both series meet identical electrical and mechanical specifications for the TS-701-HT-25 replacement. The series designation reflects internal design architecture but does not affect functional equivalence. Selection between series can be based on availability or application-specific mechanical considerations.

Q: Are all E-T-A equivalents interchangeable?

A: Yes. All E-T-A parts listed (127-P10-H-KF-050022-25A, 127-P10-H-KF-25A, 127-P10-H-KF-D91-25A, 157-K10-KF-25A, 157-P10-KF-25A, 2-5000-K10-25A, and 2-5000-K10-H-25A) meet full parametric equivalence with identical 25A, 250V AC, and 50V DC ratings. Selection can be based on packaging availability or lead time.

Q: What compliance certifications should I verify for my application?

A: The TS-701-HT-25 is approved under CSA C22.2 and UL1077. E-T-A equivalents expand this to include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. Carling alternatives provide CE, cUL, TUV, UL1077, and UL1500. Verify that your application requirements align with the certifications of your selected substitute.
