TS-709-12.5H Equivalent & Substitute Parts

Part Overview

The TS-709-12.5H is a thermal circuit breaker manufactured by SCHURTER Inc., rated for 12.5A at 250V AC and 50V DC. This single-pole, panel-mount device features push-to-reset actuation and is certified to CSA C22.2 and UL1077 standards. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications where this breaker is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS-709-12.5H is determined by the following critical parameters:

• Breaker Type: Thermal operation must be maintained
• Mounting Configuration: Panel mount form factor required
• Actuator Mechanism: Push-to-reset functionality must be preserved
• Pole Count: Single-pole configuration
• Current Rating: Electrical compatibility within acceptable tolerance
• Voltage Ratings: AC and DC voltage specifications must meet or exceed application requirements
• Regulatory Compliance: Certifications must satisfy end-use standards

The substitute part 4404.0023 maintains thermal breaker operation, panel-mount configuration, push-to-reset actuation, and single-pole design. Current and voltage ratings are within acceptable parameters for applications designed for the TS-709-12.5H, with the substitute providing 12A at 240V AC and 48V DC compared to the original 12.5A at 250V AC and 50V DC.

Parameter Comparison

Engineering Selection Recommendations

The 4404.0023 is suitable as a substitute for the TS-709-12.5H based on the following factors:

• Both components are manufactured by SCHURTER Inc. and share identical thermal breaker architecture, panel-mount configuration, and push-to-reset actuation
• The substitute maintains single-pole operation and is certified to UL1077, matching the primary approval standard of the original part
• The substitute holds active product status with expanded regulatory compliance (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934), providing broader international recognition
• Current and voltage ratings of the substitute (12A at 240V AC, 48V DC) are within acceptable operating parameters for circuits originally designed for 12.5A at 250V AC and 50V DC
• Both parts are ROHS3 compliant and REACH unaffected, ensuring environmental and regulatory alignment
• The substitute is available in active inventory, addressing the obsolescence of the original part

Frequently Asked Questions (FAQ)

Q: Can the 4404.0023 directly replace the TS-709-12.5H in existing installations?

A: Yes, provided the circuit design does not depend on the specific 12.5A current rating or 250V AC / 50V DC voltage specifications. The substitute maintains identical form factor, mounting, actuation, and thermal operation. Verify that your application can operate within the substitute's 12A and 240V AC / 48V DC ratings.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (12.5A vs. 12A), AC voltage rating (250V vs. 240V), and DC voltage rating (50V vs. 48V). The substitute also belongs to a different series (T9-311 vs. TS) and includes additional regulatory certifications (EN 60934, GB 17701, IEC 60934).

Q: Are both parts certified to the same standards?

A: Both parts are certified to CSA C22.2 and UL1077. The substitute includes additional certifications: CSA C22.2 No 235, EN 60934, GB 17701, and IEC 60934, providing broader international compliance.

Q: What is the packaging difference?

A: The TS-709-12.5H packaging is listed as standard, while the 4404.0023 is supplied in box packaging. Both are suitable for panel-mount installation.

Q: Is the substitute available in inventory?

A: Yes, the 4404.0023 is an active product with 1,491 pieces in new original stock, compared to the obsolete TS-709-12.5H with 650 pieces remaining.
