TS-709-12H Equivalent & Substitute Parts

Part Overview

The TS-709-12H is a thermal circuit breaker manufactured by SCHURTER Inc., rated for 12A 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 classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS-709-12H is based on the following critical parameters that must remain consistent or compatible:

• Current Rating: 12A (exact match required)
• Breaker Type: Thermal (functional equivalence)
• Mounting Type: Panel Mount (mechanical compatibility)
• Actuator Type: Push to Reset (operational consistency)
• Number of Poles: 1 (circuit configuration)
• Voltage Ratings: AC and DC ratings must meet or exceed the original specifications
• Approval Certifications: Must maintain compliance with required standards

The substitute part 4404.0023 meets these criteria with a 12A current rating, thermal operation, panel-mount configuration, and push-to-reset actuation. Voltage ratings of 240V AC and 48V DC are within acceptable operating parameters for most applications requiring the original TS-709-12H.

Parameter Comparison

Engineering Selection Recommendations

The 4404.0023 serves as a direct functional substitute for the obsolete TS-709-12H. Both components are manufactured by SCHURTER Inc. and share identical current ratings, breaker type, mounting configuration, and actuation mechanism. The substitute maintains ROHS3 compliance and UL1077 certification, with expanded approval coverage including CSA C22.2 No 235, EN 60934, GB 17701, and IEC 60934 standards.

The voltage rating differential (240V AC vs. 250V AC; 48V DC vs. 50V DC) represents a minor reduction that remains within acceptable tolerance for most industrial and commercial applications. The active product status of 4404.0023 ensures ongoing availability and manufacturer support, addressing the obsolescence constraint of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 4404.0023 directly replace the TS-709-12H in existing installations?

A: Yes. Both components share identical current ratings (12A), breaker type (thermal), mounting configuration (panel mount), and actuation method (push to reset). The voltage ratings of the substitute are slightly lower but remain suitable for standard applications.

Q: What is the significance of the voltage rating difference?

A: The TS-709-12H is rated for 250V AC and 50V DC, while the 4404.0023 is rated for 240V AC and 48V DC. These differences are minor and do not prevent substitution in applications operating within the lower voltage specifications. System voltage requirements must be verified before installation.

Q: Are both parts certified to the same standards?

A: Both parts are certified to UL1077 and CSA C22.2. The 4404.0023 carries additional certifications including EN 60934, GB 17701, and IEC 60934, providing broader international compliance coverage.

Q: Why is the TS-709-12H classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The 4404.0023 is an active product from the same manufacturer, ensuring continued availability and technical support.

Q: Are there packaging differences between these parts?

A: The TS-709-12H packaging is listed as standard, while the 4404.0023 is packaged in boxes. This difference affects logistics and storage but does not impact functional compatibility.
