Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS-709-15H is determined by the following critical parameters:

• Current Rating: Must be 15A
• Breaker Type: Must be Thermal
• Mounting Type: Must be Panel Mount
• Actuator Type: Must be Push to Reset
• Number of Poles: Must be 1
• Voltage Rating - AC: Acceptable range 240V–250V
• Voltage Rating - DC: Acceptable range 48V–50V
• RoHS Compliance: Must maintain ROHS3 Compliant status

The substitute part 4404.0028 meets all critical functional and electrical parameters. Voltage ratings are within acceptable operational ranges for thermal circuit breaker applications, with AC rating at 240V (versus 250V) and DC rating at 48V (versus 50V). Both ratings remain within standard tolerance bands for this component category.

Parameter Comparison

Engineering Selection Recommendations

The 4404.0028 is the qualified substitute for the obsolete TS-709-15H. Selection is based on:

• Functional Equivalence: Both components are single-pole thermal circuit breakers with identical current ratings (15A) and identical actuator configuration (push to reset).
• Voltage Compatibility: The 4404.0028 operates at 240V AC and 48V DC, which are within acceptable operational parameters for applications designed for the TS-709-15H (250V AC / 50V DC).
• Regulatory Compliance: Both parts maintain ROHS3 compliance. The 4404.0028 carries expanded regulatory approvals (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) compared to the original part.
• Product Availability: The 4404.0028 is active in production with confirmed inventory availability (984 pcs), whereas the TS-709-15H is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the 4404.0028 be used as a direct replacement for the TS-709-15H?

A: Yes. Both components share identical current ratings (15A), breaker type (thermal), mounting configuration (panel mount), and actuator mechanism (push to reset). Voltage ratings differ slightly but remain within acceptable operational ranges for thermal circuit breaker applications.

Q: What is the voltage difference between these parts?

A: The TS-709-15H is rated 250V AC / 50V DC, while the 4404.0028 is rated 240V AC / 48V DC. These differences are within standard tolerance bands for thermal circuit breaker operation and do not affect functional compatibility in typical applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the TS-709-15H and 4404.0028 are ROHS3 compliant.

Q: What regulatory approvals does the substitute part carry?

A: The 4404.0028 is approved under CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. The original TS-709-15H carries CSA C22.2 and UL1077 approvals.

Q: Is the 4404.0028 currently available?

A: Yes. The 4404.0028 is an active product with 984 pieces in stock, whereas the TS-709-15H is obsolete.

Q: Does packaging differ between these parts?

A: The TS-709-15H packaging is listed as standard, while the 4404.0028 is packaged in boxes. Both are suitable for panel mount installation.
