Parameter Comparison

Engineering Selection Recommendations

All three part numbers (2907610, 2907543, 2907678) are active Phoenix Contact products with identical electrical and mechanical specifications. Selection between these equivalents may be based on inventory availability and compliance certifications:

• Part 2907610: ROHS3 Compliant, REACH Unaffected (996 units in stock)
• Part 2907543: RoHS Compliant (689 units in stock)
• Part 2907678: ROHS3 Compliant, REACH Unaffected (908 units in stock)

All parts carry EAR99 export classification and share the same HTSUS code. Direct substitution is supported across all three part numbers for applications requiring 4A thermal magnetic circuit protection at 480V AC / 125V DC with three-pole DIN rail mounting.

Frequently Asked Questions (FAQ)

Q: Can part 2907543 be used as a direct replacement for 2907610?

A: Yes. Both parts are Phoenix Contact TMC 8 series thermal magnetic circuit breakers with identical electrical ratings (4A, 480V AC, 125V DC), pole configuration (3-pole), and mechanical form factor (DIN rail lever actuation). The difference in RoHS certification level does not affect functional interchangeability.

Q: What is the difference between ROHS3 and RoHS compliance on these parts?

A: ROHS3 represents compliance with the latest Restriction of Hazardous Substances directive. Part 2907543 carries standard RoHS compliance, while parts 2907610 and 2907678 carry ROHS3 compliance. Both certifications indicate hazardous substance restrictions; ROHS3 reflects the current regulatory standard.

Q: Are all three parts available in the same packaging?

A: Yes. All three part numbers are supplied in box packaging, suitable for standard component distribution and installation workflows.

Q: Can these parts be mixed in the same circuit protection panel?

A: Yes. Since all three parts meet identical electrical and mechanical specifications, they can be used interchangeably within the same application or panel design without modification to mounting, wiring, or operational parameters.

Q: What inventory levels should I consider when selecting between these equivalents?

A: Current stock levels are: 2907610 (996 units), 2907678 (908 units), and 2907543 (689 units). Selection may be influenced by project timeline and procurement requirements.
