Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 2907557 are identified based on strict parametric equivalence within the TMC 8 series. The following criteria determine substitution eligibility:

• Identical current rating: 32A
• Identical voltage ratings: 480V AC and 125V DC
• Identical breaker type: Thermal Magnetic
• Identical number of poles: 3
• Identical actuator type: Lever
• Identical mounting configuration: DIN Rail
• Same product series: TMC 8
• Active product status maintained

Parts 2907625 and 2907692 meet all substitution criteria and are fully interchangeable with the main part number 2907557.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—2907557, 2907625, and 2907692—are functionally equivalent and maintain active product status. Selection between these parts may be based on inventory availability and compliance requirements. Part 2907625 carries ROHS3 compliance certification, while parts 2907557 and 2907692 carry standard RoHS compliance. Part 2907625 additionally carries REACH Unaffected status. All parts share identical electrical specifications, mechanical configuration, and export classification (EAR99), making them suitable for direct substitution in 32A, 480V AC / 125V DC three-pole thermal magnetic circuit breaker applications on DIN Rail.

Frequently Asked Questions (FAQ)

Q: Can part 2907625 be used as a direct replacement for 2907557?

A: Yes. Both parts are identical in all electrical and mechanical parameters: 32A current rating, 480V AC / 125V DC voltage ratings, three-pole thermal magnetic configuration, lever actuation, and DIN Rail mounting. The difference in RoHS certification level (ROHS3 vs. RoHS) does not affect functional interchangeability.

Q: What is the difference between 2907557 and 2907692?

A: These parts are electrically and mechanically identical. Both carry standard RoHS compliance and share all functional specifications. They are fully interchangeable.

Q: Are all three parts suitable for 480V AC and 125V DC applications?

A: Yes. All three parts—2907557, 2907625, and 2907692—are rated for 480V AC and 125V DC operation and are suitable for dual-voltage applications requiring these specifications.

Q: Does the packaging format affect substitution?

A: No. All parts are supplied in Box packaging and are suitable for direct substitution regardless of packaging considerations.

Q: Can these parts be used interchangeably in existing installations?

A: Yes. The identical DIN Rail mounting configuration, lever actuation, and three-pole thermal magnetic design ensure mechanical and electrical compatibility in existing installations designed for the 2907557.
