• Voltage rating: 480V AC and 125V DC
• Breaker type: Thermal Magnetic
• Number of poles: 3
• Mounting type: DIN Rail
• Actuator type: Lever
• Series: TMC 8
• Manufacturer: Phoenix Contact
• Product status: Active
• Compliance: ROHS3 Compliant

All substitute parts listed maintain identical electrical and mechanical specifications, ensuring functional interchangeability without circuit redesign or recalibration.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—2907621, 2907553, and 2907689—are active products within the Phoenix Contact TMC 8 series with identical electrical and mechanical specifications. Selection between these equivalents is based on availability and supply chain requirements rather than functional differences. All parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial control applications. Component selection should prioritize inventory availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Are Phoenix Contact 2907621, 2907553, and 2907689 directly interchangeable?

A: Yes. All three part numbers are parametric equivalents with identical current ratings (20A), voltage ratings (480V AC / 125V DC), breaker type (thermal magnetic), pole configuration (3-pole), mounting type (DIN Rail), and actuator type (lever). Direct substitution is valid without circuit modification.

Q: What determines if a circuit breaker can substitute for the 2907621?

A: Substitution is valid when the replacement part maintains the same current rating (20A), voltage ratings (480V AC and 125V DC), breaker type (thermal magnetic), number of poles (3), mounting type (DIN Rail), and actuator type (lever) within the TMC 8 series.

Q: Do all substitute parts have the same packaging?

A: Yes. All listed substitute parts are supplied in box packaging, consistent with the main part number 2907621.

Q: Are there compliance differences between these part numbers?

A: No. All three part numbers maintain identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 ECCN classification.

Q: Which part number should I select based on availability?

A: Selection should be based on current inventory levels and supply chain lead times. As of the reference date, 2907621 has 1103 units in stock, 2907689 has 939 units, and 2907553 has 755 units available.
