Phoenix Contact 2907539 Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2907539 is a thermal magnetic circuit breaker rated for 1A at 480V AC and 125V DC, designed for DIN rail mounting. This three-pole lever-actuated breaker is part of the TMC 8 series and maintains active product status with full RoHS compliance. Equivalent substitute parts are necessary to ensure supply chain continuity, support procurement flexibility, and provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require alternative selection.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2907539 is determined by strict parametric equivalence across all critical electrical and mechanical specifications. The substitute parts 2907607 and 2907674 are classified as parametric equivalents because they maintain identical values across all defining characteristics: thermal magnetic breaker type, 1A current rating, 480V AC and 125V DC voltage ratings, three-pole configuration, lever actuation, and DIN rail mounting. All parts belong to the TMC 8 series and share identical packaging specifications. Substitution is valid when these parameters remain constant across the application requirement.

Parameter Comparison

Engineering Selection Recommendations

Part 2907607 carries ROHS3 compliance certification and REACH affected status, providing enhanced regulatory documentation for applications requiring extended compliance tracking. Parts 2907539 and 2907674 maintain standard RoHS compliance. Current inventory levels are 714 units (2907539), 816 units (2907607), and 894 units (2907674), supporting procurement decisions based on delivery requirements and supply chain strategy.

Frequently Asked Questions (FAQ)

Q: Can part 2907607 be used as a direct replacement for 2907539? A: Yes. Both parts are parametric equivalents with identical electrical ratings (1A, 480V AC, 125V DC), mechanical configuration (3-pole, lever-actuated, DIN rail mount), and thermal magnetic breaker type. The difference in RoHS certification level (ROHS3 vs. RoHS) does not affect functional compatibility.

Q: What is the difference between 2907539 and 2907674? A: These parts are parametric equivalents with identical specifications across all electrical and mechanical parameters. Both maintain standard RoHS compliance. No functional or performance differences exist between these part numbers.

Q: Are all three parts interchangeable in the same circuit application? A: Yes. All three parts meet identical electrical and mechanical requirements for 1A thermal magnetic circuit protection at 480V AC and 125V DC with three-pole lever actuation on DIN rail. Substitution is valid for any application requiring these specifications.

Q: Does the ROHS3 compliance of part 2907607 provide additional benefits? A: ROHS3 compliance indicates adherence to the most current Restriction of Hazardous Substances directive. For applications requiring documented compliance with the latest regulatory standards, part 2907607 provides enhanced certification documentation. Functional performance remains identical across all three parts.

Q: What packaging format is used for these circuit breakers? A: All three part numbers are supplied in box packaging, suitable for standard component storage and distribution workflows.
