Phoenix Contact 1019925 Circuit Breaker 40A Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1019925 is a thermal magnetic circuit breaker rated for 40A at 277V AC and 60V DC, designed for DIN rail mounting with lever actuation. This single-pole breaker is part of the TMC 7 series and maintains active product status with ROHS3 compliance and REACH affected designation. Substitute parts become necessary when addressing inventory constraints, regional compliance variations, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for Phoenix Contact 1019925 is determined by strict parametric equivalence across the following critical parameters: breaker type (thermal magnetic), current rating (40A), AC voltage rating (277V), DC voltage rating (60V), mounting configuration (DIN rail), actuator mechanism (lever), pole count (single), and series designation (TMC 7). All substitute parts must maintain identical electrical performance characteristics and mechanical form factor to ensure direct interchangeability without circuit modification or reconfiguration.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—1019925, 1019989, and 1020056—are parametrically equivalent and maintain active product status. Selection between these parts should be based on compliance requirements and inventory availability. Part 1019925 carries REACH Affected designation, while both 1019989 and 1020056 are REACH Unaffected. For applications requiring REACH compliance documentation, 1019989 or 1020056 are appropriate selections. Current inventory levels are 984 units for 1019925, 673 units for 1019989, and 711 units for 1020056. All parts maintain ROHS3 compliance and identical electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can 1019989 or 1020056 be used as direct replacements for 1019925?

A: Yes. All three parts are parametrically equivalent across current rating, voltage ratings, mounting type, actuator mechanism, and pole configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between REACH Affected and REACH Unaffected designations?

A: REACH Affected (1019925) indicates the part contains substances of very high concern requiring specific compliance documentation. REACH Unaffected (1019989, 1020056) indicates no such substances are present. Selection depends on regulatory requirements for your application region.

Q: Are all three parts suitable for 277V AC and 60V DC applications?

A: Yes. All three parts maintain identical voltage ratings of 277V AC and 60V DC and are rated for thermal magnetic operation at 40A across both voltage specifications.

Q: Does packaging differ between these part numbers?

A: No. All three parts are supplied in box packaging with identical specifications.

Q: Can these parts be mixed in the same installation?

A: Yes. Since all three parts are parametrically equivalent with identical electrical and mechanical characteristics, they can be used interchangeably within the same DIN rail installation.
