Substitute Part Grouping Explanation

The 3C15UM qualifies for direct substitution with 3B15UM and 3Z15UM based on identical electrical and mechanical parameters. All three parts share the same current rating (15A), voltage ratings (480V AC / 80V DC), breaker type (thermal magnetic), pole configuration (3-pole), mounting method (DIN rail), actuator design (lever), and regulatory approvals (CSA, UL508). The substitution logic is based strictly on these matching parameters, which define functional equivalence in circuit protection applications. Differences in part designation (C, B, Z) reflect manufacturer classification but do not alter electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3C15UM, 3B15UM, and 3Z15UM—are suitable for direct substitution based on identical electrical specifications and mechanical design. Selection among these equivalents may be determined by inventory availability. Current stock levels are: 3C15UM (991 pcs), 3B15UM (847 pcs), and 3Z15UM (741 pcs). All parts maintain active product status and carry full CSA and UL508 certifications, confirming compliance with industrial control standards. ROHS3 compliance and REACH unaffected status apply uniformly across all three options.

Frequently Asked Questions (FAQ)

Q: Can 3B15UM and 3Z15UM be used interchangeably with 3C15UM? A: Yes. All three parts share identical current ratings (15A), voltage ratings (480V AC / 80V DC), breaker type (thermal magnetic), pole configuration (3-pole), mounting method (DIN rail), and regulatory approvals (CSA, UL508). They are parametric equivalents.

Q: What determines substitution eligibility for these circuit breakers? A: Substitution is based on matching current rating, AC and DC voltage ratings, breaker type, number of poles, mounting type, actuator type, and approval certifications. All three parts meet these criteria.

Q: Are there any differences in packaging or form factor? A: All three parts are supplied in bulk packaging and are designed for DIN rail mounting with identical mechanical specifications.

Q: Do all substitute parts carry the same regulatory certifications? A: Yes. 3C15UM, 3B15UM, and 3Z15UM all carry CSA and UL508 approvals and are ROHS3 compliant with REACH unaffected status.

Q: Which part should be selected if all are available? A: Selection may be based on inventory availability or internal part numbering conventions. Electrical and mechanical performance are equivalent across all three options.
