Substitute Part Grouping Explanation

The 3Z15UM circuit breaker has two parametric equivalents within the Altech Corporation V-EA series: 3B15UM and 3C15UM. Substitution eligibility is determined by matching the following critical parameters:

• Current Rating: 15A (all equivalents match)
• Voltage Rating - AC: 480V (all equivalents match)
• Voltage Rating - DC: 80V (all equivalents match)
• Breaker Type: Thermal Magnetic (all equivalents match)
• Number of Poles: 3 (all equivalents match)
• Mounting Type: DIN Rail (all equivalents match)
• Actuator Type: Lever (all equivalents match)
• Approval Agencies: CSA, UL508 (all equivalents match)
• RoHS Status: ROHS3 Compliant (all equivalents match)

All three parts share identical electrical and mechanical specifications, enabling direct substitution within the same application context.

Parameter Comparison

Engineering Selection Recommendations

All three circuit breaker models—3Z15UM, 3B15UM, and 3C15UM—are active products with identical electrical and mechanical specifications. Selection among these equivalents may be based on inventory availability. Current stock levels are: 3Z15UM (741 pcs), 3B15UM (847 pcs), and 3C15UM (991 pcs). All parts carry CSA and UL508 certifications and maintain ROHS3 compliance, ensuring regulatory conformance across all substitution options.

Frequently Asked Questions (FAQ)

Q: Can 3B15UM and 3C15UM be used as direct replacements for 3Z15UM?

A: Yes. All three parts share identical current ratings (15A), voltage ratings (480V AC / 80V DC), pole configuration (3-pole), mounting type (DIN Rail), actuator type (Lever), and regulatory certifications (CSA, UL508). Direct substitution is supported.

Q: Are there any differences in thermal or magnetic trip characteristics between these models?

A: No differences are specified in the provided parameters. All three models are classified as thermal magnetic breakers with identical electrical ratings.

Q: Do all substitute parts carry the same certifications?

A: Yes. 3Z15UM, 3B15UM, and 3C15UM all hold CSA and UL508 approvals and maintain ROHS3 compliance status.

Q: Is packaging identical across all three part numbers?

A: Yes. All three parts are supplied in bulk packaging.

Q: Can these breakers be used in both AC and DC applications?

A: Yes. All three models are rated for 480V AC and 80V DC operation, supporting both application types within their specified voltage ranges.
