Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3Z10UM is determined by equivalence across the following critical parameters: current rating (10A), AC voltage rating (480V), DC voltage rating (80V), breaker type (thermal magnetic), mounting configuration (DIN rail), actuator mechanism (lever), and pole count (3). The 3C10UM meets all these requirements and is classified as a parametric equivalent. The primary distinction between the main part and substitute is the trip characteristic designation (Z-characteristic versus C-characteristic), which reflects different thermal-magnetic response curves suitable for specific load types. Both parts maintain identical electrical ratings, mechanical form factor, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 3Z10UM and 3C10UM are active products with full regulatory compliance. The 3Z10UM carries CSA and UL508 certifications, while the 3C10UM extends compliance to include VDE certification, providing broader international acceptance. Selection between these parts should be based on application-specific load characteristics and regional regulatory requirements. The 3C10UM offers enhanced certification coverage for applications requiring European standards compliance. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring environmental regulatory alignment. Inventory availability is confirmed for both components, supporting immediate procurement.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 3Z10UM and 3C10UM?

A: Both parts are electrically and mechanically identical with matching current ratings (10A), voltage ratings (480V AC / 80V DC), and DIN rail mounting specifications. The designation difference (Z-characteristic versus C-characteristic) indicates different thermal-magnetic trip curves optimized for specific load profiles. The 3C10UM includes additional VDE certification beyond the CSA and UL508 certifications of the 3Z10UM.

Q: Can the 3C10UM be used as a direct replacement for the 3Z10UM?

A: Yes, the 3C10UM is a parametric equivalent substitute. Both parts share identical electrical specifications, mechanical form factor, pole count, and mounting configuration. Selection should account for application load characteristics and regional certification requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both the 3Z10UM and 3C10UM are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory standards.

Q: What certifications does each part carry?

A: The 3Z10UM holds CSA and UL508 certifications. The 3C10UM holds CSA, UL508, and VDE certifications, providing expanded international regulatory acceptance.

Q: Is inventory available for both parts?

A: Yes, both parts are in active production status with confirmed inventory: 3Z10UM has 935 pieces available, and 3C10UM has 997 pieces available.
