Key Parameters

Substitute Part Grouping Explanation

The 2G4.6UM qualifies as a parametric equivalent to the 2B4.6UM based on strict alignment of all critical electrical and mechanical parameters. Both components share identical specifications across current rating (4.6A), AC voltage (480V), DC voltage (80V), breaker type (thermal magnetic), mounting configuration (DIN rail), actuator mechanism (lever), pole count (2), and regulatory approvals (CSA, UL508). The substitution is valid within the V-EA series where these parameters define functional interchangeability. The primary distinction between these parts is the base product designation (2B4.6 versus 2G4.6), which reflects internal product line differentiation within Altech Corporation's portfolio but does not alter electrical or mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 2B4.6UM and 2G4.6UM are Active products with identical regulatory compliance certifications (CSA, UL508) and environmental compliance status (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on availability and procurement lead time, as both components satisfy all specified electrical and mechanical requirements. The 2B4.6UM currently maintains higher inventory (1044 pcs) compared to the 2G4.6UM (757 pcs), which may influence supply chain decisions. Both parts are suitable for direct substitution in DIN rail-mounted thermal magnetic protection applications requiring 4.6A capacity at 480V AC or 80V DC.

Frequently Asked Questions (FAQ)

Q: Can the 2G4.6UM replace the 2B4.6UM in existing installations? A: Yes. Both components are parametric equivalents with identical electrical ratings (4.6A, 480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and regulatory approvals (CSA, UL508). Direct substitution is valid.

Q: What is the difference between the 2B4.6 and 2G4.6 base product numbers? A: The base product designation reflects internal product line categorization within Altech Corporation's V-EA series. This distinction does not affect electrical performance, mechanical compatibility, or functional characteristics.

Q: Are both parts compliant with current environmental regulations? A: Yes. Both the 2B4.6UM and 2G4.6UM are ROHS3 Compliant and REACH Unaffected, meeting current environmental standards for electronic components.

Q: What certifications apply to these circuit breakers? A: Both components carry CSA and UL508 approvals, qualifying them for use in certified electrical distribution and control systems.

Q: Is there a difference in packaging between these parts? A: Both components are supplied in Bulk packaging. No packaging differentiation exists between the 2B4.6UM and 2G4.6UM.
