Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2D50UM is determined by exact matching of the following critical parameters: current rating (50A), AC voltage rating (480V), DC voltage rating (60V), breaker type (thermal magnetic), mounting configuration (DIN rail), pole count (2), actuator mechanism (lever), and regulatory certifications (CSA, UL508). The 2G50UM meets all these requirements and belongs to the same V-EA series, making it a parametric equivalent. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability within the same application context.

Parameter Comparison

Engineering Selection Recommendations

Both the 2D50UM and 2G50UM are active products with full regulatory compliance under CSA and UL508 standards. Selection between these parts is based on availability and application requirements. The 2G50UM currently maintains higher inventory levels (1054 pcs) compared to the 2D50UM (710 pcs), making it suitable for high-volume procurement scenarios. Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring compatibility with environmental and regulatory requirements. No technical performance differentiation exists between these models; selection is driven by supply chain and inventory considerations.

Frequently Asked Questions (FAQ)

Q: Can the 2G50UM directly replace the 2D50UM in existing installations? A: Yes. Both parts are parametric equivalents with identical electrical ratings (50A, 480V AC, 60V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), pole count (2), and regulatory certifications (CSA, UL508). Direct substitution is supported without circuit modification.

Q: What are the critical parameters that define substitution eligibility? A: Current rating, AC and DC voltage ratings, breaker type, mounting type, number of poles, actuator type, and regulatory certifications must match exactly. The 2D50UM and 2G50UM satisfy all these criteria.

Q: Are there any compliance or certification differences between these parts? A: No. Both parts carry identical CSA and UL508 approvals, ROHS3 compliance status, and REACH unaffected designation. Regulatory requirements are fully satisfied by either part.

Q: What is the difference between the 2D50UM and 2G50UM model designations? A: The model designations reflect internal Altech Corporation product line differentiation. Both parts belong to the V-EA series and maintain identical functional and electrical specifications. The difference is administrative rather than technical.

Q: Can these parts be used interchangeably in the same panel or circuit? A: Yes. Identical DIN rail mounting, lever actuation, 2-pole configuration, and electrical ratings ensure full interchangeability within the same electrical distribution system.
