2G05UM Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2G05UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is rated for 500mA with dual-pole configuration and operates across 480V AC and 80V DC. The product is active and maintains CSA and UL508 certifications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2G05UM are identified based on matching the following critical parameters: thermal magnetic breaker type, 500mA current rating, 480V AC and 80V DC voltage ratings, DIN rail mounting, lever actuator, and 2-pole configuration. All substitute parts maintain the same series designation (V-EA) and comply with CSA and UL508 certifications. The substitutes differ only in base product designation (2D05 and 2E05 versus 2G05), which reflects internal manufacturer product line variations while preserving all functional and electrical characteristics required for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2G05UM, 2D05UM, and 2E05UM—are active products with identical electrical and mechanical specifications. Selection between these parts should be based on availability and regulatory requirements specific to the application region. The 2D05UM carries additional VDE certification beyond CSA and UL508, making it suitable for applications requiring European compliance. All parts maintain ROHS3 compliance and REACH unaffected status, ensuring environmental regulatory alignment. Inventory levels vary: 2G05UM (773 pcs), 2D05UM (676 pcs), and 2E05UM (1145 pcs), which may influence sourcing decisions based on lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can 2D05UM or 2E05UM be used as direct replacements for 2G05UM? A: Yes. All three parts share identical electrical ratings (500mA, 480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and pole count (2-pole). They are functionally interchangeable for applications requiring these specifications.

Q: What is the difference between these substitute parts? A: The parts differ only in base product designation and certification scope. 2D05UM includes VDE certification in addition to CSA and UL508. All other parameters—current rating, voltage ratings, mounting type, actuator type, and pole configuration—are identical.

Q: Are there any compatibility concerns when substituting these parts? A: No compatibility concerns exist when substituting between these parts. All maintain the same DIN rail mounting interface, lever actuator design, and electrical specifications. Physical dimensions and terminal configurations are consistent across the series.

Q: Which part should be selected for European applications? A: The 2D05UM is recommended for European applications due to its VDE certification, which supplements CSA and UL508 approvals.

Q: Do all substitute parts meet the same environmental compliance standards? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.
