Altech Corporation 2B5UM Circuit Breaker Equivalent & Substitute Parts
Part Overview
The 2B5UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted device is rated for 5A current with dual voltage capability (480V AC / 80V DC) and features a lever actuator for manual operation. The product is active and in stock with 1102 units available. Equivalent substitute parts exist within the same product family, sharing identical electrical and mechanical specifications, allowing for direct replacement in applications where component availability or supply chain requirements necessitate alternative part selection.

Engineering Selection Recommendations
All five parts (2B5UM, 2C5UM, 2D5UM, 2E5UM, 2G5UM) are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:
-
Regulatory Requirements: Parts 2C5UM and 2D5UM carry VDE certification in addition to CSA and UL508, providing broader European compliance coverage. Parts 2B5UM, 2E5UM, and 2G5UM carry CSA and UL508 certifications.
-
Inventory Availability: 2B5UM (1102 units), 2G5UM (1039 units), 2E5UM (1033 units), 2C5UM (983 units), and 2D5UM (850 units) are all in stock. Selection may be driven by supply chain lead time requirements or bulk order quantities.
-
Application Compliance: For applications requiring VDE certification, 2C5UM or 2D5UM are appropriate selections. For applications requiring only CSA and UL508 compliance, any of the five parts are suitable.
Frequently Asked Questions (FAQ)
Q: Can 2C5UM replace 2B5UM in my application? A: Yes. Both parts are identical in electrical rating (5A, 480V AC / 80V DC), breaker type (thermal magnetic), mounting (DIN rail), and mechanical configuration (2-pole lever actuator). The only difference is that 2C5UM includes VDE certification in addition to CSA and UL508.
Q: What is the difference between these substitute parts? A: All five parts share identical electrical and mechanical specifications. Differences exist only in manufacturer base product designation and regulatory certifications. Parts 2C5UM and 2D5UM include VDE approval; the others do not.
Q: Are all these parts DIN rail compatible? A: Yes. All five parts are DIN rail-mounted devices with identical mounting specifications and mechanical dimensions.
Q: Which part should I select if I need European compliance? A: Select 2C5UM or 2D5UM, as both carry VDE certification along with CSA and UL508 approvals.
Q: Can I mix these parts in the same installation? A: Yes. All parts are functionally and electrically identical, allowing mixed deployment in multi-breaker installations without performance or compatibility issues.
Q: What is the current availability of substitute parts? A: All five parts are in stock: 2B5UM (1102 units), 2G5UM (1039 units), 2E5UM (1033 units), 2C5UM (983 units), and 2D5UM (850 units).
