2E2UM Thermal Magnetic Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2E2UM is a thermal magnetic circuit breaker rated for 2A at 480V AC and 80V DC, designed for DIN Rail mounting with lever actuation and dual-pole configuration. This component is Active in product status and carries CSA and UL508 approvals. Equivalent and substitute parts within the V-EA series maintain identical electrical and mechanical specifications, enabling direct replacement in applications requiring thermal magnetic protection at the specified current and voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution within this product family is determined by strict equivalence across the following critical parameters: current rating (2A), voltage ratings (480V AC / 80V DC), breaker type (thermal magnetic), mounting configuration (DIN Rail), actuator type (lever), and pole count (2). All substitute parts listed—2B2UM, 2C2UM, 2D2UM, and 2G2UM—maintain identical values for these parameters. Variations in part numbering reflect different thermal-magnetic trip characteristics or internal design variants within the V-EA series, not functional differences in the specified electrical and mechanical interface. All substitutes are Active products with ROHS3 compliance and REACH Unaffected status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (2B2UM, 2C2UM, 2D2UM, 2G2UM) are functionally equivalent to the 2E2UM for applications requiring 2A thermal magnetic circuit protection at 480V AC and 80V DC on DIN Rail installations. Selection among these equivalents may be based on approval requirements: 2C2UM and 2D2UM carry additional VDE certification beyond CSA and UL508. All parts maintain ROHS3 compliance and Active product status. Inventory availability ranges from 825 to 1151 pieces across the substitute group.

Frequently Asked Questions (FAQ)

Q: Can 2B2UM, 2C2UM, 2D2UM, or 2G2UM be used as direct replacements for 2E2UM?

A: Yes. All substitute parts share identical current rating (2A), voltage ratings (480V AC / 80V DC), breaker type (thermal magnetic), DIN Rail mounting, lever actuation, and dual-pole configuration. Direct mechanical and electrical substitution is supported.

Q: What is the difference between these part numbers if they have identical electrical specifications?

A: Part number variations reflect internal design or thermal-magnetic trip characteristic differences within the V-EA series. These differences do not affect compatibility with the specified electrical and mechanical interface requirements.

Q: Are there approval differences between the substitute parts?

A: 2C2UM and 2D2UM include VDE certification in addition to CSA and UL508. The remaining substitutes (2B2UM, 2G2UM) carry CSA and UL508 approvals. Selection should align with regional or application-specific certification requirements.

Q: Is RoHS compliance consistent across all substitutes?

A: Yes. All parts, including 2E2UM and all substitutes, are ROHS3 Compliant and REACH Unaffected.

Q: Can I mix these part numbers in the same installation?

A: Yes, provided the application requirements do not specify a particular approval agency or internal trip characteristic. All parts are electrically and mechanically interchangeable at the specified ratings.
