Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2E20UM are determined by equivalence across the following critical parameters: breaker type (thermal magnetic), current rating (20A), AC voltage rating (480V), DC voltage rating (80V), number of poles (2), mounting type (DIN Rail), actuator type (lever), and series classification (V-EA). All substitute parts maintain identical electrical performance characteristics and mechanical form factors, ensuring functional interchangeability within the specified operating envelope. Differences in approval agency certifications (CSA/UL508 versus CSA/UL508/VDE) do not affect substitution eligibility when the application requirements fall within the certified parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (2C20UM, 2D20UM, 2G20UM, 2Z20UM) are active products with identical electrical and mechanical specifications to the 2E20UM. Selection among these equivalents may be based on inventory availability and certification requirements. Parts 2C20UM and 2D20UM include VDE certification in addition to CSA and UL508 approvals, providing expanded compliance coverage for applications requiring European standards. Parts 2E20UM, 2G20UM, and 2Z20UM carry CSA and UL508 certifications. All parts comply with ROHS3 and REACH requirements, with ECCN classification EAR99 and HTSUS code 8536.20.0020.

Frequently Asked Questions (FAQ)

Q: Can 2C20UM, 2D20UM, 2G20UM, and 2Z20UM be used interchangeably with 2E20UM?

A: Yes. All parts share identical electrical ratings (20A, 480V AC, 80V DC), thermal magnetic protection characteristics, two-pole configuration, DIN Rail mounting, and lever actuation. They are parametric equivalents within the V-EA series.

Q: What is the difference between parts with CSA/UL508 certification and those with CSA/UL508/VDE certification?

A: Parts 2C20UM and 2D20UM include VDE certification, meeting European standards in addition to North American certifications. Parts 2E20UM, 2G20UM, and 2Z20UM carry CSA and UL508 certifications only. Certification selection depends on geographic application requirements and regulatory compliance needs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed (2E20UM, 2C20UM, 2D20UM, 2G20UM, 2Z20UM) are ROHS3 compliant and REACH unaffected.

Q: What packaging format is used for these circuit breakers?

A: All parts are supplied in bulk packaging.

Q: Which part has the highest current inventory availability?

A: 2D20UM has the highest inventory at 1148 pieces, followed by 2G20UM at 1118 pieces and 2E20UM at 1137 pieces.
