Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified as parametric equivalents when they match all critical electrical and mechanical parameters: 2A current rating, 480V AC / 125V DC voltage ratings, 2-pole configuration, thermal magnetic operation, lever actuation, and DIN rail mounting. Substitution is valid across manufacturers (Weidmüller and E-T-A) provided regulatory approvals cover the intended application. Series designation (MCB 1077, MCB 489, 4230-T) and base product numbers differ but do not affect functional compatibility for the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and meet RoHS compliance requirements. Weidmüller parts 2478080000, 2478830000, and 2480280000 share identical electrical specifications and regulatory approvals (CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, VDE) with the main part, with differences limited to series designation and base product number. E-T-A parts 4230-T120-K0CE-2A and 4230-T120-K0CU-2A provide equivalent functionality with CSA C22.2 No 235 and UL1077/UL489 approvals. Selection between Weidmüller MCB 1077 and MCB 489 series, or between E-T-A variants, depends on specific regulatory requirements for the end application and existing component standardization within the system design.

Frequently Asked Questions (FAQ)

Q: Can Weidmüller MCB 489 series parts substitute for MCB 1077 series? A: Yes. Both series share identical electrical parameters (2A, 480V AC / 125V DC, 2-pole, thermal magnetic, lever, DIN rail) and RoHS compliance. Series designation reflects internal design differences that do not affect functional compatibility for the specified ratings.

Q: Are E-T-A 4230-T parts fully compatible with Weidmüller parts? A: Yes, for applications requiring CSA C22.2 No 235 and UL1077/UL489 certification. All parts match the critical electrical and mechanical parameters. Verify that the end application's regulatory framework accepts E-T-A approvals before substitution.

Q: What is the difference between 4230-T120-K0CE-2A and 4230-T120-K0CU-2A? A: Both parts are electrically and mechanically identical at 2A, 480V AC / 125V DC with 2-pole DIN rail mounting. The suffix designations (CE vs. CU) reflect internal configuration or approval variants. Consult E-T-A documentation for application-specific differences.

Q: Can I mix Weidmüller and E-T-A breakers in the same panel? A: Yes, provided the system design and regulatory approvals permit cross-manufacturer components. All listed parts meet the same electrical specifications and RoHS requirements. Verify compliance with local electrical codes and equipment certification standards.

Q: Are there inventory considerations for substitution? A: Inventory levels vary: Weidmüller 2481000000 (1028 pcs), 2478830000 (1086 pcs), 2480280000 (1066 pcs), 2478080000 (889 pcs), E-T-A 4230-T120-K0CE-2A (971 pcs), and 4230-T120-K0CU-2A (960 pcs). Availability should not influence technical substitution decisions; select based on regulatory and design requirements.
