Substitute Part Grouping Explanation

Substitution of the Weidmüller 991380 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 9913800003 qualifies as a direct parametric equivalent because it maintains identical specifications across the following critical criteria:

Current rating of 8A, voltage ratings of 480V AC and 65V DC, three-pole thermal magnetic configuration, lever actuation, DIN rail mounting, and CB2200 series classification. Both parts carry identical regulatory approvals (CSA C22.2 No 235, UL1077, VDE) and RoHS compliance status. The primary distinction is product status: the original part number is obsolete while the substitute is active, and packaging differs (original unspecified versus bulk for the substitute).

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 9913800003 is the direct substitute for the obsolete 991380 part number. Both components are manufactured by Weidmüller within the CB2200 series and share identical electrical ratings, mechanical configuration, and regulatory certifications. The substitute part maintains active product status with confirmed inventory availability (782 pcs), ensuring supply chain continuity. Selection of part number 9913800003 requires no design modifications, as all functional and compliance parameters remain unchanged. The bulk packaging of the substitute accommodates both single-unit replacement and larger procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 9913800003 directly replace the 991380 in existing installations?

A: Yes. Both parts are identical in electrical rating (8A, 480V AC, 65V DC), mechanical configuration (3-pole, lever-actuated, DIN rail mount), and regulatory approval (CSA C22.2 No 235, UL1077, VDE). No circuit modifications or recertification is required.

Q: What is the significance of the product status change from obsolete to active?

A: The original 991380 is no longer manufactured. The 9913800003 is the current production equivalent, ensuring long-term availability and supply chain reliability for replacement and new installations.

Q: Are there packaging considerations when ordering the substitute?

A: The substitute 9913800003 is supplied in bulk packaging, whereas the original packaging specification was not provided. Bulk packaging is standard for industrial circuit breaker distribution and does not affect component performance or installation.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the 991380 and 9913800003 are certified to CSA C22.2 No 235, UL1077, and VDE standards. RoHS compliance and REACH unaffected status are identical across both part numbers.

Q: Is there any difference in thermal magnetic trip characteristics between these parts?

A: No differences are specified in the provided parameters. Both parts are classified as thermal magnetic breakers with identical 8A current ratings and identical voltage specifications.
