MN2-A-03-615-1-4FE-B-C Circuit Breaker Equivalent & Substitute Parts

Part Overview

The MN2-A-03-615-1-4FE-B-C is an active-status circuit breaker switch manufactured by Carling Technologies. This panel-mount device operates as a switch-only breaker rated for 15A at 250V AC and 80V DC, featuring a lever actuator and dual-pole configuration. The part is ROHS3 compliant and holds approvals from CCC, CSA, and UL1077. Substitute parts become necessary when original inventory is unavailable, when alternative breaker technologies offer operational advantages, or when supply chain requirements necessitate qualified alternatives meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MN2-A-03-615-1-4FE-B-C is determined by matching the following critical parameters: current rating of 15A, AC voltage rating of 250V, DC voltage rating of 80V, panel-mount configuration, lever actuator, and dual-pole design. Both substitute parts listed maintain these electrical and mechanical specifications. The primary distinction between the main part and substitutes is breaker technology: the MN2-A-03-615-1-4FE-B-C operates as a switch-only breaker, while the qualified substitutes employ magnetic-hydraulic delay technology. This technology difference does not affect substitution eligibility when electrical ratings and physical mounting requirements are identical. All substitute parts maintain the same HTSUS classification (8536.20.0020) and ECCN designation (EAR99), confirming functional equivalence within the circuit protection category.

Parameter Comparison

Engineering Selection Recommendations

All three circuit breaker options maintain active product status and share identical electrical ratings (15A, 250V AC, 80V DC) with matching mechanical configurations (panel mount, lever actuator, dual-pole). The MN2-A-03-615-1-4FE-B-C holds CCC, CSA, and UL1077 certifications. Both substitute parts carry UL1077 certification, with IELHK11-1-72-15.0-01-V providing additional RoHS compliance documentation and MSL rating of 1 (Unlimited). IUGH11-1-65-9.00-01 similarly maintains RoHS compliance and MSL 1 rating. Selection between these parts should be based on design requirements specific to breaker technology (switch-only versus magnetic-hydraulic delay), inventory availability, and certification requirements for the target application. All three parts are classified under identical HTSUS and ECCN codes, confirming regulatory equivalence for export and import purposes.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution of the MN2-A-03-615-1-4FE-B-C?

A: The substitute part must maintain a current rating of 15A, AC voltage rating of 250V, DC voltage rating of 80V, panel-mount configuration, lever actuator, and dual-pole design. Both listed substitutes meet these requirements.

Q: Does the difference between switch-only and magnetic-hydraulic delay breaker technology affect substitution eligibility?

A: No. When all electrical ratings and mechanical mounting specifications are identical, breaker technology type does not prevent substitution. The choice between technologies depends on application-specific protection requirements, not substitution compatibility.

Q: Are the substitute parts certified to the same standards as the main part?

A: Both substitutes carry UL1077 certification. The main part additionally holds CCC and CSA certifications. All three parts maintain EAR99 ECCN classification and 8536.20.0020 HTSUS code.

Q: What is the significance of the RoHS and MSL ratings on the substitute parts?

A: IELHK11-1-72-15.0-01-V and IUGH11-1-65-9.00-01 both carry RoHS compliance and MSL 1 (Unlimited) ratings, indicating environmental compliance and unlimited shelf-life storage capability. The main part is ROHS3 compliant, confirming equivalent environmental standards.

Q: Can packaging differences affect the substitution decision?

A: Packaging format (bulk versus other configurations) does not affect electrical or mechanical compatibility. Packaging selection should be based on procurement quantity requirements and inventory management practices.

Q: Are all three parts currently available?

A: All three parts maintain active product status. The MN2-A-03-615-1-4FE-B-C has 974 units in stock, IELHK11-1-72-15.0-01-V has 627 units, and IUGH11-1-65-9.00-01 has 879 units available as new original inventory.
