Equivalent & Substitute Parts for ME2-B-94-430-1-A37-B-C

Part Overview

The ME2-B-94-430-1-A37-B-C is a circuit breaker manufactured by Carling Technologies, classified as a magnetic (hydraulic delay) type with a 3A current rating and dual voltage capability (250 V AC / 80 V DC). This component is designed for panel mount applications with rocker actuator operation and serves as an overcurrent protection device in electrical systems. The part maintains Active product status with 865 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability, supply chain considerations, or design standardization across manufacturing platforms.

Substitute Part Grouping Explanation

Substitute parts for the ME2-B-94-430-1-A37-B-C are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Breaker Type: Magnetic (Hydraulic Delay) operation must be identical
• Current Rating: 3A specification must be maintained
• Voltage Ratings: Both 250 V AC and 80 V DC ratings must be supported
• Mounting Configuration: Panel mount requirement must be satisfied
• Actuator Type: Rocker actuator operation must be preserved
• Pole Configuration: 2-pole design must be maintained
• Illumination Status: No illumination feature in all equivalent parts

Both identified substitute parts (IEGBX66-1-52-3.00-A-M3-V and IEGF6-40153-073-V) from Sensata-Airpax meet all specified parameters and are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three circuit breaker models maintain Active product status and are compliant with applicable regulatory frameworks. The ME2-B-94-430-1-A37-B-C carries approvals from CCC, CSA, and UL1077. Both substitute parts from Sensata-Airpax carry CSA, TUV, and UL1077approvals, with TUV certification providing additional international compliance coverage.

From a compliance perspective, the substitute parts satisfy the same electrical safety standards (UL1077) and CSA requirements. The Sensata-Airpax components include TUV certification, which extends compliance recognition across European markets. Both substitute parts are RoHS compliant and share identical ECCN and HTSUS classifications with the original part.

Inventory availability differs across the three options: the original Carling part has 865 units in stock, while IEGBX66-1-52-3.00-A-M3-V has 674 units and IEGF6-40153-073-V has 749 units available. Selection between substitute parts should be based on specific supply chain requirements and design platform standardization objectives.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must remain constant when substituting the ME2-B-94-430-1-A37-B-C?

A: The current rating (3A), AC voltage rating (250 V), DC voltage rating (80 V), breaker type (magnetic with hydraulic delay), and pole configuration (2-pole) must all remain unchanged. Any deviation from these parameters disqualifies a part as an equivalent substitute.

Q: Are the Sensata-Airpax substitute parts mechanically compatible with the original Carling part?

A: Both substitute parts share identical mounting type (panel mount), actuator type (rocker), and pole configuration (2-pole) with the original part. These mechanical parameters ensure functional compatibility in panel mount applications.

Q: What is the difference between the two Sensata-Airpax substitute parts?

A: Both IEGBX66-1-52-3.00-A-M3-V and IEGF6-40153-073-V are parametric equivalents with identical electrical and mechanical specifications. They differ only in their base product numbers (IEGBX66 versus IEGF6) and internal design architecture. Selection between them depends on design platform standardization and supply chain preferences.

Q: Do the substitute parts carry the same certifications as the original part?

A: Both substitute parts carry CSA and UL1077 certifications, matching the original part's compliance requirements. The substitute parts additionally include TUV certification, which the original part does not list. All three parts are classified under the same ECCN (EAR99) and HTSUS (8536.20.0020) codes.

Q: Is illumination available on any of these circuit breaker models?

A: No. The original ME2-B-94-430-1-A37-B-C and both substitute parts are specified without illumination features. If illumination is required, alternative part numbers outside this equivalency group must be evaluated.

Q: What is the moisture sensitivity level of the substitute parts?

A: Both Sensata-Airpax substitute parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
