Frequently Asked Questions (FAQ)

Q: Can IEG1-1-63-20.0-01-V be used as a direct replacement for MN1-B-34-620-1-2JB-B-C?

A: Yes. Both parts share identical electrical ratings (20A, 250V AC, 80V DC), breaker type (magnetic hydraulic delay), mounting configuration (panel mount), and actuator type (lever). Mechanical interface and functional performance are equivalent.

Q: What is the difference between the IEL and IEG series substitutes?

A: Both series are manufactured by Sensata-Airpax and meet identical electrical and mechanical specifications for this application. The series designation reflects internal product line organization. Functional equivalence is maintained across both series.

Q: Are there approval agency differences between substitutes?

A: Yes. IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V carry CSA, TUV, and UL1077 certifications. IELK1-1-72-20.0-01-V carries UL1077 certification. IEL1-1-51-20.0-01-V and IUG1-1-62-30.0-CQ-01 have no approval agencies specified in the provided data. Application requirements determine whether specific certifications are mandatory.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Packaging format (standard versus bulk) does not affect component performance. Packaging selection is determined by procurement and inventory management requirements.

Q: Are all substitutes currently in production?

A: Yes. All listed substitute parts maintain active product status.

Q: What is the HTSUS classification for these circuit breakers?

A: All parts, including the primary and substitute components, are classified under HTSUS 8536.20.0020.
