• IEG6-1-72-20.0-01-V: CSA, TUV, UL1077
• IEL1-1-51-20.0-01-V: No approval agencies specified in data
• IELK1-1-72-20.0-01-V: UL1077
• IUG1-1-62-30.0-CQ-01: No approval agencies specified in data

All substitute parts maintain Active product status and RoHS compliance. Inventory availability ranges from 919 to 1212 pieces across substitute options, supporting procurement requirements.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for a part to substitute for the MM1-B-34-620-1-2DA-B-C?

A: The substitute part must maintain identical current rating (20A), AC voltage rating (250V), DC voltage rating (80V), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), actuator type (Lever), and pole count (1). All identified substitutes meet these requirements.

Q: Are all substitute parts panel mount configurations?

A: Yes. All substitute parts listed are panel mount, matching the main part specification.

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

A: Both IEG and IEL series parts are manufactured by Sensata-Airpax and meet identical electrical and mechanical parameters. The series designation reflects internal product line organization. Selection between series is based on availability and application-specific approval requirements.

Q: Do all substitute parts have the same approval certifications as the main part?

A: Substitute parts carry varying approval certifications. IEG1 and IEG6 include CSA, TUV, and UL1077. IELK1 includes UL1077. IEL1 and IUG1 do not specify approval agencies in available data. Applications requiring specific certifications should confirm compliance with the selected substitute part.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in Bulk packaging format, with the exception of IUG1-1-62-30.0-CQ-01, which does not specify packaging designation in available data.

Q: Can I use these substitute parts interchangeably in my application?

A: Yes. All substitute parts are parametrically equivalent to the main part across all critical electrical and mechanical specifications. Interchangeability is confirmed for applications requiring 20A, 250V AC, 80V DC magnetic hydraulic delay circuit breakers with lever panel mount actuation.

Q: What inventory levels are available for each substitute part?

A: Current inventory levels are as follows: IEG1-1-63-20.0-01-V (1051 pieces), IEG6-1-72-20.0-01-V (1032 pieces), IEL1-1-51-20.0-01-V (919 pieces), IELK1-1-72-20.0-01-V (1212 pieces), and IUG1-1-62-30.0-CQ-01 (1095 pieces).
