MN1-B-20-620-1-1CB-B-C Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Carling Technologies MN1-B-20-620-1-1CB-B-C is a single-pole, magnetic hydraulic delay circuit breaker rated for 20A at 250V AC and 80V DC with lever panel mount actuation. This component is active in production and maintains full compliance with RoHS3 and REACH regulations. Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain optimization is required, or when design flexibility permits equivalent functionality from alternative manufacturers. All substitute parts listed maintain identical electrical and mechanical specifications to ensure direct functional replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MN1-B-20-620-1-1CB-B-C is determined by strict equivalence across the following parameters: breaker type (magnetic hydraulic delay), current rating (20A), AC voltage rating (250V), DC voltage rating (80V), mounting configuration (panel mount), actuator mechanism (lever), pole count (single pole), and absence of illumination. All substitute parts listed maintain these specifications without deviation. Substitutes are sourced from Sensata-Airpax, a qualified alternative manufacturer, and are grouped by series designation (IEG, IEL, IUG) while maintaining complete parametric alignment with the primary part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full RoHS compliance, ensuring regulatory alignment with the primary Carling Technologies component. The IEG series (IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V) carry CSA, TUV, and UL1077 certifications. The IEL series (IEL1-1-51-20.0-01-V and IELK1-1-72-20.0-01-V) provide UL1077 certification with IEL1-1-51-20.0-01-V offering no additional agency approvals and IELK1-1-72-20.0-01-V limited to UL1077. The IUG series (IUG1-1-62-30.0-CQ-01) provides no specified approval agencies. The primary part MN1-B-20-620-1-1CB-B-C carries CCC, CSA, and UL1077 certifications. Selection should prioritize substitute parts with certification alignment to the application requirements. All parts maintain Moisture Sensitivity Level 1 (Unlimited) where specified, indicating no moisture handling restrictions during storage or assembly.

Frequently Asked Questions (FAQ)

Q: What determines if a circuit breaker can substitute for the MN1-B-20-620-1-1CB-B-C?

A: Direct substitution requires matching specifications across all critical parameters: 20A current rating, 250V AC and 80V DC voltage ratings, magnetic hydraulic delay breaker type, single-pole configuration, lever actuator, panel mount installation, and absence of illumination. All listed substitute parts meet these requirements.

Q: Are there differences in approval certifications between the main part and substitutes?

A: Yes. The primary part carries CCC, CSA, and UL1077 certifications. Substitute parts vary: IEG series includes CSA, TUV, and UL1077; IEL1-1-51-20.0-01-V carries no specified approvals; IELK1-1-72-20.0-01-V carries UL1077 only; IUG1-1-62-30.0-CQ-01 carries no specified approvals. Application requirements should guide certification selection.

Q: What is the inventory status of substitute parts?

A: All substitute parts are in active production with current stock availability: IEG1-1-63-20.0-01-V (1051 pcs), IEG6-1-72-20.0-01-V (1032 pcs), IEL1-1-51-20.0-01-V (919 pcs), IELK1-1-72-20.0-01-V (1212 pcs), and IUG1-1-62-30.0-CQ-01 (1095 pcs).

Q: Do substitute parts have different packaging requirements?

A: The primary part specifies standard packaging. Substitute parts are supplied in bulk packaging, which may affect procurement and handling procedures. Confirm packaging compatibility with assembly and logistics workflows.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part is RoHS3 compliant. All substitute parts are RoHS compliant. Both designations meet current environmental regulations.

Q: What is the Moisture Sensitivity Level for substitute parts?

A: Substitute parts with specified MSL ratings carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can substitute parts be used interchangeably in existing designs?

A: All substitute parts maintain identical electrical and mechanical specifications to the primary part. Physical form factor and mounting interface compatibility should be confirmed with mechanical drawings before implementation in existing designs.
