IEGF6-0-SW-50.0-01-V Circuit Breaker Magnetic Hydraulic Delay

Part Overview

The IEGF6-0-SW-50.0-01-V is a single-pole circuit breaker with magnetic hydraulic delay protection, rated for 50A at 250V AC and 80V DC. This lever-actuated panel mount breaker is designed for overcurrent protection in industrial and commercial electrical systems. The part is currently active in production with 744 units in stock. Finding equivalent substitute parts may be necessary due to supply chain constraints, lead time requirements, or inventory availability across different distribution channels.

Key Parameters

Substitute Part Grouping Explanation

The substitute part IUG2-28780-1 qualifies as a parametric equivalent based on the following critical matching parameters:

• Current Rating: 50A (identical)
• Voltage Rating - AC: 250V (identical)
• Voltage Rating - DC: 80V (identical)
• Breaker Type: Magnetic (Hydraulic Delay) (identical)
• Number of Poles: 1 (identical)
• Actuator Type: Lever (identical)
• Mounting Type: Panel Mount (identical)
• RoHS Status: RoHS Compliant (identical)

Both parts are manufactured by Sensata-Airpax and share the same electrical protection characteristics, mechanical interface, and regulatory compliance profile. The primary difference is the series designation (IEG versus IUG) and packaging format.

Parameter Comparison

Engineering Selection Recommendations

Both the IEGF6-0-SW-50.0-01-V and IUG2-28780-1 are active production parts from Sensata-Airpax with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability: IUG2-28780-1 has higher current inventory (951 units versus 744 units)
• Certification Requirements: IEGF6-0-SW-50.0-01-V carries CSA and TUV approvals in addition to UL1077; IUG2-28780-1 carries UL1077 certification. Verify that UL1077 certification alone meets your application requirements
• Packaging: IEGF6-0-SW-50.0-01-V is supplied in standard packaging; IUG2-28780-1 is supplied in bulk packaging
• Series Compatibility: Confirm that your system design does not specify a particular series requirement (IEG versus IUG)

Both parts are RoHS compliant with MSL 1 rating and identical electrical performance characteristics.
