IAR1-1-52-50.0-AC-00 Equivalent & Substitute Parts

Part Overview

The IAR1-1-52-50.0-AC-00 is a single-pole circuit breaker with magnetic and hydraulic delay protection, rated for 50A at 250V AC and 80V DC. It features a lever-actuated panel mount design and is manufactured by Sensata-Airpax. The product is active and RoHS compliant. Equivalent substitute parts may be required due to inventory availability, supply chain considerations, or specific packaging requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The substitute part IUG2-28780-1 is classified as a parametric equivalent based on matching all critical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

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

The substitute part belongs to a different series (IUG versus IAR) but maintains functional and electrical equivalence through identical protection characteristics and ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the IAR1-1-52-50.0-AC-00 and IUG2-28780-1 are active products manufactured by Sensata-Airpax with identical electrical ratings and mechanical specifications. Selection between these parts should be based on:

• Availability and inventory status
• Packaging requirements (IAR1-1-52-50.0-AC-00 standard packaging versus IUG2-28780-1 bulk packaging)
• Supply chain lead times
• Series preference for design documentation or procurement standards

Both parts meet RoHS compliance requirements and carry identical ECCN and HTSUS classifications, making them suitable for equivalent substitution in applications requiring 50A single-pole magnetic-hydraulic circuit protection at 250V AC / 80V DC.

Frequently Asked Questions (FAQ)

Q: Can IUG2-28780-1 be used as a direct replacement for IAR1-1-52-50.0-AC-00?

A: Yes. Both parts are parametric equivalents with identical current ratings (50A), voltage ratings (250V AC / 80V DC), breaker type (magnetic with hydraulic delay), mounting configuration (panel mount lever), and pole count (1). They are functionally interchangeable in applications requiring these specifications.

Q: What is the difference between these two part numbers?

A: The primary differences are the series designation (IAR versus IUG) and packaging format. The IAR1-1-52-50.0-AC-00 uses standard packaging, while IUG2-28780-1 is supplied in bulk packaging. All electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS compliant, carry the same ECCN classification (EAR99), and share identical HTSUS codes (8536.20.0020). Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should I specify for new designs?

A: Either part is acceptable for new designs. Selection should be based on packaging requirements, inventory availability, and internal procurement standards. Both are active products with equivalent technical specifications.

Q: Does packaging affect electrical performance?

A: No. Packaging format (standard versus bulk) does not affect the electrical or mechanical performance of the circuit breaker. Selection should be based on supply chain and logistics requirements.
