LELK1-1-51-32.0-01-V Circuit Breaker Magnetic Hydraulic Delay Equivalent & Substitute Parts

Part Overview

The LELK1-1-51-32.0-01-V is a single-pole circuit breaker with magnetic hydraulic delay protection, rated for 30A at 415V AC and 80V DC. Manufactured by Sensata-Airpax, this lever-actuated panel mount breaker is designed for industrial electrical protection applications. The part is active in production with RoHS compliance and MSL Level 1 rating. Alternative part numbers may be required due to inventory availability, packaging specifications, or series preference within the LEL and IEL product families.

Substitute Part Grouping Explanation

Substitute parts for the LELK1-1-51-32.0-01-V are qualified based on identical electrical and mechanical parameters:

• Current Rating: 30A (exact match required)
• Voltage Rating - AC: 415V (exact match required)
• Voltage Rating - DC: 80V (exact match required)
• Breaker Type: Magnetic (Hydraulic Delay) (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)
• Manufacturer: Sensata-Airpax (same manufacturer family)
• RoHS Status: RoHS Compliant (compliance maintained)
• MSL Rating: 1 (Unlimited) (same rating maintained)

All substitute parts maintain these critical parameters. Variations in series designation (LEL vs. IEL) and packaging configuration do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full RoHS compliance. Selection between LELK1-1-51-32.0-01-V, IELK1-1-52-30.0-91-V, IELK1-1-63-30.0-01-V, and LELK1-1-72-50.0-01-V is determined by packaging requirements and series availability:

• LELK1-1-51-32.0-01-V: Original specification, standard packaging
• IELK1-1-52-30.0-91-V: IEL series alternative, bulk packaging
• IELK1-1-63-30.0-01-V: IEL series alternative, standard packaging
• LELK1-1-72-50.0-01-V: LEL series alternative, bulk packaging

All parts carry identical electrical ratings, mechanical interfaces, and regulatory certifications. Part selection should be based on procurement requirements and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Are all listed parts electrically interchangeable with the LELK1-1-51-32.0-01-V?

A: Yes. All substitute parts share identical current ratings (30A), AC voltage rating (415V), DC voltage rating (80V), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), and actuator type (Lever). Electrical performance and circuit protection characteristics are equivalent.

Q: What is the difference between LEL and IEL series designations?

A: Series designation indicates product family classification within the Sensata-Airpax portfolio. Both LEL and IEL series maintain identical electrical and mechanical specifications for this application. Series selection is based on procurement availability and internal product line management.

Q: Does packaging type affect compatibility?

A: No. Packaging differences (standard vs. bulk) do not affect the electrical or mechanical performance of the circuit breaker. Packaging selection is determined by procurement volume and logistics requirements.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts carry RoHS Compliant certification and MSL Level 1 (Unlimited) rating, meeting regulatory requirements for industrial applications.

Q: Can I use these parts interchangeably in existing installations?

A: Yes. All substitute parts are mechanically and electrically equivalent. Panel mount configuration, lever actuation, and single-pole design are identical across all listed part numbers.
