Equivalent & Substitute Parts for LELB1-1REC4-39655-100-V

Part Overview

The LELB1-1REC4-39655-100-V is a single-pole circuit breaker with magnetic hydraulic delay protection, rated for 415 V AC and 80 V DC operation. Manufactured by Sensata-Airpax, this lever-actuated panel mount breaker is designed for industrial electrical protection applications. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts may be required due to inventory constraints, packaging preferences, or series standardization across equipment platforms.

Substitute Part Grouping Explanation

Substitution eligibility for the LELB1-1REC4-39655-100-V is determined by strict equivalence across the following parameters: breaker type (magnetic hydraulic delay), voltage ratings (415 V AC / 80 V DC), mounting configuration (panel mount), actuator mechanism (lever), pole count (single pole), and regulatory compliance (RoHS). Two substitute parts meet these criteria. The first substitute, LELB1-1REC4-39500-10-V, belongs to the same LEL series and maintains identical electrical and mechanical specifications with variation only in packaging format. The second substitute, IULK2-9433-3, represents a cross-series equivalent from the IUL product line, offering functional parity across all critical parameters while providing alternative sourcing within the Sensata-Airpax portfolio.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full RoHS compliance, qualifying them for equivalent application in 415 V AC / 80 V DC single-pole circuit protection circuits. LELB1-1REC4-39500-10-V provides same-series continuity with identical electrical performance and differs only in bulk packaging format. IULK2-9433-3 offers cross-series sourcing flexibility while maintaining functional equivalence across all specified electrical and mechanical parameters. Selection between these options depends on packaging requirements and inventory availability rather than technical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can LELB1-1REC4-39500-10-V be used as a direct replacement for LELB1-1REC4-39655-100-V?

A: Yes. Both parts share identical electrical ratings (415 V AC / 80 V DC), breaker type (magnetic hydraulic delay), mounting configuration (panel mount), and actuator mechanism (lever). The only difference is packaging format (bulk versus standard).

Q: What is the functional difference between LEL and IUL series breakers?

A: No functional difference exists for the specified parameters. Both series provide equivalent magnetic hydraulic delay circuit protection at 415 V AC / 80 V DC with single-pole lever-actuated panel mount configuration. Series designation reflects product line organization within the Sensata-Airpax portfolio.

Q: Are all three parts RoHS compliant?

A: Yes. LELB1-1REC4-39655-100-V, LELB1-1REC4-39500-10-V, and IULK2-9433-3 all carry RoHS Compliant certification.

Q: Does packaging format affect electrical performance?

A: No. Bulk packaging for LELB1-1REC4-39500-10-V provides identical component performance to standard packaging. Packaging selection is a procurement consideration only.

Q: Can these breakers operate at both 415 V AC and 80 V DC simultaneously?

A: The voltage ratings indicate maximum operating specifications for each respective current type. Application requirements determine whether AC, DC, or mixed-voltage operation is applicable.
