Key Parameters

Substitute Part Grouping Explanation

Substitution of the LELBXPB111-1REC4-70014-175 is determined by strict equivalence across the following critical parameters:

Breaker Type (Magnetic Hydraulic Delay), Voltage Rating (415 V AC / 80 V DC), Number of Poles (3), Mounting Type (Panel Mount), and Actuator Type (Rocker). The substitute part LELBXK111-40826-30-V matches all these parameters exactly. Both parts are manufactured by Sensata-Airpax within the LEL series, share identical electrical and mechanical specifications, and maintain the same RoHS compliance and MSL rating. The difference in base product number (LELBXPB111 versus LELBXK111) reflects internal manufacturing or configuration variants that do not affect functional equivalence for this application.

Parameter Comparison

Engineering Selection Recommendations

Both the LELBXPB111-1REC4-70014-175 and LELBXK111-40826-30-V are active products manufactured by Sensata-Airpax with full RoHS compliance and MSL 1 rating. Selection between these parts should be based on inventory availability and procurement lead time. The LELBXPB111-1REC4-70014-175 has higher stock availability (1010 units) compared to the LELBXK111-40826-30-V (674 units). Both parts are functionally equivalent for applications requiring a three-pole magnetic hydraulic delay circuit breaker rated for 415 V AC and 80 V DC operation in panel mount configuration.

Frequently Asked Questions (FAQ)

Q: What makes LELBXK111-40826-30-V a valid substitute for LELBXPB111-1REC4-70014-175?

A: Both parts are manufactured by Sensata-Airpax within the LEL series and share identical electrical specifications (415 V AC, 80 V DC), mechanical configuration (three-pole rocker panel mount), protection type (magnetic hydraulic delay), and compliance certifications (RoHS compliant, MSL 1).
