Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LEL1-27350-3 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Parameters:

• Voltage Rating - AC: 415 V
• Voltage Rating - DC: 80 V
• Breaker Type: Magnetic (Hydraulic Delay)

Mechanical Compatibility Parameters:

• Number of Poles: 1
• Actuator Type: Lever
• Mounting Type: Panel Mount

Compliance Parameters:

• RoHS Status: RoHS Compliant
• Product Status: Active

Two substitute parts meet all specified parameters and are classified as parametric equivalents: IULK2-9433-3 from the IUL series and LELB1-1REC4-39500-10-V from the LELB series. Both maintain identical electrical ratings, mechanical configuration, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LEL1-27350-3, IULK2-9433-3, and LELB1-1REC4-39500-10-V—are manufactured by Sensata-Airpax and maintain active product status. Each part is RoHS compliant and carries identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, packaging requirements (LELB1-1REC4-39500-10-V is supplied in bulk packaging), or series preference within the LEL or IUL product families. All three parts are suitable for direct substitution in 415 V AC / 80 V DC single-pole lever-actuated panel mount circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can IULK2-9433-3 directly replace LEL1-27350-3? A: Yes. Both parts share identical electrical ratings (415 V AC, 80 V DC), breaker type (magnetic-hydraulic delay), mechanical configuration (single-pole, lever actuator, panel mount), and compliance status (RoHS compliant, active product).

Q: What is the difference between LEL1-27350-3 and LELB1-1REC4-39500-10-V? A: Both parts are electrically and mechanically equivalent. The primary difference is packaging: LELB1-1REC4-39500-10-V is supplied in bulk packaging, while LEL1-27350-3 uses standard packaging. Functional performance and specifications are identical.

Q: Are all substitute parts from the same manufacturer? A: Yes. LEL1-27350-3, IULK2-9433-3, and LELB1-1REC4-39500-10-V are all manufactured by Sensata-Airpax.

Q: What parameters must match for a part to be considered a substitute? A: Critical matching parameters include voltage ratings (415 V AC, 80 V DC), breaker type (magnetic-hydraulic delay), number of poles (1), actuator type (lever), mounting type (panel mount), and compliance status (RoHS compliant, active product).

Q: Can these parts be used in applications rated for different voltages? A: No. These parts are specifically rated for 415 V AC and 80 V DC operation. Use only in applications matching these voltage specifications.
