Key Parameters

Substitute Part Grouping Explanation

Substitution of the APL1-1-62-403 is determined by strict equivalence across the following critical parameters:

• Breaker Type: Magnetic (Hydraulic Delay) protection mechanism
• Current Rating: 40A
• Voltage Rating - AC: 277V minimum
• Mounting Type: Panel Mount configuration
• Actuator Type: Lever operation
• Number of Poles: Single-pole (1P)

The substitute part W91-X112-40 satisfies all these criteria. Both parts share identical functional specifications for current interruption, voltage withstand, and mechanical interface requirements. The substitute maintains compatibility with existing panel mount installations designed for the original APL1-1-62-403.

Frequently Asked Questions (FAQ)

Q: Can the W91-X112-40 directly replace the APL1-1-62-403 in existing installations?

A: Yes. Both parts are single-pole, 40A, 277V AC lever-actuated circuit breakers with magnetic-hydraulic delay protection and panel mount configuration. The electrical and mechanical interfaces are equivalent.

Q: What is the primary reason for substitution?

A: The APL1-1-62-403 is obsolete. The W91-X112-40 provides identical functionality with active manufacturing status and current compliance certifications.

Q: Are there differences in packaging between these parts?

A: The original part number does not specify packaging details. The substitute is supplied in Bulk packaging. Verify packaging requirements for your procurement process.

Q: Does the substitute meet modern regulatory requirements?

A: Yes. The W91-X112-40 is ROHS3 Compliant and REACH Affected, meeting current environmental directives. The original part status for these certifications is not specified.

Q: Are the DC voltage ratings equivalent?

A: The original part is rated for 65V DC. The substitute specification does not explicitly state a DC voltage rating. Confirm DC voltage requirements for your application before final selection.
