Frequently Asked Questions (FAQ)

Q: Can the W91-X112-3 directly replace the APL1-1-62-302 in existing installations?

A: Yes. Both parts are single-pole, 3A, 277V AC lever-actuated panel mount circuit breakers with magnetic hydraulic delay protection. Electrical and mechanical specifications are identical, permitting direct substitution.

Q: What is the primary reason for substitution?

A: The APL1-1-62-302 is obsolete. The W91-X112-3 is an active product offering equivalent protection characteristics with current manufacturing support.

Q: Are there packaging differences between these parts?

A: The APL1-1-62-302 is packaged as individual units. The W91-X112-3 is supplied in trays. Packaging format does not affect electrical or mechanical compatibility.

Q: Does the W91-X112-3 meet current compliance standards?

A: The W91-X112-3 is RoHS3 compliant and REACH affected, reflecting current regulatory requirements. The APL1-1-62-302 is REACH unaffected due to its obsolete status.

Q: Are the DC voltage ratings equivalent?

A: The APL1-1-62-302 is rated for 65V DC. The W91-X112-3 specification does not explicitly state a DC voltage rating in the provided data. Verify DC application requirements against the W91-X112-3 datasheet for DC-specific installations.
