Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019926 be used as a direct replacement for the 1019990?

A: Yes. Both parts are identical across all electrical and mechanical parameters, including current rating, voltage ratings, breaker type, mounting configuration, and pole count. Direct substitution is supported.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical RoHS3 compliance status and REACH unaffected designation. No compliance differentiation exists.

Q: What determines whether a part qualifies as a substitute for the 1019990?

A: A substitute must match all critical parameters: 50A current rating, 277V AC and 60V DC voltage ratings, thermal magnetic breaker type, DIN rail mounting, single-pole configuration, and lever actuation within the TMC 7 series.

Q: Does packaging affect substitution eligibility?

A: Packaging format (Box) is consistent across both parts and does not affect electrical or mechanical compatibility. Substitution remains valid regardless of packaging configuration.
