4.3 I>, I>>, I>>> – Phase Overcurrent Protection
The Phase Overcurrent modules I>, I>>, and I>>> cover overcurrent stages, that can be
set up (independently of each other) as the following protection functions:
• DEFT = IEEE C37.2 / ANSI 50 — Denite-Time overcurrent protection, non-directional•
Characteristic see ╚═▷ “11.2.1.1 DEFT – Denite Time-Overcurrent (I>, I>>, I>>>)”
• IEEE C37.2 / ANSI 51 — Inverse-Time overcurrent protection, non-directional•
Available characteristics see ╚═▷ “11.2.1 Characteristics (I>, I>>, I>>>)”
For general information about the concept of WIC1 protection functions, see ╚═▷
