HOW TO ORDER:

Designate the Model Number and the three-digit dash number
from Table 3  to define the configuration desired.

Model numbers ending in 200 series include memory to replicate the decaying reset characteristic of electro-mechanical
relay disks even while the input current is zero. Model numbers ending in 100 series reset instantaneously (regardless
of settings) when the input current drops below the minimum TOC pickup value.
