Double-pole power outputs PO3 and PO4 with trip circuit supervision in
power supply module
The power outputs PO3 and PO4 are double-pole normally open/form A power outputs
with trip circuit supervision.
When the two poles of the contacts are connected in series, they have the same technical
specification as PO1 for breaking duty. The trip circuit supervision hardware and
associated functionality which can supervise the breaker coil both during closing and
opening condition are also provided. Contacts PO3 and PO4 are almost always used for
energizing the breaker trip coils.
