Type H 475
3-phased current metering relay
Measures on current with 3-phased current
metering transformers, type A74-.. ...
Measures if all 3-phase currents are within
set limits
Upper and lower limits separately adjustable
Output: 10 A SPDT relay

3-phase current metering re-
lay with separate setting of
upper and lower current level.
For DIN-rail mounting. Often
used where a certain applica-

tion such as a large mixer has
to be kept within a set current
value in order not to overload
the system.
