For overload relay for individual mounting, see Fig. ¡
Installation
For dimension drawings (dimensions in mm) see Fig. ¬
For permissible installed positions, see Fig. √
Snap>on mounting on a top>head rail (35 mm) to EN 50 022 or bolting on a
plane surface by two bolts to be secured by washers and spring washers.
Do not subject to sudden shocks or long>term vibrations.

For equipment circuit diagram, see Fig. ƒ
In the case of several single>phase loads, the three main circuits must be
connected in series.
Commissioning
For instructions, see Fig. ≈
— Set the scale to the rated current of load.
" Reset button (blue)
Push this button before commissioning and after tripping to make relay
ready for operation.
In the as>delivered condition, the auxiliary contact is set to H=Manual
resetting. To change from H=Manual to A=Automatic, press and turn
the button counter>clockwise from H to A.
" Test button (red)
When this button is actuated, the NC contact opens and the NO contact
closes, i.e. a test function for NC and NO contacts (simulation of over>
load tripping).
In the ∫Manual∫ position, the relay is reset when the blue button is
pressed.
In the ∫Automatic∫ position, the relay is reset automatically when the
red button is released.
' TRIPPED indication (green)
In the H setting, a green pin protrudes from the front plate to indicate
the TRIPPED condition. In the A setting, this condition is not indicated.

Tripping times are shown for a three>phase load from the cold state
(ambient temperature +20 ∞C). In the case of hot relays, preloaded with
1¥I , the tripping times decrease by approx. 25 %.

Technical data
Main circuit
Rated insulation voltage
Rated operational current
Permissible ambient air temperature
Suitable for use on a circuit capable of delivering not more than 5000 rms
symmetrical amperes, 600 V maximum.
For short>circuit protection
NH>, NEOZED or DIAZED fuses
According to excerpt from IEC 60947>4
DIN VDE 0660, Part 102
Type of coordination ∫1∫:
The contactor and overload relay may be damaged. If necessary, the
contactor and/or overload relay must be replaced.
Type of coordination ∫2∫:
The overload relay must not be damaged. However, contacts may be
welded as long as they can be easily separated.
