TECHNICAL DATA
DESCRIPTION
● Ensuring continuity of supply to a single-
phase load,
● three-phase supply L1-L2-L3 (L1-priority
phase),
● adjustment of the response threshold for
maximum voltage,
● adjustment of the response threshold for
minimum voltage,
● adjustment of the priority phase reset time,
● adjustment of the auto reset time,

phases - 3 x LEDs,
● fault indication,
● mounting in the switchgear (DIN-Rail).
APM-10 Automatic phase switch is a de-
vice designed to maintain continuity of power
supply to a single-phase load at the time of
voltage fluctuation in the network. The device
automatically selects the closest priority phase
within the user-defined setting range and con-
nects it to the single-phase load. The maxi-
mum load capacity of the output should not
exceed 16A for loads in class AC1. APM-10 is
designed for installations in switchgears (DIN-
Rail). The housing has the width of 2 modules.

The device should be con-
nected to a one-phase network
in accordance with legally bind-
ing standards. The connection
method is described in this
manual. Any activities related
to installation, connection, and adjustment
should be performed by qualified electricians
who have read this user’s manual and famil-
iarised themselves with device functions. Re-
moving the enclosure voids the warranty and
poses a risk of electric shock. Before instal-
lation, make sure that there is no voltage on
connection cables. To install the device, use
a cross-head screwdriver with a diameter of
3.5 mm. The proper operation of the device
is affected by how the device is transported,
stored, and used. It is not advisable to install
the device in the following cases: lack of any
components, damage to or deformation of
the device. If the device operates improperly,
please contact the manufacturer.
NOTE
Do not dispose of this device together
with other waste! To avoid harmful effects
on the environment and human health,
the worn-out device should be stored
in designated areas. Electrical waste
from households may be handed over
to the waste collector established for
this purpose free of change and in any
amount, as well as to the store when
purchasing new equipment.
