BV1 - Phase sequence relay
Application
Supervision of phase loss, phase sequence and
undervoltage in three-phase systems.
Function
Relay BV1 measures amplitude and angle of three
phase voltages. The angle of the phasors determine
the phase sequence. Unbalance and phase loss are
www.DataSheet4U.cdoemtected by the measurement of amplitude and angle.
The undervoltage trip setting is 70 % of Un fixed.
The underfrequency element trips if the frequency falls
below 45 Hz.

Fig. 1: Front plate
The unit BV1 is designed to be fastened onto a DIN-
rail acc. to DIN EN 50022 same as all units of the
BASIC LINE.
The front plate of the unit is protected with a sealable
transparent cover (IP40).
Please remove the transparent cover with a screw
driver to adjust the relay.
LED
LED is used to indicate operation without fault with
steady light. At tripping or underfrequency the LED
extinguishes.

Auxiliary voltage supply
The unit BV1 needs no separate auxiliary voltage
supply. The supply voltage can be formed directly from
the measuring quantity.

Connection terminals
The connection up to a maximum of 2 x 2,5 mm²
cross-section conductors is possible. For this procedure
the transparent cover of the unit has to be removed.
