The Siemens 3UA62 30 current
transformer operated bi-relays provide
accurate overload and accelerated
single phasing protection for three
phase motors having rated currents
upto 400A.
3UA62 30 comprise of current
transformer and a bimetallic tripping
unit. The tripping unit makes use
ofdual slider principal for faster
tripping under single phasing.

: 15 operations
per hour.
Selection (Setting Ranges)
Bi-relay are available in 5 different
ranges. The minimum and maximum
setting of each range is listed in table 1.
Short Circuit Protection
The bi-relay have to be protected from
short circuits. It is mandatory to use
back up HRC fuses. The maximum
permissible ratings of Siemens fuses as
per IS: 13947 pt-4 (Type 3NA1)
corresponding to type 2 co-ordination
for each relay range are listed in table
1. Maximum back-up fuse rating for
auxiliary circuit : 6 Amps.
Operating Instructions/Setting
Set scale so that ratio corresponds to
the rated load current.

details.
Installation
Bi-relays are independent mounting

type. Permitted mounting position is as
shown in fig. 1. Care should be taken to
avoid shocks and prolonged vibrations.
Bi-relays are suitable for screw
mounting on flat vertical surface. Use 2
nos M5 screw with plain and spring
washers.
Maximum tightening torque = 6.2 Nm.
Refer fig. 2 for dimensions.
