Device description

3ZX1012-0RB12-1AA1 11

English

Limited touch protection

Degree of protection in conformity with IEC 60529:

IP 20 for devices 70 mm

IP 00 for devices > 70 mm

Shock-proof in conformity with DIN VDE 0106, Part

100.

Installation and maintenance by technical personnel

only. Follow the operating instruction!

1 Device description

The 3RB12 electronic overload relay protects electrical

equipment, such as three-phase AC motors and trans-

formers, with three different protection mechanisms.

Overload

protection The 3RB12 compares the motor current actually

flowing with the set current and evaluates the values

in a microprocessor.

Thermistor

protection PTC thermistors in the motor windings sense the motor

temperature. If the thermistor responds, the relay trips.

Earth-fault

protection Versions with internal earth-fault detection are suitable

for service in three-wire systems.

Versions with earth-fault detection by means of an

external summation current transformer are suitable

for service in three-wire and four-wire systems.

WARNING

HAZARDOUS VOLTAGE

CAN CAUSE ELECTRICAL SHOCK

AND BURNS.

DISCONNECT POWER BEFORE PROCEEDING

WITH ANY WORK ON THIS EQUIPMENT.

For dimension drawings, see graphics section, Fig. I

and II.

Mounting position: any

Mounting of 70 mm devices:

■ Snap-on mounting on 35 mm mounting rail in con-

formity with EN 50 022 or

■ srew mounting by means of inserted lugs as

accessory (3RB1900-0B).

Mounting of the 120 mm, 145 mm und 230 mm

devices:

■ Crew mounting integrated in the casing.

■ In addition for 120 mm size:

Baseplate for snap-on fastening on 75 mm mount-

ing rail (3UF1900-0J) available as accessory.

3 Connection

3.1 Main conductor connection

3.1.1 Current range up to 100 A

■ Rated motor currents from 1.25 A to 100 A:

Insert the motor leads per phase through the open-

ings (x) in the unit (see graphics section, Fig. Ia).

■ Rated motor currents less than 1.25 A:

Insert the motor leads per phase through the open-

ings (x), take them back through the loop opening (y)

and insert them again through the openings (x). You

will produce two loops in this way (see graphics sec-

tion, Fig. Ia).

The following table lists the number of loops for the

various rated motor currents.
