A continuous green light signals that the device is working correctly.
A continuous red light signals a ground-fault tripping.
A continuous red light signals an active thermistor trip.
A continuous red light signals an active overload trip; a flickering red
light signals an imminent trip (overload warning).
Setting the device to the motor current and to the required trip class
dependent on the start-up conditions is easy with the two rotary
switches.
With this switch you can choose between manual and automatic
RESET.
Enables testing of all important device components and functions,
plus resetting of the device after a trip when manual RESET is select-
ed.
The generously sized terminals permit connection of two conductors
with different cross-sections for the auxiliary, control and sensor cir-
cuits. Connection is possible with screw connection and alternatively
with spring-type connection.
Enables more functions to be added, e.g. internal ground fault detec-
tion and/or an analog output with corresponding signals.
Overload Relays

The modular, solid-state overload relays with external power
supply type 3RB22 (with monostable auxiliary contacts) and
type 3RB23 (with bistable auxiliary contacts) up to 630 A (up to
820 A possible with a series transformer) have been designed
for inverse-time delayed protection of loads with normal and
heavy starting
ature rises due to overload, phase unbalance or phase failure.
An overload, phase unbalance or phase failure result in an in-
crease of the motor current beyond the set motor rated current.
This current rise is detected by means of a current measuring
module and electronically evaluated by a special evaluation
module which is connected to it. The evaluation electronics
sends a signal to the auxiliary contacts. The auxiliary contacts
then switch off the load by means of a contactor. The break time
depends on the ratio between the tripping current and set cur-
rent I
characteristic
status is signaled by means of a continuous red "
LED.
The LED indicates imminent tripping of the relay due to overload,
phase unbalance or phase failure by flickering when the limit
current has been violated. This warning can also issued as a sig-
nal through auxiliary contacts.
In addition to the described inverse-time delayed protection of
loads against excessive temperature rises, the 3RB22/3RB23
solid-state overload relays also allow direct temperature moni-
toring of the motor windings (full motor protection) by connection
with short-circuit and open-circuit detection of a PTC sensor cir-
cuit. With this temperature-dependent protection, the loads can
be protected against overheating caused indirectly by reduced
coolant flow, for example, which cannot be detected by means
of the current alone. In the event of overheating, the devices
switch off the contactor, and thus the load, by means of the aux-
iliary contacts. The "tripped" status is signaled by means of a
continuously illuminated "
To also protect the loads against high-resistance short-circuits
due to damage to the insulation, humidity, condensed water,
etc., the 3RB22/3RB23 solid-state overload relays offer the pos-
sibility of internal ground fault monitoring in conjunction with a
function expansion module
ing
Wye-Delta starting). In the event of a ground fault the 3RB22/
3RB23 relays trip instantaneously. The "tripped" status is sig-
naled by means of a continuous red "GND Fault" LED. Signaling
through auxiliary contacts is also possible.
After tripping due to overload, phase unbalance, phase failure,
thermistor tripping or ground fault, the relay is reset manually or
automatically after the recovery time has elapsed
(see, LV 1 T
In conjunction with a function expansion module the motor cur-
rent measured by the microprocessor can be output in the form
of an analog signal 4 ... 20 mA DC for operating rotary coil in-
struments or for feeding into analog inputs of programmable
logic controllers. With an additional AS-Interface analog module
the current values can also be transferred over the AS-i bus
system.
The devices are manufactured in accordance with environmen-
tal guidelines and contain environmentally friendly and reusable
materials.
They comply with all important worldwide standards and ap-
provals.
