When using the overload relays with trip class ≥ CLASS 20, see Technical
Information LV 1 T "Technical specifications", "Short-Circuit Protection with
Fuses for Motor Feeders", and the project planning aid "Configuring SIRIUS Fuseless Load Feeders".
Connection methods
The 3RB20 and 3RB21 relays are available with screw terminals
(box terminals) or spring-loaded terminals on the auxiliary current side; the same applies for the evaluation modules of the
3RB22/3RB23 relays. The 3RU11 relays come with screw
terminals.

3RU1 Thermal Overload Relays
3RU11 for standard applications
"Increased safety" type of protection EEx e according to
ATEX directive 94/9/EC
■ Overview
3
The 3RU11 thermal overload relays are suitable for the overload
protection of explosion-proof motors with "increased safety" type
of protection EEx e. The relays meet the requirements of
EN 60079-7 (Electrical apparatus for areas subject to explosion
hazards – Increased safety "e");
see Chapter 20 "Appendix" --> "Standards and approvals" -->
"Type overview of approved devices for potentially explosive
areas (ATEX explosion protection)".

EC type test certificate for Category (2) G/D exists. It has the
number DMT 98 ATEX G 001.

■ Benefits
The most important features and benefits of the 3RU11 thermal
overload relays are listed in the overview table (see "Overload
Relays", --> "General data").
The 3RU11 thermal overload relays up to 100 A have been designed for inverse-time delayed protection of loads with normal
starting (see Technical Information LV 1 T, "Function") against excessive temperature rises due to overload or phase failure. An
overload or phase failure results in an increase of the motor current beyond the set rated motor current. Via heating elements,
this current rise heats up the bimetal strips inside the device
which then bend and as a result trigger the auxiliary contacts by
means of a tripping mechanism. 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 current
setting Ie and is stored in the form of a long-term stable tripping
characteristic (see Technical Information LV 1 T, "Characteristic
Curves").
■ Application
Industries
The 3RU11 thermal overload relays are suitable for customers
from all industries who want to guarantee optimum inverse-time
delayed protection of their electrical loads (e. g. motors) under
normal starting conditions (CLASS 10).
5
(1) Connection for mounting onto contactors:
Optimally adapted in electrical, mechanical and design terms to the
contactors, these connecting pins can be used for direct mounting of
the overload relays. Stand-alone installation is possible as an alternative (in some cases in conjunction with a stand-alone installation
module).
(2) Selector switch for manual/automatic RESET and RESET button:
With this switch you can choose between manual and automatic
RESET. A device set to manual RESET can be reset locally by pressing
the RESET button. A remote RESET is possible using the RESET modules (accessories), which are independent of size.
(3) Switch position indicator and TEST function of the wiring:
Indicates a trip and enables the wiring test.
(4) Motor current setting:
Setting the device to the rated motor current is easy with the large rotary knob.
(5) STOP button:
If the STOP button is pressed, the NC contact is opened. This switches
off the contactor downstream. The NC contact is closed again when
the button is released.
(6) Transparent, sealable cover:
Secures the motor current setting and the TEST function against
adjustment.
(7) Supply terminals:
The generously sized terminals permit connection of two conductors
with different cross-sections for the main and auxiliary circuits. The
auxiliary circuit can be connected with screw terminals and alternatively with spring-loaded terminals.
Application
The 3RU11 thermal overload relays have been designed for the
protection of three-phase and single-phase AC and DC motors.
If single-phase AC or DC loads are to be protected by the 3RU11
thermal overload relays, all three bimetal strips must be heated.
For this purpose, all main current paths of the relay must be connected in series.
Ambient conditions
The 3RU11 thermal overload relays have temperature compensation in accordance with IEC 60947-4-1 for the temperature
range of –20 to +60 °C. For temperatures from +60 to +80 °C the
upper set value of the setting range must be reduced by the factor listed in the table below.

value

1.0
+65
0.94
+70
0.87

The "tripped" status is signaled by means of a switch position indicator. Resetting takes place either manually or automatically
after a recovery time has elapsed (see Technical Information
LV 1 T, "Function").
The devices are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable
materials.
They comply with all important worldwide standards and
approvals.
