3RB2 Solid-State Overload Relays
3RB20, 3RB21 for standard applications
Application
Industries
The 3RB20/3RB21 solid-state overload relays are suitable for
customers from all industries who want to guarantee optimum in-
verse-time delayed protection of their electrical loads (e.g. mo-
tors) under normal and heavy starting conditions (CLASS 5 to
CLASS 30), minimize project completion times, inventories and
power consumption, and optimize plant availability and mainte-
nance management.
Application
The 3RB20/3RB21 solid-state overload relays have been de-
signed for the protection of induction motors in sinusoidal 50/60
Hz voltage networks. The relays are not suitable for the protec-
tion of single-phase AC or DC loads.
The 3RU11 thermal overload relay or the 3RB22/3RB23 solid-
state overload relay can be used for single-phase AC loads. For
DC loads we recommend the 3RU11 thermal overload relay.
Ambient conditions
The devices are insensitive to external influences such as
shocks, corrosive environments, ageing and temperature fluctu-
ation.
For the temperature range from –25 C to +60 °C, the
3RB20/3RB21 solid-state overload relays compensate the tem-
perature according to IEC 60947-4-1.
For the 3RB20/3RB21 solid-state overload relays with the sizes
S6, S10 and S12, the upper set value of the setting range must
be reduced for ambient temperatures > 50 °C by a certain factor
(see tables

"Increased safety" type of protection EEx e according to
ATEX directive 94/9/EC
The 3RB20/3RB21 solid-state overload relays are suitable for the
overload protection of explosion-proof motors with "increased
safety" type of protection EEx e. The relays meet the require-
ments of EN 60079-7 (Electrical apparatus for potentially explo-
sive atmospheres – Increased safety "e").
The basic safety and health requirements of ATEX directive
94/9/EC are fulfilled by compliance with
• EN 60947-1
• EN 60947-4-1
• EN 60947-5-1
• EN 60079-14
EU type test certificate for Group II, Category (2) G/D exists.
Accessories
The following accessories are available for the 3RB20/3RB21
solid-state overload relays:
• One terminal bracket each for the overload relays size S00
• One mechanical remote RESET module for all sizes
• One cable release for resetting devices which are difficult to
• One sealable cover for all sizes
• Box terminal blocks for sizes S6 and S10/S12
• Terminal covers for sizes S2 to S10/S12
and S0 (sizes S2 to S12 can be installed as single units without
a terminal bracket)
