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
inverse-time delayed protection of their electrical loads
(e.g. motors) under normal and heavy starting conditions
(CLASS 5 to CLASS 30), minimize project completion times,
inventories and power consumption, and optimize plant
availability and maintenance management.
Application
The 3RB20/3RB21 solid-state overload relays have been
designed for the protection of three-phase motors in sinusoidal
50/60 Hz voltage networks. The relays are not suitable for the
protection 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
changes.
For the temperature range from –25 C to +60 °C, the
3RB20/3RB21 solid-state overload relays compensate the
temperature according to IEC 60947-4-1.
Configuration notes for use of the devices below –25 °C or above
+60 °C on request.

"Increased safety" type of protection EEx e according to
ATEX guideline 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 guideline
94/9/EG 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 under
