RW-E
The new RW_E Solid State Overload relays are developed with
cutting edge technology according to the most demanding
standards worldwide� With its wide current/AMP setting; the
RW_E OL Relay can be used for protection of electric motors of
different power ratings� The benefit is versatility and flexibility
for manufacturers due to the possibility of standardization of
control panels� This Solid State Overload Relay can be directly
mounted on WEG Contactors (CWM and CWB lines) providing
very reliable and flexible motor starter units� The RW_E counts
on two independent and highly reliable built in auxiliary contacts
that assure the motor is switched off when a failure occurs�
Standard Features:
trip class: 10, 20 and 30

Solid-State Overload Relays
Suitable for Great Variety of Applications
The solid-state overload relays RW_E are suitable to protect motors in a wide range of industrial applications including
those where long starting time is required� This way, motors on low, medium or heavy duty applications can be properly
protected just by selecting the proper trip class (10, 20 or 30 according to IEC 60947-4-1) in the DIP-switches�
Additionally, the microprocessed electronic circuits of RW_E are temperature compensated according to IEC 60947-4-1,
which means that throughout the temperature range of -20 °C up to +60 °C, the tripping point is not affected and it
performs consistently without undesirable tripping�
The RW_E also features thermal memory which assures that the heating and cooling effects of motors are modeled and
proper protection is guaranteed even after downtime periods�
