Overload relays
Protection concepts for your individual needs

Thermal and electronic overload relays Easy application and storage
Cut your costs
provide, in combination with contactors, Overload relays are a perfect fit to ABB’s
reliable protection against overloads and contactors (e.g. AF, mini contactors) and can be
directly mounted and connected without further
phase failures for motors. They allow to wiring. By combining wide current setting ranges
set up customized motor starting with three trip classes, electronic overload relays
allow to reduce the number of variants in stock.
solutions according to individual needs
Continuous operation
Secure uptime
The selectable automatic reset mode allows
to reduce downtimes and travelling costs for
installation in dispersed locations. The manual
reset mode can be complemented by the DRS-F
reset coil that allows a remote control over large
distances.
Optimized design
Efficient operation
Electronic overload relays combine a high accuracy
with an energy efficient design that does not need
extra external supply. Thanks to its overlapping
current setting ranges, the usage at the limits of
the setting range can be avoided which reduces
power heat loss.
