High-capacity Power Relays
for Use in Contactor Current Ranges
Customers want to use contactors with greater ease for
AC 1 class (IEC load) switching, and the G7Z Power
Relays were developed to meet those needs. As the
No.1 leader in production performance in Relays,
OMRON has implemented crossover technologies for the
new design of the G7Z.
Along with providing switching in the conventional
contactor range of 40 A with the size
and convenience of a conventional relay,
we have also achieved an ecological
relay-the user-friendly, high-capacity G7Z.

Downsizing of approximately 40% volume compared with contactors.*
Contributes to space savings in control panels.
* IEC-AC1 50-A specifications
The Relay can be easily mounted right on a DIN Track.
Application Example: General Safety Circuit
G9SA-301 (24-V AC/DC) (two limit switch input channels with manual reset)
Compact Size

DIN Track Mountable
Feedback circuit
Continuously apply 40 A at 440 VAC,
or apply up to a maximum of 160 A
by using 4-pole parallel connections
for full power application.*
The Relays are highly insulated to
support load switching
of 40 A at 440 VAC
EN 60947-4-1 certification for mirror contact mechanisms has been obtained by
using a combination of a relay and auxiliary contact blocks (5 VDC, 1 mA),
enabling application in feedback circuits of safety circuits.
* IEC-AC1 50-A specifications
Low noise of approx. 70 dB compared with the approx.
100 dB for contactors.* Low power consumption of less
than 4 W DC. Environmentally friendly specifications.
* Always consult with your OMRON representative
before using the maximum current of 160 A.
