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.

High Capacity and
High Insulation
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.
*Always consult with your OMRON
representative before using the maximum current of 160 A.
Compact Size
By downsizing of approximately 40% volume
compared with contactors*, G7Z Power Relay contributes to space savings in control panels.
* IEC-AC1 50-A specifications
Safety Function
with Mirror Contacts
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.
Low Noise and Low
Power Consumption
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.
* IEC-AC1 50-A specifications
DIN Track Mountable
The Power Relay can be easily mounted right on
a DIN Track.
