Compact Electromagnetic Contactors That Switch 40 A at 440 VAC

One pole carries 40 A.
UL 508 and UL 840 NC contacts (resistive 40 A 480 VAC, 60 Hz, 80,000 operations).
EN 60947-4-1 NC contacts (AC1 40 A 440 VAC, 50/60 Hz, 80,000 operations).

Ideal for supply power to industrial inverters, servo drivers, and other devices, and switching power to motors and other equipment.

The maximum load capacity of 160 A when using 4-pole parallel connections.

EN 60947-4-1 certification for mirror contact mechanism obtained by combining the Relay with an Auxiliary Contact Block.

Conforms to European PV standard (VDE0126).

Approx. 30% less operation noise than a standard electromagnetic contactor.*
(Approx. 100 dB reduced to approx. 70 dB.)

Approx. 50% the volume of a standard electromagnetic contactor* to help downsize control panels.

* According to OMRON investigation of IIEC-AC1 50 A specifications.

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.

G7Z Features 9

Compact Size

Downsizing of approximately 40% volume compared with contactors.*
Contributes to space savings in control panels.
* IEC-AC1 50-A specifications

DIN Track Mountable

G7Z Features 11

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
