G7Z

Multi-pole Power Relay for Carrying and Switching

Contactor Current Range of 40 A at 440 VAC

• 40 A can be carried and switched on each of 4 poles.

• Possible to reach a maximum load capacity of 160 A when

using 4-pole parallel connections.

• EN 60947-4-1 certification for mirror contact mechanisms

has been obtained by using a combination of the relay and

auxiliary contact blocks.

• Typical applications: high current or high inrush power

supplies, commercial and industrial.

• RoHS compliant.
