Power Relays 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 fo r 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.

Rated current and coil resistance were measured at a coil temperature of 23C with coil resistance of 15%. 2. Operating characteristics were measured at a coil temperature of 23C. 3. The maximum allowable voltage is the maximum value of the fluctuation range for the Relay coil operating power supply and was mea- sured at an ambient temperature of 23C. There is, however, no continuous allowance.
