• The maximum load capacity of 160 A when using 4-pole parallel connections.
• All materials used are compliant with the RoHS Directive
• EN 60947-4-1 certification for mirror contact mechanisms has been obtained by
using a combination of the relay and auxiliary contact blocks.
• A design with a small number of openings makes it difficult for dust or foreign
matter to enter.
• Ideal for supply power to industrial inverters, servo drivers, and other devices,
and switching power to motors and other equipment.
• Conforms to European PV standard (VDE0126).
Be sure to read the “Safety Precautions” on page 6 and the
“Precautions for All Relays with Forcibly Guided Contacts”.

Safety Precautions
Refer to the “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided Contacts”.
• The Relay can be mounted directly on a mounting rail (PFP) or a
DIN Track (EN 50022-35 × 7.5, 15). The Relay cannot be mounted,
however, to some reinforced rails (e.g., those produced by
!WARNING
Take measures to prevent contact with charged parts
when using the Relay for high voltages.
Kameda Denki or Toyogiken).
• Mount the Relay sideways when it is mounted on a rail.
• Use End Plates (PFP-M) on both sides of the Relay to make sure
that it is properly secured.
!CAUTION
Up
Do not touch the terminal section (charged parts) when
power is being supplied.
Always use the Relay with terminal covers mounted.
Contact with charged parts may result in electric shock.
Do not touch the Relay when power is being supplied or
right after the power has been turned OFF.
The hot surface may cause burn injury.
DIN Track

• Provide at least 5 mm of space between the sides and top of the
Relay and nearby grounded metal surfaces.

dimensions.

connect a bleeder resistor if necessary.

• The must operate voltage is the minimum value for the Relay
armature to operate and the contacts to turn ON. Therefore,
fundamentally apply the rated voltage to the coils, taking into
consideration the increases in coil resistance caused by voltage
fluctuation and coil temperature rise.

• Counter-electromotive voltage generated by the coil when the coil
is OFF may destroy semiconductor elements or cause
malfunctions. Attach surge-absorbing diodes to both ends of the
coil as a countermeasure. Particularly, when driving G7Z with
semiconductor elements, always attach the surge-absorbing
diodes.

Relay Coil

4.3
Note that the relay reset time will be extended, so always use after
verifying implementation under actual usage conditions.
Use surge-absorbing diodes with a minimum of 600 V reverse
voltage resistance, and a forward current of approximately 1A.
G7Z does not have coil polarity so attach surge-absorbing diodes
so that the polarity is reverse to the applied voltage of the coil.

By combining a Relay with an auxiliary contact block, all NC contacts

of 2.5 kV or higher or maintain a gap of 0.5 mm or greater when the
coil is de-energized even if at least one NO contact (main contact) of
the Relay is welded.
