CSM_G7Z_DS_E_6_1

Multi-pole Power Relay for Contactor Current Range
Capable of Carrying and Switching 40 A at 440 VAC
• One pole, 40 A can be carried and switched.
• 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”.
