New Product Power Relays G7Z Compact Electromagnetic Contactors That Switch 40 A at 440 VAC One pole carries 40 A. UL 508 and UL 840 NO contacts (resistive 40 A 480 VAC, 60 Hz, 80,000 operations). EN 60947-4-1 NO 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 For the most recent information on models that have been certified for safety standards, refer to your OMRON website. 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. Be sure to read the Safety Precautions on page 8 and the Precautions for All Relays with Forcibly Guided Contacts.
