High-Capacity, High-Voltage Power Relay G7J
- On Sale Till 31/03/2025
A multi-pin power relay that achieves high capacity and high voltage and is one step closer to the contactor area.
[Features]
·Its high capacity allows it to be used for not just resistors and inductive loads but also for motor controls.
·No contact chatter occurs even in the event of an momentary voltage drop up to 50% of the rated voltage.
·Achieves withstanding voltage of 4 KV or more between contacts of different polarities as well as between coil and contacts.
·All insulation materials are flame-retardant materials that have passed UL94 V-0 standard.
·Standard product certified by UL and CSA standard.
·Contact gap 3 mm or more (both sides).
[Applications]
·For switch control of compressors and heaters for package air conditioners.
·For switch control of electric tools and various motors.
·For ramp control motor drive and power supply switch control of office equipment such as copiers and fax machines.
· For power controls on packaging equipment and food processing machines.
·For inverter power supply control.
