The CJX1 (3TB, 3TF) series AC contactor is mainly used in circuits with AC 50HZ or 60HZ, rated insulation voltage of 690V, and rated current up to 800A under the AC-3 usage category; For remote control of circuits or other electrical appliances, the motor can be frequently started. And it can be combined with appropriate thermal overload relays to form an electromagnetic starter to protect the possible operation overload circuit.
This product complies with GB14048.4, IEC60947-4-1, and GB21518-2008 “Limiting Values and Energy Efficiency Grades for AC Contactors”
