75A 3POLE Contactor

75A 3POLE Contactor

Model: CJX5-75

• Magnetic Contactor should have the high current value without being exposed to and damaged or boiling. This belongs to the quality of contactor. (Contact surface quality and weld technology) Especially at AC-3 and capacitor command, selectivity of contactor is very important.
•  
• Current which passes through the contacts causes warming when the contactor is closed. This warming is limited with the standards. For IEC60947-4-1 when continual thermal current (Ith) is passed though the main contacts, maximum increasing temperature should not exceed 65k.
•  
• While the contactor is cutting the current, electrical arc occurs between the seperated contacts. Arc is the result of the thermal impression of electron and ion current which broke off the contact material. Temperature of the arc reaches to thousands of degrees and this temperature is too high for metals and insulators which are used at contact making and cutting cells. Therefore, arc should end as soon as possible. For this reason separators are used inside of contactors.
