Product Description
38A Reversing Contactor
Model: CJX1-38N
Reversing Contactors (Magnetic Contactor) provide remote control of primarily electric motors and compensation & heating systems by cable. They protect the instruments and equipments against overload currents by using thermal relays, for capacitor switching contactor. While switching on a capacitive circuit, a high frequency (1...15Hz) and large transient current peaks are produced. Switching of capacitor for a single or one of the capacitor banks are different from each other. Step by step "switching on" operation is more difficult for contactor than capacitor bank. Because during this operation for capacitor bank, compensated current occurs. For this reason selecting of suitable contactors the compensating current must be take into consideration for 50kVAR and above, and for less than 50kVAR can be omitted.
- 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.
