The product is mainly used in the EPS power supply of the communication base station, and the contacts can also be used for AC loads of 380V, 220V and 110V.
Application
ZJW200-33 DC Contactor 48v 200a consists of the coil, iron core, contacts, and protective components. When a control current is applied to the coil, a magnetic field is formed, causing the iron core to attract the contacts to close or open.
Ordering Notice
For example: ZJW200-33S/12V
The DC contactor of main contact is 3NO+3NC, with micro switch, vertical installation, rated voltage not more than DC80V, current 200A, coil voltage is
