Description
GLVAC GL250HTANA, 250A, 800Vdc DC Contactor / Power Relay
GLVAC offers the GL250HTANA High Voltage DC Contactor or power relay for switching 250A continuous current. Main contact is SPST-NO with SPST-NO aux. contact.
-Ceramic-Metal seal—uses highly reliable ceramic sealing technology and is filled with strong arc
cooling ability of gas,which can rapidly cut off the DC load
-Ceramic seal—to prevent the exposure of arc,contact in a sealed environment ,contact resistanceislow
and stable,can work in harsh environment. The intermal protection level of contact can reach IP67.
