AC CONTACTOR LS

APPLICATION

LS AC Contactor mainly applies to of AC 50/60Hz, rated working voltage up to 690V, current to 630A for long distance frequently making and breaking the circuit of motoe. LS can be used with 3SR9 thermal overload relay to form magnetic starter to protect the motor from overload and phase failure.

LS feature double breaking contacts. LS-4 TO LS-17 is 4 pole,LS-27 to LS-637 is 3 pole contactor.

The product complies with standard of IEC60947-4.
