MS-N Series DC Operation Electromagnetic Contactor Features

SD-N220

Can use for DC operation of operation coil using a separate power supply, etc. (AC and DC can both be used for the main circuit.)
No electromagnet noise occurs.
Direct application of full voltage, dedicated to DC.
Because no conservation resistance is used for the coil, there is no inrush current (excluding N600 type).
The SD-N600 type operation coil terminal is polarized. Connect positive side to terminal number A1 (+), and negative side to A2 (-).
Auxiliary contacts are a combination of twin movable contacts and a grooved contact, further increasing contact reliability.
Standard model that can accommodate a variety of situations.
Ease of use, safety, and international compatibility combine to provide accurate motor control and protection.
