Mitsubishi - MS-N Contactors

Substantial safety and functionality realized with a full lineup

Incorporation of CAN terminal for simple wiring
By adopting a CAN terminal, there is no need to remove the screws, and losing of the terminal screw is prevented by the integrated screw holder and terminal screw. The terminal screw is set in a plastic screw holder. When each pole is moved and the screw loosened, the screw is naturally set in the screw holder. This is Mitsubishi's original CAN terminal (Patented)

Unified design for N-Series
The design has been unified for the MS-N series. The front face of the product is a bright white color, making the inside of the panel brighter and providing a clean image

Arc space reduced to approximately one-third
By adopting the new extinguishing mechanism, the arc space has been reduced to approximately 1/3 (Mitsubishi comparison)

Compatible with International standards
Applicable standards : JIS, JEM, IEC, EN, VDE, BS
Approved standards : UL, CSA, LR, BV, NK, KR, TUV, GB
