Marine Limit Switch
Overview
LX918 series limit switches are suitable for AC 50~60Hz voltage up to 500V and DC voltage up to 440V circuits, used to control the travel of various mechanisms, and can directly start and stop 5.5kW three-phase asynchronous motors (mainly used for the secondary circuit of the motor).
Structure and Working Principle
The shell of the limit switch is made of zinc alloy, which has good mechanical strength and good corrosion resistance. Under the marine cabin environment conditions, the performance of the material will not degrade. The shell type is waterproof type, with a protection level of IP67. Due to the spring action, it can automatically reset. Operating position: 45°C ~ 45°. The contact disconnection of the limit switch is determined by the opening and closing positions of the cam.
Standards and Certificates
Complies with the special requirements of IEC337-2 control switches, and has passed the inspection of the China Classification Society, and has obtained the approval of the classification society. The nameplate is marked with the CCS wheel mark.
