The N86F-E system is intended for setting switches and derailers with the use of electric point machines equipped with three-phase motors working in a six-wire system. It is mounted on a JAZ board. This system is designed to work with single and coupled drives, equipped or not with blade position controllers.
A variation of the N86F-E system has been designed to be controlled from station control command and signalling devices. The N86F-E system has a bursting point control system. Also, the system is equipped with a timer that prevents the engine from running too long in the event of an obstacle preventing the switch from moving to the end position. Built-in timer reduces the drive operating time, thanks to which the motor is protected against overheating..
