Explosion proof actuators -250/315 and -400 P
 
 
 
 
 

Description

The control panel is of blocked type on the basis of the universal reliable control units, fuse, diagnostic and information blocks. Information about status of components of the starter, actuation of protections and value of the load currents is displayed on two monitoring boards made on the highlight LEDs and installed on the front door in the windows of the increased diameter. Circuit of the starter foresees diagnostics of the elements of the control circuits without power supply to the network.

The starters are made in the reversible execution.
