Soft start drive
VersiStart II
[17 - 45A]

Features

• two-phase controlled soft starter
• controlled by microcontroller
• optimized soft start

• easy mounting, for snap-mounting on 35 mm standard rail
• integrated bypass relay
• parameterization by means of three potentiometers
• no additional control voltage required
• no mains neutral conductor (N) required
• economically priced substitute for star-delta starters
• plug-in power terminals
• control outputs with spring-loaded terminals
• heat sink temperature monitoring
• compact design, 45mm up to 32A and 52,5mm at 45A
• degree of protection IP20
