May be integrated into a motor control system using other Sirius control gear products, e.g. 3 pole circuit breakers from the 3RV10 range (see Control Gear section)
Two phase control, plus soft starting and stopping of three phase asynchronous motors
Low power loss
Adjustable start-up voltage between 40 to 100% of working voltage
Integrated bypass contacts
DIN rail mounting
Compact design and dimensions
Status indication
Solid-state motor overload and intrinsic device protection
Adjustable current limiting
Optional thermistor motor protection (up to size S3)
Integrated remote reset (up to size S3)
Integrated 'self-hold' and 'end of start-up' auxiliary contacts. The self-hold contact is used for interlocking when controlled by a means of a simple 'on-off' pushbutton set up. The 'end of start up' signal may be used to operate other pieces of plant, such as a pump
