Siemens 3RW4076-6BB44 Soft Starter 3RW40 SIRIUS Soft Starter
• Sirius 3RW40
• 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
• The 'end of start up' signal may be used to operate other pieces of plant, such as a pump
• Ideal replacement for DOL and Star-Delta starters
