Carlo Gavazzi RSBT2225EV11 three-phase compressor soft starter with 25 A rated current designed for scroll compressor motor starting control in HVAC and industrial applications.
£331.78
The Carlo Gavazzi RSBT2225EV11 is a compact three-phase soft starter for scroll compressors designed to reduce starting current and provide smooth acceleration of compressor motors in HVAC, heat pump and industrial cooling applications. As part of the advanced Carlo Gavazzi RSBT compressor soft starter series, it uses an auto-adaptive current limiting algorithm to optimise compressor starting performance without requiring manual adjustment.
This soft starter provides reliable motor starting control while helping reduce mechanical stress, electrical inrush current and compressor wear. The RSBT series features integrated bypass technology, LED indication and compact construction, making it suitable for demanding compressor control installations.
With a rated current of 25 A and a 220 V AC three-phase operational voltage, the RSBT2225EV11 is designed for three-phase scroll compressor applications. Its compact housing with DIN rail or screw mounting options enables straightforward installation inside electrical control panels.
Soft starters such as the Carlo Gavazzi RSBT2225EV11 control the initial current supplied to compressor motors during startup. By limiting starting current and providing controlled acceleration, they help improve system reliability while reducing stress on electrical and mechanical components.
The RSBT series is specifically developed for three-phase scroll compressor applications. Its integrated bypass relay, adaptive starting technology and compact construction allow reliable integration into HVAC systems, heat pumps and industrial control panels.
