RSBT2216EV10 – 3 phase compressor softstarter 220V 16A, 110-400V I/P

Why Choose the Carlo Gavazzi RSBT2216EV10 Compressor Soft Starter?

The Carlo Gavazzi RSBT2216EV10 is a compact and intelligent three-phase scroll compressor soft starter designed to reduce starting current in HVAC, refrigeration and heat pump applications. As part of the Carlo Gavazzi RSBT compressor soft starter series, it uses a patented auto-adaptive starting algorithm to optimise compressor starting performance without requiring manual adjustment of starting parameters.

The RSBT2216EV10 controls all three phases and incorporates an internal bypass, providing an efficient and compact solution for compressor starting. Its current-limiting, auto-adaptive starting method analyses compressor behaviour and automatically optimises each start, helping reduce inrush current, supply disturbances, light flicker and mechanical vibration in connected pipework and joints.

With a rated operational current of 16 A AC and a nominal operational voltage of 220 V AC, the RSBT2216EV10 is designed for three-phase scroll compressor systems. The EV control input accepts 110–400 V AC, with an operating control voltage range of approximately 93.5–440 V AC, providing broad compatibility with industrial HVAC and refrigeration control circuits.

Intelligent Starting for Three-Phase Scroll Compressors

Direct-on-line compressor starting can produce high inrush currents that place additional demand on the electrical supply and can contribute to voltage disturbances and mechanical vibration. The Carlo Gavazzi RSBT2216EV10 uses current limiting and an auto-adaptive algorithm to control the starting process and automatically optimise performance for the connected compressor.

The RSBT series is specifically engineered for scroll compressor applications rather than general-purpose motor starting. Once the compressor reaches normal operation, the integrated bypass provides an efficient current path while the soft starter continues to provide monitoring and diagnostic functionality. The compact format makes the RSBT2216EV10 particularly suitable for integration into HVAC, refrigeration and heat pump control equipment.
