The new, higher amperage, RSBT and RSBD Series of 3 and 2- phase controlled scroll compressor soft starters are the extension of the existing RSBT Series to cover most existing scroll compressor ratings available in the market. Equipped with the patented auto-adaptive algorithm, an optimized inrush current reduction with every start, achieved without any user setting is a simpler product to deploy and operate. Without a need for any external sensors, soft starters offer a number of built-in diagnostic functions to protect the user's system against potentially harmful conditions such as wrong phase sequence and locked rotor condition.

Common applications for scroll compressor soft starters in HVAC market are in chillers, heat pumps and roof tops. Benefits of using RSBT and RSBD Series soft starters include current limiting starting, auto-adaptive starting algorithm, no user settings required, reduction of system vibration and longer compressor lifetime.

Technical specifications include:
	Current ratings up to 55, 70 and 95A
	Maximum UL rating of 75Hp
	Line voltage rating up to 480VAC
	Universal control 24VAC/DC & 110-400VAC
	Up to 12 starts per hour
	CE certified, UL and cUL listed
