£457.10
The Carlo Gavazzi RSBT4025EVC1HP is a compact three-phase high-pressure soft starter for scroll compressors designed to reduce starting current and provide smooth acceleration of compressor motors in HVAC, heat pump and refrigeration applications. As part of the advanced Carlo Gavazzi RSBT HP soft starter series, it combines high-pressure compressor starting optimisation with RS485 Modbus communication for integration into modern automation and monitoring systems.
This soft starter provides reliable compressor motor starting control while helping reduce electrical inrush current, mechanical stress and vibration during startup. The RSBT4025EVC1HP features integrated bypass technology, three-phase control, internal supply and compact DIN rail mounting for straightforward installation inside electrical control panels.
With a rated current of 25 A, an operating voltage range of 187–440 V AC and a 110–400 V AC control voltage range, the RSBT4025EVC1HP is suitable for three-phase scroll compressor applications requiring reliable high-pressure starting performance and RS485 Modbus communication.
Soft starters such as the Carlo Gavazzi RSBT4025EVC1HP 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 HP series is specifically developed for demanding scroll compressor applications where high starting pressure conditions may occur. Its auto-adaptive current limiting technology, integrated bypass function and Modbus communication capability allow reliable integration into HVAC systems, refrigeration equipment and industrial automation networks.
