£323.19
The Carlo Gavazzi RSBT4032EV51HP is a compact and reliable three-phase compressor soft starter designed to provide smooth motor starting, reduced inrush current and improved equipment protection in industrial automation, HVAC and refrigeration applications. As part of the advanced Carlo Gavazzi RSBT soft starter series, it is specifically developed for three-phase scroll compressors and demanding motor-starting applications requiring controlled acceleration and reduced electrical stress.
This high-performance soft starter uses Carlo Gavazzi’s auto-adaptive control technology to optimise starting performance without requiring user adjustments. The integrated bypass relay reduces heat dissipation during normal operation, while the compact DIN rail mounting design enables straightforward installation inside industrial control panels.
With a rated operating current of 32 A AC, an operating voltage range of 340–440 V AC and a 93.5–440 V AC control supply, the RSBT4032EV51HP is suitable for three-phase motors up to 15 kW at 400 V AC, including high-pressure start and multi-compressor applications.
Soft starters such as the Carlo Gavazzi RSBT4032EV51HP gradually control motor starting conditions to reduce electrical current peaks and mechanical stress. This improves system reliability, protects connected equipment and helps extend the service life of motors and compressors.
The RSBT high-performance series is designed for OEM machine builders, HVAC engineers and industrial automation specialists requiring dependable compressor starting solutions. Its integrated bypass, compact DIN rail format and adaptive control algorithm allow simple integration into modern control systems.
