This SM161-4VAI model is supplied with internal overload motor protection to prevent excessive current draw, overheating & phase loss or incorrect motor rotation. The cutout current is the MCC value & can be found in data sheets. The protector is located in the star point of the motor & will cut out all three phases when activated & will automatically reset. Although not compulsory it is advisable to fit additional external overload protection for alarm or manual reset.
The SM range of compressors benefit from the improved design features below to achieve the highest efficiency:
• Gas circulation, motor cooling and oil behaviour are improved on light commercial platform models by a new patented motor cap design.
• Part protection and assembly reduces internal leaks and increases life durability.
• Improved part isolation reduces greatly acoustic levels
• Gas intake design induces higher resistance to liquid slugging.
• R22 optimized and charged with mineral oil
Note: Crankcase heater is not supplied with compressor & should be purchased separately if required.
