HSW600 1R J - 

600W Water cooled aluminum housed wirewound power resistor, HSW600 Series
The HSW600 series are suitable for use where water cooling is available and space is limited. Heat is extracted internally through the cooling pipe and externally by direct mounting onto a chassis or additional water cooled heatsink, thereby reducing temperature gradient across internal insulation. Applications include semiconductor protection and inrush current limiting. The HSW600 series has a standard beaded copper 12.7mm OD waterpipe connection and PTFE insulated flexible leads. (19/0.45mm)
