DC64P Monoblock, 2 x SW60 (Part of the SW60 Series) The DC64P has been designed for direct current loads, such as motors used on small winches. The DC64P is a monoblock construction, resulting in a compact design which is compatible with modern electronic control systems. Devised for both interrupted and uninterrupted loads, the DC64P is suitable for switching Resistive, Capacitive and Inductive loads. • Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance). Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). Thermal Current Rating (Ith) Intermittent Current Rating: 30% Duty The DC64P has double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The ‘P type configuration offers greater environmentally protected switches, compliant to IP66. The DC64P has M6 main stud terminals and coil connections are by means of 6.3mm spades.
