DC92 Monoblock, 2 x SW80 (Part of the SW80 Series) The DC92 has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks. Developed for both interrupted and uninterrupted loads, the DC92 is suitable for switching Resistive, Capacitive and Inductive loads. Thermal Current Rating (Ith) Intermittent Current Rating: Maximum Recommended Contact Voltages (Ue): DC92 Typical Voltage Drop per pole across New Contacts at 100A Mechanical M.T.B.F Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). The DC92 features double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The DC92 is a monoblock construction, resulting in a neat compact design which is compatible with modern electronic control systems. The M8 stud main terminals can be configured in a variety of ways in order to suit the application. Supplied with a mounting bracket as standard, or alternatively supplied with M4 tapped holes. Mounting can be horizontal or vertical, when vertical the M8 contact studs should point upwards. If the requirement is for downwards orientation we can adjust the contactor to compensate for this. Rated Fault Current Breaking Capacity (Icn) 5ms Time Constant: (in accordance with UL583*) DC92 Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance).
