SW92 - 2 x SW80 on Double Bracket (Part of the SW80 Series) The SW92 has been designed for direct current loads. Developed for both interrupted and uninterrupted loads, the SW92 is suitable for switching Resistive, Capacitive and Inductive loads. Thermal Current Rating (Ith) Intermittent Current Rating: Rated Fault Current Breaking Capacity (Icn) 5ms Time Constant: (in accordance with UL583*) SW92 Maximum Recommended Contact Voltages (Ue): SW92 Typical Voltage Drop per pole across New Contacts at 100A: Normally Open Mechanical M.T.B.F 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). The SW92 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW92 has M8 stud main terminals and 6.3mm spade coil connections. Mounted using supplied brackets, 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. Coil Voltage Available (Us) (Rectifier board required for A.C.)
