Thermal Current Rating (Ith) Intermittent Current Rating: 800A at 80V Rated Fault Current Breaking Capacity (Icn) Resistive Load: (in accordance with UL508*) 190A at 60V D.C. 190A at 96V D.C. Maximum Recommended Contact Voltages (Ue): SW80 Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). The SW80 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW80 has M8 stud main terminals and 6.3mm spade coil connections. Mounting is via M4 tapped holes or mounting brackets, either supplied fitted, or as separate items. 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. Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance). The SW80 has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks, and telecom and power distribution applications. Developed for both interrupted and uninterrupted loads, the SW80 is suitable for switching Resistive, Capacitive and Inductive loads. • 150A Rated Fault Current Breaking Capacity (Icn) 5ms Time Constant: (in accordance with UL583*) SW80 SW80 Single Pole Single Throw Normally Open (Part of the SW80 Series) Typical Voltage Drop per pole across New Contacts at 100A Mechanical M.T.B.F Coil Voltage Available (Us) (Rectifier board required for A.C.)
