SW64 - 2 x SW60 on Double Bracket (Part of the SW60 Series) Thermal Current Rating (Ith) Intermittent Current Rating: 30% Duty 400A at 96V D.C. Rated Fault Current Breaking Capacity (Icn) Resistive Load: (in accordance with UL508*) 120A at 60V D.C. Maximum Recommended Contact Voltages (Ue): SW64 Uninterrupted current - no or infrequent load requirements (maintains a lower contact resistance). Typical Voltage Drop per pole across New Contacts at 80A Dimensions in mm [inches] Enclosed top cover standard when blowouts not fitted Mechanical M.T.B.F The SW64 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW64 has M6 stud main terminals and 6.3mm spade coil connections and can be mounted via M4 tapped holes or mounting brackets, either supplied fitted, or as separate items. Mounting can be on the side or base of the contactor. Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance). Rated Fault Current Breaking Capacity (Icn) 5ms Time Constant: (in accordance with UL583*) SW64 The SW64 is a miniature series single pole, free standing, compact contactor. It is designed to fill the gap between 30 ampere relays and 100 ampere contactors. Devised for both interrupted and uninterrupted loads, the SW64 is suitable for switching Resistive, Capacitive and Inductive loads. Typical applications include switching small traction motors, hydraulic power packs and small electric winch motors. Coil Voltage Available (Us) (Rectifier board required for A.C.)
