SU60 Single Pole Single Throw Normally Open (Part of the SU Series) Application Thermal Current Rating (Ith) The SU60 is a high rated freestanding compact contactor devised for both interrupted and uninterrupted loads, and is suitable for switching Resistive, Capacitive and Inductive loads. Typical applications include motors as used on small electric vehicles and hydraulic power packs. Intermittent Current Rating: 30% Duty Rated Fault Current Breaking Capacity (Icn) 5ms Time Constant: (in accordance with UL583*) SU60 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 SU60 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SU60 has M8 stud main terminals and 6.3mm spade coil connections. It 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. 500A at 96V D.C.
