SW68P Double Pole Single Throw Normally Open - IP66 (Part of the SW60 Series) The SW68P is a miniature series double pole, free standing, compact contactor which is sealed to IP66. The SW68P is designed to fill the gap between 30 ampere relays and 100 ampere contactors. Devised for both interrupted and uninterrupted loads, the SW68P is suitable for switching Resistive, Capacitive and Inductive loads. Typical applications include switching small traction motors, hydraulic power packs and small electric winch motors. • 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). Thermal Current Rating (Ith) Intermittent Current Rating: 30% Duty The SW68P features double pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW68P incorporates an enclosed top cover and offers environmental protection to IP66. The SW68P has M6 stud main terminals and 6.3mm spade coil connections. It can be mounted via mounting brackets (supplied fitted). Mounting can be on the side or base of the contactor.
