SW68P Double Pole Single Throw Normally Open - IP660 pages
SW68P Double Pole Single Throw Normally Open - IP66
(Part of the SW60 Series)
80A
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.
•t
Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance).
•t
Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).

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.
