Product Description

Details

The Albright SU280 series contactor is perfectly suited for winch isloation or heavy duty battery split charge systems.They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.

Mounting is by means of 5mm tapped holes in the switch frame together with a range of mounting brackets complete with screws and washers.
 
12V DC coil, coil connections are by means of 6mm spades of which two are supplied per terminal.
