Product Description
DC COTNACTOR SW822
SW822 DC COTNTACTOR
the contactors has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks, airport tractors, and such like.
They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.
Compact Size: The contactors are compact in size and are fully serviceable .
with a full range of spare parts available.
Installation: Mounting is by means of 5mm tapped holes in the switch frame together with a range of mounting brackets complete with screws and washers.
Operating Coils: Available with 6-240v DC coils, coil connections are by means of 6mm spades of which two are supplied per terminal.
Magnetic Blowouts: Fitting of magnetic blowouts make the polarity sensitive and the positive markings on the top cover of the contactor must be observed. Suffix 'B' denotes the fitting of magnetic blowouts.
Auxiliary Contact: Denoted by 'A', a double circuit normally open, normally closed microswitch auxiliary contact can be fitted, ratings as shown below
