The SW822 series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks, powered invalid cars, etc.
They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.
This contactor has fast drop out times and relatively slow pull-in times. Therefore motor direction changes can be undertaken without risk of all contacts being closed at the same time.
However, certain types of coil suppression such as diodes substantially increase drop out times and care must be taken to ensure suitable suppression is fitted e.g. diode and resistor in series.
They are economical in price and compare favourably with sealed automotive style solenoid switches which cannot be serviced or inspected for contact wear.
Compact Size: The contactors are compact in size and are fully serviceable with a full range of spare parts available.
Installation: Mounting is via the supplied mounting bracket.
Operating Coils: Available with 6-240v DC coils, coil connections are by means of 6mm spades of which two are supplied per terminal.
