Australia Post Express Satchel - $28.60


These are a low-cost alternative to the Albright range of contactors, and are of a very similar design.

This particular assembly is basically two ZJWH400A contactors back to back, plus copper interconnects to configure it for reversing the polarity of an electric motor (or just the rotor in a series DC motor). It should be wired up so one energising one coil activates forward drive, and the other coil activates reverse. Energising neither or both coils results in an open circuit, as a failsafe.

Contacts are rated to 400 amps continuous, but can handle up to 1000A instantaneous. There is a 12 volt solenoid to close the contacts which draws about 1.2 amps when energised.

Terminals are 3/8\" diameter, cable lugs with 10mm hole are a good fit.
