Since the products from the innovative SIRIUS modular system are matched to one another
both electrically and mechanically, they can be combined quickly and easily.
The 3RA28 function modules are designed for size S00, S0, S2 and S3 contactors. The
operating range of the 3RA28 function modules is 0.85 to 1.1 Us. You can mount the
function modules on the front of SIRIUS 3RT2/3RH2 contactors or 3RA24 contactor
assemblies.
3RA24 pre-wired assemblies are available for star-delta (wye-delta) start.
