25 AMP Core Drill Switchbox


The SB-400-25 is a rugged, cast aluminum switchbox that is used with the matching 200V, three phase, 400HZ electric motors that power our range of core drills, slab saws, and other concrete cutting equipment.

The ampmeter is a sealed, high reliability type that reads in percentage of loads with a red zone to indicate motor overload.

The Switchbox has one 73 Amp inlet plug and one 73 Amp output plug for simplicity.

Additional outlet plugs, available with or without controlling switches can be added to the switchbox for convenience.
