The MA3350 surge supressors are available for either AC or DC applications. The AC & DC versions are rated to a full 50kA (8/20µs) with the DC version also rated at 15kA (10/350µs). In the AC three phase unit there are four (4) such modes giving a total unit rating of 200kA. These MA3350 surge supressors carry a suite of diagnostics that monitors each component of the suppression circuit. Each unit has positive indication showing both the presence of power and the status of the unit. Red and green LEDs leave the user in no doubt of the MA3350's operational readiness.

Remote monitoring of the MA3350 surge supressors is possible using the standard voltage free contacts.
