DESCRIPTION FEATURES
Lightning and power line surges can seriously damage or disrupt operations in hospitals, reservation systems, banks, stock exchanges and other mission-critical activities.

The SF400M, through its extraordinary surge current diversion capability, protects your sensitive system from damaging transients, thus eliminating "downtime" and its associated financial and lost labor costs.

The SF400M diverts surge currents to ground  by way of  6 heavy-duty pathways. The unit's low impedance design assures a minimum let-through voltage to sensitive downstream equipment. The plug-in, pluck-out protection modules guarantee an easy 5 minute repair.

The SF400M is equipped with an advanced  diagnostic system. The front panel LCD shows  percentage of protection, number of transient events and a date/time stamp. In addition, a remote fault indicator and audible alarm are provided.
