DESCRIPTION FEATURES
The SF120M is designed for branch panel applications. Highly automated areas such computer rooms, UPS equipment, mobile broadcasting, medical, and military vans are guarded from damage, errors, and downtime resulting from high speed transients.

The SF120M is a mid-building suppressor with extraordinary surge current diversion capabilities. Protection of sensitive electronic equipment from external or internally generated transients is assured by this heavy duty protector. The plug-in, plug-out protection modules guarantee a quick and easy 5 minute repair in the unlikely event of catastrophic transients.

The SF120M is designed to MICRO-Z specifications which translates to a dramatic reduction in the voltage drop internally as well as on the provided low impedance power cable. On-board diagnostics include front panel and internal LEDs, transient event counter, audible alarm and remote alarm. In addition, the unit is housed in a rugged indoor/outdoor NEMA4 enclosure.
