The mSA range of surge protection devices is designed to safeguard remote electronic equipment from surges on signal and data cabling. Models are available in a range of working voltages to cover all process-related signals such as RTDs, THCs, 4/20mA loops, telemetry outstations, shut-down systems and fire and gas detection. The weatherproof enclosure of the mSA range is rated at IP65 making it particularly suitable for locations which are regularly exposed to lightning activity and suffer frequent damage.
