Description
Alltec’s AD1 is a heavy duty ANSI/UL 1449 4th Edition Recognized AC Surge Protection Device (SPD). The SPD offers convenient
DIN rail mounted base with replaceable suppression protection modules. AD1 products are designed to meet IEC 61643-11 Class II requirements to protect at lightning protection zone 0b-1 boundaries. They employ fast acting high energy dissipating metal oxide varistors (MOV) in their suppression circuits to deliver high capacity equipotential bonding contingencies for lightning induced surge current. They are equipped with a “thermal-reactive operational status supervisor” to monitor their operation and provide a means for them to safely disconnect from their power source should they be subjected to a temporary overvoltage (TOV) event.
The AD1 product is intended for use on TNC grounded electrical distributions. It can also be utilized to protect TNS and TT grounded services when augmented with an AD1-G50 Series gas tube based suppressor module to provide equipotential bonding between the Neutral and Ground (N- PE).
