Alltec’s AD3 is a heavy duty AC Surge Protection Device (SPD) tested to UL 1449 4th Edition. The SPD offers convenient DIN rail mounted base with replaceable suppression protection modules. Designed to meet IEC 61643-11 Class II requirements to protect at lightning protection zone 0b-1 boundary.
The SPD employs 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. It employs a “thermal-reactive operational status supervisor” to monitor its operation and provide a means for it to safely disconnect from its power source should it be subjected to a temporary overvoltage (TOV) event.
The AD3 M50 product is intended for use on TNC grounded electrical distributions.
