Surge Protection Device 320VAC – Citel, high voltage protection

Surge protection device 320VAC are mainly used for the primary protection of single 4- phase networks at the main electrical panel. They provide common-mode or common and differential mode. This lightning surge protector is based on high voltage protection equipped with a thermal disconnector and failure indicator, to comply with standards. The Surge protection device 320VAC is designed to be used in a multipolar configuration to protect single-phase, 3-phase, or 3-phase+Neutral AC networks. They are sometimes associated with a dedicated N/PE surge protection based on gas tube technology.
