The ACSPR Series features Advanced Surge Protection to protect against power surges/spikes up to 72,000A. This model also includes the Voltage Tolerance Envelope monitor for over/under voltage protection. It has a rocker switch and nine NEMA 5-15R receptacles—a combination of switched (controlled by switch) and un-switched (always on). The panel can be activated/deactivated by an external remote switch, trigger voltage, alarm system, or sequencer connected to rear terminal blocks.
