The AC Fail option for Surge Blox™ surge suppression panels rapidly detects and provides alarm notification when site power is lost. The AC Fail option cleanly connects to a DIN rail included in the Surge Blox™ panel. Form C contacts provide remote alarming.

This option is installed at the factory, simplifying on-site panel connection. The AC Fail option will require appropriate circuit breaker or fusing when connected to line sources.
