AC Relays
The E-MAX ATR and ACV Relays are the AC equivalents of the industry standard E-MAX TIR Trip Indication Relays and AVR Auxiliary Voltage Relays. While the TIR and AVR Relays are designed for use in DC trip circuits, the ATR and ACV are designed for use in AC trip circuits. The relay outputs may be used to record breaker, relay, communication and control system operations, and to activate alarm and/or annunciator contacts. Relays do not require standby power to operate; they are powered by their inputs.
