Crouzet Monitor - Relay Output LIART24A

The LIAR.T series is a current control relay designed to monitor AC currents from 5 to 100 A RMS, with automatic or manual unlatching and adjustable hysteresis from 5% to 50%. It operates on 24 VAC input power and uses a plug-in 11-pin mounting style. The unit includes a start-up inhibit function with a selectable delay of 0.1 to 10 seconds, and an output relay rated for 10 A AC resistive or 1 A DC inductive loads at 250 VAC maximum switching voltage. The relay has a mechanical life of 30 × 10⁴ operations and an electrical life of 2 × 10⁵ operations at 2500 VA resistive load. Operating temperature ranges from -10°C to +60°C, and the device meets UL and CSA standards. Weight is 200 g. A separate current transformer (Part Number 74 525 305) is required for current sensing.
