DESCRIPTION

The LNRU110A is a liquid level control relay designed for monitoring and controlling conductive liquids such as tap water, seawater, sewage, and chemical solutions. It features a 10 Amp SPDT relay with AgCdO contact material, LED indicator, and pump-up control functionality with adjustable probe sensitivity ranging from 4.7 kO to 100 kO. The device operates at 110 VAC (±15%, 50/60 Hz) with a maximum power rating of 2500 VA and supports both dual-level and single-level control modes. With an electrical life of 2×105 cycles at 2200 VA resistive load and mechanical life of 3×106 operations, the LNRU110A is ideal for industrial applications requiring reliable liquid level monitoring and pump control in tanks and reservoirs.
