Product Description

​The Omron K2CU-F20A-D is a Heater Element Burnout Detector designed to monitor and protect heating elements in industrial applications. It accurately detects burned-out heater elements, even when multiple elements are used, by measuring the operating current and providing alarm signals when anomalies are detected. This model is suitable for heaters with operating currents ranging from 8 to 20 A and operates with a control supply voltage of 110 VAC at 50/60 Hz.
