Product Overview

The CAH20A2BD is a 1-pole AC over- and under-current Sensing Relay with ON power-UP function, SPDT contact configuration, 0.15 to 7 seconds delay. IT can detect either an over-current or undercurrent fault. After input voltage is applied and the sensing delay on power-up (tS) is completed, the unit will begin sensing for a fault condition. A fault will occur when the monitored AC current (I) goes above the Fault Trip Current setting and remains above the Reset level for a period longer than the adjustable time delay period (t). The LED will turn ON immediately and the relay will energize after the time delay on pick-up (t) is completed. The relay will de-energize and the LED will turn OFF when the monitored AC current goes below the Reset level. Encapsulated for protection in harsh environments.
