描述

The 84871030 is an EIH type current control relay designed to monitor AC current by passing a cable through its integrated transformer. It features an AC current threshold that is adjustable from 1 to 20 A AC over a frequency of 30 Hz to 400 Hz. This device supports a wide multivoltage power supply, including 24 VDC, 24 VAC, 48 VAC, 120 VAC, and 220 VAC. The unit includes a single changeover relay output rated for a maximum of 8 A at 250 V AC/DC. With adjustable delays for power-up and threshold crossing, it is well-suited for over-current and under-current protection applications, preventing nuisance tripping from transients or motor start-up surges.
