The current control relay is designed for overcurrent detection and is compatible with a wide range of industrial automation applications including hoisting, packaging, lifts, and textile processing. With a rated supply voltage spanning from 24 to 240 V AC/DC, it supports a nominal output current of 8 A and features two changeover (C/O) contacts.

This modular relay has a compact width of 22.5 mm, allowing it to be easily installed on a DIN rail, occupying the same space as a standard 1-pole device. It integrates a selectable memory function, an integral LED indicator for control status, and a sealable cover that facilitates straightforward settings via screw trimmers.

Notably, the device provides automatic shutdown management and fault information, enhancing quick fault identification and troubleshooting processes. It is suitable for refurbishment projects in existing installations without the necessity of a PLC. The relay's specifications include a maximum measuring cycle of 100 ms and a measurement accuracy of less than 1% across its operational range.

The product is certified according to various standards including IEC 60255-1 and offers protection ratings of IP20 for terminals and IP40 for the housing, ensuring reliable operation in numerous environments.
