Overview
The REL52443 is a Schneider Sepam series 20 protection relay in the Easergy range, configured for 3 CT + CSH input and a 12 V DC supply, with 2 RJ45 communication ports and Russian language firmware. It ships in a PCE package and is currently in active production, so lead time is standard for the series.
Selection and comparison
Compared to the REL52441, which runs on a 155.0 V supply, the REL52443 operates at 12.0 V — pick the REL52441 when the control voltage must be 155.0 V rather than 12.0 V. Against the REL52442, which uses an RS485 interface, the REL52443 provides 2 RJ45 ports — choose the REL52442 when RS485 is required over Ethernet.
