Product details

Overview

The REL21301 is a Schneider MiCOM P123 autoreclose relay rated for 1 A current, with 4 current inputs (CT X/5 A and X/1 A) and 5 discrete inputs, plus 9 discrete outputs. It supports Modbus RTU, IEC 60870-5-103, and DNP3 protocols, and is flush-mounted with a 250 V DC supply.

Lifecycle and sourcing

Schneider lists the REL21301 as discontinued. For existing installations needing this exact code, sourcing is through surplus and broker channels; an RFQ confirms available quantity and lead time.
