Product details

Overview

The RUMC2AB2B7 is a Schneider Harmony Relay plug-in relay with a 24 V DC coil (72 ohm resistance) and 2 C/O contacts rated for 10 A switching current. Its maximum switching capacity is 2500 VA AC or 280 W DC, with a minimum of 170 mW, covering both power and low-level signal loads. It carries UL 508, EN/IEC 61810-1, and CSA C22.2 No 14 certifications, with a lockable test button and status LED for panel troubleshooting.

Compared to the RXM2AB1E7, the RUMC2AB2B7 has a lower maximum switching capacity (2500 VA) and a lower switching current (10 A).
