Product details

Overview

The RUMC3GB2BD is a Harmony RUM plug-in relay with 3 C/O contacts rated for 3 A switching current, a maximum switching capacity of 750 VA AC or 84 W DC, and a minimum of 15 mW — covering both power loads and low-level signals. Its 24 V DC coil draws 1.4 W at 470 Ω, and the relay carries UL, CSA, and IEC 61810-1 certifications for panel acceptance.

Selection vs RUMC3AB2E7

Compared to the RUMC3AB2E7, which switches 10 A at 750 VA AC / 84 W DC with a 15 mW minimum, the RUMC3GB2BD is the lower-current, lower-power sibling — its 3 A / 750 VA AC / 84 W DC rating suits signal-level and light control loads, while the RUMC3AB2E7 handles heavier contactor or motor-starter duty.
