Westinghouse Electric PRTAATR Power Relay Module

The Westinghouse PRTAATR Power Relay Module is a circuit-breaker monitoring and remote alarm signaling device designed for use with Westinghouse Digi-trip RMS RS Trip Units. It operates at 120 VAC, 50/60 Hz, and requires 6 VA of control power, fitting as an ATR Power/Relay Module mounted internally in breaker or switchgear assemblies. This module provides remote alarm indication and a relay interface to support breaker status monitoring and signal relay control within switchgear, power distribution panels, and molded case circuit breaker systems, making it compatible with Westinghouse/Cutler-Hammer equipment and suitable for industrial duty environments. Common replacements include the Eaton Digitrip RMS Relay Module, Allen-Bradley Power Monitoring Relay Module, and Schneider Electric Micrologic Relay Module.
