Overview

ETC’s Sensor IQ Intelligent Breaker System provides mains-fed power distribution for up to 48 branch circuits in the industry’s most compact footprint. Sensor IQ breakers combine high-inrush rated overcurrent protection, switched power control, and power usage/breaker status reporting in a single device. With built-in station and sensor support via contact input, DMX and Ethernet connectivity, and optional 0–10 V dimming or DALI output, Sensor IQ panels easily integrate into a broad range of systems and applications.
