High-Performance 277V Relay Module for Dimming Racks

The ETC AR20 is a robust, dual 20-amp, 277V relay module engineered for seamless integration with Unison Dimming Series rack enclosures. Ideal for controlling non-dimmed loads such as motors, fans, moving lights, and HID ballasts, it ensures consistent performance in demanding applications. Its magnetic circuit breakers and high inrush tolerance make it especially reliable for high-load switching environments.

ETC AR20 Competitive Differences

Dual 20A mechanical relays with level activation for reliable on/off switching
Rated for 200,000 full-load activations and 5 million no-load activations
High-density modular design with plug-in assemblies for easy installation
Fully magnetic circuit breakers with 20x inrush current tolerance
65,000A SCCR with hot-patching capabilities
UL and cUL Listed for continuous duty at 100% rated load (5.5kW)

ETC AR20 Description

The ETC AR20 is specifically designed to support non-dimmed, switched loads within Unison 277V DRd rack systems. With its dual 20A mechanical relays and die-cast aluminum chassis, it delivers durability, efficiency, and optimal thermal performance via an integrated bonded heatsink. Perfect for powering motors, HID ballasts (metal halide, high pressure sodium), fog machines, moving lights, and other high-draw effects, this module is an essential component for venues demanding reliable power distribution and switching control. Engineered for high-frequency use, it maintains a high inrush rating and extended relay life, making it suitable for commercial and entertainment applications alike.
