Product Description
ETC AR20 Dual 20A 5.5KW Relay Module - 277V
General Informat i o n
The Relay Module is a dual, plug-in mechanical relay assembly for use in the Unison Dimming Series rack enclosures. Each Relay Module provides two electrically held relays, in the same form factor as standard dimmer modules. This enables designers to mix and match dimmer and relays for control of diverse loads. Ideal for control of non-dimmable load types such as HID lamps.
APPLICATIONS • Designed for use in Unison 277V Unison DRd rack enclosures • High Intensity Discharge ballasts (Metal Halide and High Pressure Sodium) • Non-dimmed On/Off loads • Motors • Power for fans and standard outlets • Moving lights, fog machines and other powered effects
FEATURES • Level-activated mechanical relays • Two circuits per module • High-density modular assembly • Die-cast aluminum chassis • Fully magnetic circuit breakers
GENERAL • 65,000A Short Circuit Current Rating (SCCR) • UL and cUL LISTED
