Control Unit for Hubbell Sensors

The CU300A control unit works with Hubbell ATD, ATU, ATP and wall-mount occupancy sensors to manage lighting loads. It operates on 120/277 VAC circuits and includes an internal relay rated at 150 milli-amp. The unit is UL Listed and CSA Certified for compliant installations.

Plenum-Rated Enclosure Changes Placement Options

A plenum-rated housing allows the control unit to be installed in air-handling spaces where standard enclosures are not permitted. The black finish and compact dimensions of 13/8 in. height, 311/16 in. width and 211/32 in. depth help it fit inside junction boxes or above ceiling tiles without violating fire-safety codes.

Verify Sensor Compatibility

Confirm that your existing or planned sensors belong to the Hubbell ATD, ATU, ATP or wall-mount series, as other models will not connect to this control unit. Ensure the supply circuit is either 120 VAC or 277 VAC and that the load does not exceed the 150 milli-amp relay rating. The unit weighs 0.32 lb, so check that the mounting location can support it.
