AtlasIED HLE-series explosion-proof drivers are UL listed for Class I, Division 1 Groups B, C and D environments, extending suitability to hydrogen-containing hazardous atmospheres in addition to common Group C/D gases. Models include low-impedance and 70.7V transformer-equipped versions.
Match the exact hazardous classification, power, impedance/transformer requirement and compatible HLE/MLE-30 or HLE/MLE-32 horn projector. Installation must follow the listed method and applicable electrical code for hazardous locations.
The B-group rating is a critical distinction; it should not be substituted with a C/D-only driver in a Group B location.
Match the exact hazardous classification, power, impedance/transformer requirement and compatible HLE/MLE-30 or HLE/MLE-32 horn projector. Installation must follow the listed method and applicable electrical code for hazardous locations. Representative Wallco listings include WAL07-HLE-3, WAL07-HLE-3T, WAL07-MLE-3.
The B-group rating is a critical distinction; it should not be substituted with a C/D-only driver in a Group B location.
Confirm speaker type, coverage, driver size, transformer voltage/taps or impedance, mounting hardware, environmental exposure and any safety/plenum listing.
Yes. Provide the existing AtlasIED part number when replacing equipment, or send the system voltage/impedance, application, mounting location and project requirements for new designs.
