FAQs

For Class I, Division 1 installations, begin by confirming the enclosure rating and area classification, then mount the single-gang housing with the 1" hub. Route and connect the two pushbuttons to the control circuit, wire 120-277V at up to 20A, and secure the device per the IF 328 guidelines to ensure compliance and safe operation.
The EDS3129 GB is rated for 20A at 120-277V, with a single-pole configuration and two pushbuttons in a 1" hub, single-gang footprint. This supports compact panel layouts, reduces external components, and simplifies wiring diagrams for hazardous-location control stations in automation panels.
Yes. The unit features a 1" hub and is specified as a single-gang, single-pole device with a switch, designed for Hazardous/Classified Locations. This configuration streamlines installation and supports integration with other 1" hub accessories while meeting NEC/CEC requirements.
The EDS3129 GB carries NEC/CEC compliance and hazardous location ratings including Class I Division 1, Group B, along with NEMA ratings 3, 7, and 9. These certifications mean the control station meets stringent electrical safety and enclosure durability requirements for oil, gas, mining, and chemical environments.
By combining a rugged Feraloy enclosure, a compact footprint, and NEC/CEC compliance for hazardous locations, the unit reduces maintenance cycles, minimizes field wiring complexity, and lowers risk during audits. Its durable construction and available installation guides support faster commissioning and a favorable total cost of ownership.
