It operates at 240V with a 65kA interrupting capacity at that voltage, supporting 1-phase systems via a feed-thru connection. The JD frame unit weighs 20 lb and features a bolt-on mounting style with fixed line lugs for secure installation. It is UL and IEC certified, compliant with RoHS standards, and rated for ambient temperatures from -13°F to 158°F (-25°C to 70°C).
