Product Description
Isolate a solar PV array locally with the IMO enclosed DC disconnect switch. Choose a one-, two-, three-, or four-string model to maintain separate PV string connections to the inverter&';s MPPT inputs. The product image shows the two-string configuration as an example. Key features 700 V DC UL and cUL rated; 32 A per string. Enclosed IP66 / NEMA 4X construction. True DC isolator to UL 508i, as stated in the supplier datasheet. Arc suppression chamber, self-cleaning knife contacts, and operation-independent switching (3 ms). SAFE-LOCK handle mechanism.

Storage temperature: -50AdegC to 90AdegC (-58AdegF to 194AdegF). Mechanical life: 10,000 operations. Conductor size: 4-16 mm^2, solid or stranded, 12-6 AWG as listed in the datasheet. Terminal tightening torque: 1.7-1.8 NA m. Suitable for localized DC disconnection at ground-mounted arrays or where the inverter is installed away from the array. Select the model for the number of PV strings and verify voltage, current, wiring, enclosure dimensions, and local code requirements before installation. See the supplier&';s IMO DC Disconnect datasheet, version 1.5, for model-specific drawings.
