Taking a closer look at the mechanical design characteristics, the 944L is packaged in a low-profile form factor with mounting flanges built into the case. The series is offered in three case heights (40mm, 51mm, and 64mm) all with a diameter of 84.5mm. The terminations are tin-plate brass and are offered in M8 threaded stud or M5 insert options for all case sizes. Both terminal options provide the same high current performance. The plastic case and epoxy fill are flame-retardant to UL94 V-0 standards.
