One four-pole auxiliary contact block ( EF22) is supplied standard and is installed on the contactor between T1 and T2. One additional auxiliary contact block can be installed between T2 and T3. Each EF22 contains 2 NO and 2 NC adjustable auxiliary contacts. Standard terminal markings are shown below on the left. If an additional contact block is required, different terminal markings (right) are supplied and may be applied by the user. uxiliary Contacts Main Contacts (open) NC NO Setting range Delayed NO Contact uxiliary Contacts NC NO djusting screw after four turns to the right SSN Main Contacts (open) djustable uxiliary Contacts The instant at which the NO contact closes, in relation to the main contacts, can be adjusted from the front of the EF22 auxiliary contact block by means of an llen wrench.

12 Life Load Curves Life-Load Curves C-3 (90%), C-4 (10%) Contact Life Contact Life for Mixed Utilization Categories C-3 and C-4 In many applications, the utilization category cannot be defined as either purely C-3 or C-4. In those applications, the electrical life of the contactor can be estimated with the following equation: L mixed = L ac3 / [1+P ac4 x (L ac3 /L ac4-1)], where: L mixed pproximate contact life in operations for a mixed C-3/C-4 utilization category application. L ac3 pproximate contact life in operations for a pure C-3 utilization category (from the C-3 life-load curve). L ac4 pproximate contact life in operations for a pure C-4 utilization category (from the C-4 life-load curve).
