2 October 008 DC Contactors Type C8 Ltl Inductive Time Limit Cat. No. 6006H0 Size dc Ltl Contactor Product Description DC Inductive Time Limit (Ltl) Contactors are mill type contactors used for acceleration and plugging functions. The contactor uses two coils; one a normal closing coil, and the other a holdout coil. When the closing coil is energized, the contactor will not pick up until the magnetism of the holdout coil has decayed sufficiently to permit the contactor to close. By connection of the holdout coil (H.O.) to various points in control circuits, the Ltl contactor can be used to control acceleration or plugging in hoist and travel panels. The construction of the arc chute, blowout and power contacts of these contactors is the same as for C80 DC contactors. Contact tips, closing coils, arc chute assemblies, and interlocks are interchangeable between the two types of contactors. Refer to Page for a description of these features. Course adjustment of the timing is accomplished by removing shims to vary the air gap of the holdout coil circuit. Fine adjustment is made with a knurled nut at the base of the holdout coil magnet core. Standards and Certifications NEMA ICS44, 44, 44. NEMA ICS.. NEMA ICS NEMA ICS..0.
