Features

• Forced operation contacts (2 Form A 2 Form B, 3 Form A 1 Form B) N.O. and N.C. side contacts are connected through a card so that one interacts with the other in movement. In case of a contact welding, the other keeps a min. 0.5mm .020inch contact gap.
• Independent operation contacts (4 Form A 4 Form B) Each pair of contacts is free from the main armature and is independent from each other. So if a N.O. pair of contacts are welded, the other 3 N.O. contacts are not effected (operate properly) That 53.3±0.3 2.098±.012 25.0 .984 16.5±0.3 .650±.012 53.3±0.3 2.098±.012 33±0.3 1.299±.012 16..
