SF-RELAYS

• 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 enables to plan a circuit to detect welding or go back to the beginning condition.
• Separated chamber structure (2 Form A 2 Form B, 3 Form A 1 Form B,4 Form A 4 Form B)
   N.O. and N.C. side contacts are put in each own space surrounded with a card and a body-separater. That prevents
short circuit between contacts, which is caused by their springs welding or damaged.
• UL/CSA, TÜV, SEV approved
