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
gap.

SF RELAYS
• Separated chamber structure
(2 Form A 2 Form B, 3 Form A
1 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
