SF3 - POLARISED / MONOSTABLE SAFETY RELAY with (mechanical linked) forced contacts operation

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 (o.

SF POLARISED, MONOSTABLE SAFETY RELAY with (mechanical linked) forced contacts operation π 53.3±0.3 2.098±.012 25.0 .984 16.5±0.3 .650±.012 (SF3 pending) (SF3 pending) (SF3 pending) SF-RELAYS 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 (UL/CSA, SEV of SF3 pending) FEATURES • Forced operation contacts (2 Form A 2 Form B, 3 Form A 1 Form B) N.O. and N.C.
