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

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)
