Specifications:
. 673635.003
Designed for use as internally mounded
built-in components in
-circuits 50 Hz or
60 Hz, including single-phase
asynchronous motors, three-phase
asynchronous motors, for power supply
from single-phase electric lines and also
for
se in fluorescent lamps and other
discharge lamps.
Can be used instead of
, 75-10.
Design: designs " ", " ", " ", " ", " ", " " are
wrapped with adhesive tape; capacitor ends
sealed with epoxy compound (with joining pin
for design " ").
Designs " " and " " are in plastic case.
Designs " " and " " are for D 25mm, design
