ST 173 SAFETY starter
DEOS St 173 SAFETY starter for fluorescent lamps in single circuits
 DEOS St 173 SAFETY starter for fluorescent lamps L15W ...32W and
OSRAM DULUX

L 18W and 24W in single circuits for inductive
(> 60,000 switching cycles) and capacitive operation
(> 30,000 switching cycles).
 Reliably disconnects faulty lamps under inductive or capacitive
operating conditions. There is therefore no need to replace a single
faulty lamp instantly. This in turn means longer re-lamping intervals
and greater efficiency.
 Prevents unnecessary power consumption due to short-circuit currents
as DEOS St 172 SAFETY switch-off at the end of lamp life.
 Protects the control gear and luminaire holders.
 With red SAFETY button which can be reset for immediate operation again.
 Service life: DEOS St 173 SAFETY starter approx. 10 years inductive and approx. 5 years
capacitative (for 2 switching operations per day).
 Extension of lamp life by 20%.
Reason: Both lamp electrodes are evenly heated each time the lamp is ignited thanks to the
symmetrical design of the bimetallic strip.
 Self-extinguishing plastic casing made of Makrolon. Class V0
 Equipped with special radio-interference suppression capacitor (foil winding capacitor).
 Suitable for 220V-240V AC operation, 50/60 Hz
 Cannot be used for OSRAM DULUX

S/E, D/E, T/E or T/E IN.
 When the luminaire is used for the first time, push in the red SAFETY button until it clicks.
 Application: For indoor and outdoor lighting, particularly where it is essential for burnt-out
lamps to be reliably shut down.
