AC power: general

Warning!

It is the installer’s responsibility to ensure that all local safety 
regulations and legal requirements are observed when 
installing and connecting the Rail Light, and that all power 
cable and equipment is adequately dimensioned and of 
appropriate type for the installation.

It is the installer’s responsibility to calculate the power and current 
requirements of the installation and make sure that cables and equipment 
are adequately dimensioned. Power voltage, current, wattage and power 
factor data are given in the Specifications section on page 22.

Inrush currents and electronic circuit-breakers

If luminaires are switched on at the AC power voltage peak, their electronic 
control gear systems cause a large but very brief current surge. The 
OSRAM electronic QTi ballasts in Rail Light luminaires draw an inrush 
current of max. 28 amps for max 220 microseconds when power is applied. 
Table 1 gives full data and the maximum number of armatures per 10 A 
automatic circuit breaker recommended by OSRAM.

In connection with Table 1 please note the following:

• The data is per armature. Since Rail Light luminaires can contain one or 

more armatures you must calculate accordingly.

• The recommended maximum applies to N circuit breakers of Type 5 SN1–

6 and 5 SX with B characteristics. If circuit breaker types with C 
characteristics are used, the number of armatures can be doubled (but 
where applicable, bear in mind DIN standard VDE 0100 Part 410).

• Table 1 gives data for single-pole circuit breakers. When multi-pole circuit 

breakers are employed (2-pole, 3-pole) the maximum number of 
armatures is reduced by 20%.

• The recommended maximum is for a line impedance of 800 m

Ω

. This 

corresponds to a 15 m, 1.5 mm² (49 ft., 16 AWG) cable from the
