IGNITION DESCRIPTION
TRANSFORMERS Ignition transformers series T11 and T16 are suitable for
fluid or gaseous fuel burners.
Ignition transformers series T13 and T17, with 100% duty-
cycle, are particularly suitable for the application on
industrial machines (e.g. water cleaners).
Type T11 and T13

CONSTRUCTION
The magnetic circuit across the transformer is mantle-
shaped (see general features in Figure 1 and Figure 2).
The secondary windings are center grounded.
The transformer is provided with a radio interference
suppression shield, which for its effectiveness must be
connected to a good ground.
Two fire painted caps cover the coils and form a whole with
the magnetic circuit.
Each transformer is detected by the fixed letter T
(transformer), by a series of numbers that indicate the
model and possibly by a letter of the alphabet which
determines a particular fixing system:

screw, 4 mm diameter cylindrical terminal or of a 6.3 mm
diameter cylindrical terminal.
If the fixing system used is standard, the corresponding If not expressly mentioned, the connection terminal used is

For instance, the part reference T11 refers to a transformer
with standard fixing system, whereas the part reference T11/B
corresponds to a T11 transformer with different fixing system INSTALLATION
(see table 1, type B).

features but different fixing systems, or vice versa.
- Respect the applicable national and European standards
(e.g. EN 60355-1 / EN 50165) regarding electrical safety.
OVERALL DIMENSIONS - Make sure that the earth of the transformer and the earth of
the electric system are well connected.
Figures 1 and 2 show the main overall dimensions and Table
1 the various transformers fixing systems. - The device can be mounted in any position.
- Do not put high voltage cables next to other cables.
- Guarantee a protection degree suitable to the application.
