PR1
= This device must always be fitted to ensure damages does not occur from inductive loads.
For simple applications PR1 can be replaced by a single TVS, such as 1.5KE220C, across tip
and ring. For applications requiring lightning and mains cross protection further circuitry will be
required and the following protection devices are suggested: P2353AA, P2353AB (Teccor),
THBT20011, THBT20012, THBT200S (SGS-Thomson), TISP72290, TISP7360F3D (T.I.)
BR
= Raychem TR600-150 or equivalent
F1, F2 = Teccor F1250T Slow-Blow Fuse
Protection Components
Figure 4 shows three possible combinations of protection. Depending on the application, the user can select
whether to use a resettable or non-resettable protection scheme.
