PTC Over Current Thermistors
FEATURES
• Transistor protection.
• Motor protection.
• Transformer protection.
• Telecommunication line protection.
PTC Over Current Protectors are used in series to protect
from over current conditions. The PTC will switch from its
normal low resistance to a very high resistance state reducing
the current flow to a safe level. Once this over current
condition has been removed, the PTC will cool to its normal
(low) resistance.
