Description:
BK05-BB1D series THERMAL PROTECTOR is a precise protector with small size. It is sensitive, accurate and reliable, especially suitable for heat cable, battery protection board, micro-motor and security protection of transformer. BK05-BB1D series THERMAL PROTECTOR is using a special shape of double metal piece without auxiliary mechanism. The status of metal piece has the fast change is only depended on the self temperature sensing of the metal piece and the current thermal reaction. It makes the contact realize the cut off the power automatically and get through the power. The over heating protection and overload protection will be raised.
Work Principle:
BK05 type bimetal thermal protector is using the double metal piece
as e temperature sensing element. When the electrics work normally,
the double piece is at the free status, the contact is at
close/break off position. When the temperature rises to the action
temperature, the double metal piece acts fast by the inside force
caused by heating, open/close the contact, cut off/get through the
power, the temperature protection function is raised. When the
temperature lows to the reset temperature, the contact
closes/breaks off automatically and recovery to normal work status.
Applications:
Battery pack, Li battery protect board
Electrical tools
PC board, temperature sensitive cable
Heating-pads, electrical blankets
Fluorescent ballasts and lightings, transformers
Competitive Advantages:
Small size, Installation is more flexible and convenient;
Have the stable work characteristics and excellent reliability;
Sensitive temperature and snap action;
Nickel and wires are optional;
Each type of parts strictly implemented European ROHS environmental standards;
Terminals are optional with normally closed Model B and normally open Model K
