BH-TB02B-B8D Mini Bimetallic Thermal Protection Switch 250V 2A

mini temperature thermal protector BH-TB02B-B8D bimetallic thermostat rated 250V 2A 30-250C certificated UL TUV CQC KC

1. BH series thermostat’s Principle and structure

BW & BH series that can protect against over-current and over-temperature are sealed firmly, small internal resistance, no noise and reset automatically. When current through bimetal that are sensitive to temperature and current, the status of the bimetal will be changed by over-temperature or over-current to cut off circuit or switch on circuit. BH series are safer than normal protectors, as there is no temperature effect lag under condition of sudden big current.

2. BH series thermostat’s Specification
   1. Electrical Rating:

1. DC-12V max 12A; DC-24V max 10A; AC-125V max 8A; AC-250V max 16A for BH series
2. DC-12V max 4A; DC-24V max 3A; AC-125V max 3A; AC-250V max 2A for BH-TB02 series
   1. Open temperature: (30~150)±5°C; 5°C a step.
   2. Reset temperature: 2/3 of the action temperature with tolerance of ±15°C. Reset temperature can also be provided according to customers' requirement.
   3. Dimension

The thermal protection switch is normally located on the A/C compressor housings. It
is used to prevent compressor damage (overheat) through internal friction.

This switch senses the compressor case temperature and once this case
temperature reaches a predetermined figure the electrical circuit to the compressor
clutch is interrupted.

As the thermal protection switch is connected in series with the compressor clutch
once the compressor case temperature lowers to a predetermined figure the
compressor clutch is then re-energized.
