BH-B2D Series Thermostat Principle and Structure
BH-B2D series thermal protectors provide protection against
over-current and over-temperature conditions. They feature a sealed
construction, small internal resistance, no noise generation, and
automatic reset functionality. When current flows through the
temperature and current-sensitive bimetal element, the bimetal
changes state in response to over-temperature or over-current
conditions, either cutting off or switching on the circuit. BH
series protectors are safer than standard protectors, as they
eliminate temperature effect lag under sudden high-current
conditions.

BH-B2D Series Thermostat Application and Instruction
BH series thermal protectors are effective, reliable security
protection and alarm devices widely used in various applications
including 1.5 horsepower motors, lighting devices, inverter welding
machines, switch power supplies, rechargeable battery packs,
fluorescent lamp ballasts, portable power tools, electric
appliances, and other electrical equipment. They prevent damage
caused by over-current and over-heating resulting from abnormal
operating conditions. Enforced types that can withstand pressure of
3.5MPa are suitable for built-in installation in plastic coated
motors.
