ST01 Temperature Controlled Switch Bimetallic Thermostat ST01 ST06 Metal Case

BH series thermostat / Miniature thermal protector / Rechargeable battery thermostat

BW & BH series protectors offer protection against over-current and over-temperature conditions. They feature sealed construction, small internal resistance, no noise, and automatic reset functionality. When current flows through the temperature and current-sensitive bimetal, the bimetal's status changes in response to over-temperature or over-current conditions, either cutting off or switching on the circuit. BH series provide enhanced safety compared to standard protectors, with no temperature effect lag under sudden high current conditions.

BH series thermal protectors are effective, reliable security protector and alarm devices widely used in:

• 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

These protectors prevent damage from over-current and over-heating caused by abnormal operating conditions. Enforced types capable of withstanding 3.5MPa pressure are suitable for built-in installation in plastic coated motors.

H20/H21 series universal and enhanced protectors feature large metal casings and are composed of thermal conductive metal casing, bimetallic parts welded with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat resistance cables. During abnormal operation, when environmental temperature increases to the set value, the bimetallic parts perform quick action, opening the contact points and disconnecting the circuit. When the device cools to safe operating temperature, the contact points automatically close and normal operation resumes.

H20/H21 series is applicable to rechargeable batteries, ballasts, massagers, micro motors, transformers, electric tools, heating electric appliances, and instruments.
