8AM Bimetal Thermal Protector & Motor Overload Protector

An ” HC18 / 8AM motor bimetal thermal protector” refers to a specific type of thermal overload protector, typically manufactured by China YAXUN , designed to protect an oil pump motor from overheating by automatically cutting off power to the motor when its temperature reaches a critical level; de “8AM” designation signifies a particular model within YAXUN’s line of motor thermal protectors, often used in applications like automotive oil pumps, motor, submersible pumps, high-pressure cleaners, oil pump motors, large wiper motors, tvättmaskiner, dammsugare, ballaster, transformers due to their compact size and fast response time.

Key points about an 8AM oil pump motor thermal protector:
Fungera:
HC18 / 8AM series bimetall protector is an overheat protection element that has both overtemperature protection and precise control of current overload. It can effectively prevent Damage caused by excessive current and high temperature to high-power motors, transformatorer, etc.

[Temperature]: 80℃-180℃

[Funktioner]: Large electrical capacity, long life and high reliability; Very precise tripping time to prevent motor overheating; has dual functions of induction current and temperature
When the motor gets too hot, the thermal protector’s internal bimetallic disc bends, breaking the electrical circuit and temporarily stopping the motor to prevent damage from excessive heat.

Benefits:
Overheat protection: Prevents motor burnout by automatically tripping when temperature exceeds a preset limit.
Reliable reset: Most 8AM protectors are manually resettable, allowing the motor to restart once the temperature cools down.
Compact size: Suitable for tight spaces within an oil pump motor assembly.
