Automotive motor thermal protectors, also known as overload devices or inherent motor protection, are crucial for preventing electric motors from overheating and potentially failing. They detect excessive temperature or current and shut down the motor to prevent damage. These protectors are designed to protect the motor’s internal components, such as windings and insulation, from damage caused by overheating.
To install a motor thermal protector correctly, ensure it’s placed in a location that accurately detects the motor’s temperature, typically near the windings or stator. Proper wiring is crucial, and the protection settings should be adjusted based on the motor’s design and the operating environment.
The Thermostat Switch KSD301 bimetallic disc operates in a Normally Open (NO) configuration. This means the circuit is initially open (disconnected) at normal temperatures. When the temperature rises to a predefined threshold, the bimetallic disc bends, closing the circuit and allowing current flow.
NC type is the “emergency brake” for safety protection, and NO type is the “temperature trigger” for intelligent control. The action logics of the two are complementary. The selection must strictly match the circuit function requirements (comprehensive).
The bimetallic strip is the “temperature sensor + actuator” integrated component of KSD301. Its disc-shaped structure design and alloy ratio directly determine the temperature control accuracy and reliability.
When many customers buy mechanical bimetal disc thermostat & small thermal protection switch, they will find that even if the parameters of bimetallic temperature control switch are the same, the price of different manufacturers is different. What causes the price of bimetal thermostat switch? Today, the editor will give you a detailed explanation of some factors that affect the price of temperature control switch.

A “3MP / 6AP/ 8AM /2AM / 3MP / 17AM+PTC over current & temp bimetallic protector” is a type of electrical safety device that combines a standard ” 3MP ” bimetallic thermal overload protector with a Positive Temperature Coefficient (PTC) thermistor, allowing it to both react to excessive current (overcurrent) and high temperatures, automatically cutting power and resetting once the issue is resolved; essentially acting as a resettable fuse with added temperature protection.
