2. Motor controller - Wikipedia

   en.wikipedia.org/wiki/Motor_controller

   A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...

3. Thermal cutoff - Wikipedia

   en.wikipedia.org/wiki/Thermal_cutoff

   An assortment of thermal fuses. A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).

4. Power system protection - Wikipedia

   en.wikipedia.org/wiki/Power_system_protection

   Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components ...

5. Magnetic starter - Wikipedia

   en.wikipedia.org/wiki/Magnetic_starter

   A magnetic starter has a contactor and an overload relay, which will open the control voltage to the starter coil if it detects an overload on a motor. [1] [2] The overload relay opens a set of contacts that are wired in series with the supply to the contactor feeding the motor. The characteristics of the heaters can be matched to the motor so ...

6. Relay - Wikipedia

   en.wikipedia.org/wiki/Relay

   The thermal and magnetic overload detections are typically used together in a motor protection relay. [citation needed] Electronic overload protection relays measure motor current and can estimate motor winding temperature using a "thermal model" of the motor armature system that can be set to provide more accurate motor protection.

7. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   Fuses and circuit breakers are two commonly used mechanisms for overload protection. [4] A fuse contains a short piece of wire which melts if too much current flows. This effectively disconnects the power supply from its load, and the equipment stops working until the problem that caused the overload is identified and the fuse is replaced.

8. Should you throw out your black plastic cooking utensils? - AOL

   DecaBDE is a type of brominated flame retardant banned by the Environmental Protection Agency (EPA) in 2021. In the study, researchers estimated that using black plastic kitchenware could cause an ...

9. Current limiting - Wikipedia

   en.wikipedia.org/wiki/Current_limiting

   Current limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload. The term "current limiting" is also used to define a type of overcurrent protective device.
