The ZW-C10T is a thermistor motor protection relay used to protect the motor from overcurrent and overheating. It consists of two parts, the relay and the thermistor, which are connected in series to form a circuit. The thermistor works by sensing the warm air generated during motor operation and the electrical current passing through it. When the temperature or current reading exceed a preset value, the relay will trip, breaking the circuit and preventing further damage to the motor.

The ZW-C10T is most commonly used in industrial applications involving large motors, such as machine tools, pumps and conveyors. It is also suitable for smaller motors, such as those found in HVAC systems and general-purpose controls. The ZW-C10T is also manufactured with an alarm system built-in, as well as a self-test feature to ensure reliable operation.

The working principle of the ZW-C10T is simple. It works by connecting the thermistor and control relay to the motor power line, forming a single unit. When the thermistor senses excess heat or current load, it then triggers the relay, which then shuts off the current to the motor. The ZW-C10T has two modes of operation; delay and lockout. In the delay mode, the thermistor causes the relay to delay its activation for a predetermined amount of time. In the lockout mode, the relay will lock out the motor from any further current when the preset trip level is exceeded.

The ZW-C10T also has an adjustable temperature range, allowing operators to select a range that best suits their application. For example, if the motor is operating in a hot environment, a higher temperature range can be selected to ensure reliable performance. The adjustable range also ensures that any temporary fluctuations in temperature or current load can be managed without triggering the relay.

Overall, the ZW-C10T is an easy to use and reliable motor protection relay. It can be used in a variety of different applications, and is available with a range of features to suit different user requirements. It is an effective way to protect motors from over-current and over-heating, allowing them to run longer and more safely.
