The ZKHPN1142B10 is a solid-state thermal overload relay designed for the protection of motors and other loads from damage resulting from overloading. The ZKHPN1142B10 is used to control and protect an electric motor from damage due to overloads and short-circuits. The unit also provides alarms for on/off status and faults that occur during motor operation.

Application field

The ZKHPN1142B10 is designed for use in industrial applications with thermal overload relays. It can be used to protect electric motors, including single-phase, three-phase, cage and fractional-horsepower motors. The unit can be used in either AC or DC applications.

Working Principle

The ZKHPN1142B10 is designed to protect motors from overloads and short-circuits. It has a built-in thermal overload relay that is designed to detect changes in the temperature of the motor due to an overload. If an overload is detected, the relay will trip, shutting the motor off and protecting it from further damage. The relay can also detect short-circuits, and will trip if a short-circuit occurs.

The unit is also equipped with an electronic circuit which detects the on/off state of the motor, and can provide alarm signals for both when the motor is powered on and off. The unit also provides fault diagnostics for irregularities which may occur during the operation of the motor, such as overvoltages, undervoltages, voltage imbalances, and overloads. The unit also has a reset switch, which allows the user to manually reset the thermal relay in the event of a fault.

The ZKHPN1142B10 is a user-friendly and reliable device that can provide reliable motor protection for a variety of industrial applications. It is easy to install and can be mounted directly onto the motor or mounted on a DIN rail for a more permanent solution. The unit is UL Listed and CSA Certified for safety.
