overload protection relay

GTH40 UL Magnetic Thermal Overload Relay Electrical Protective Relays UKH series thermal overload relays apply to circuit of AC 50Hz or 60Hz, rated voltage to below 660V and rated current . 1A-800A for AC motor overload and open-phase protection during long time or intermittent long time service, which can also protect 3-phase serious imbalance and long starting time of motor or long timer operation, can also be used for corresponding AC contactor for electromagnetic starter.

Class 10A Manual / Automatic Overload Thermal Relay With AC Contactor Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a normally closed (NC) relay. When excessive current flows through the motor circuit, the relay opens due to increased motor temperature, relay temperature, or sensed overload current, depending on the relay

Custom AC Bimental Magnetic Thermal Overload Contactor Relay GTH-85 Bimetallic thermal overload relays use a bimetallic strip to mechanically open the contacts. Bimetallic strips consist of two conjoined pieces of metal which expand at different rates when exposed to heat. This difference forces the strip to bend when heated. In a thermal relay, the strip is attached by a spring to a contact. When excess heat from overcurrent causes the strip to bend and pull the spring, the

GTH-12M Mini Motor Thermal Overload Relay , Overload Protection Relay Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a normally closed (NC) relay. When excessive current flows through the motor circuit, the relay opens due to increased motor temperature, relay temperature, or sensed overload current, depending on the relay

Bimetallic thermal overload relay 9A,12A, 18A, 22A for motor protection Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a normally closed (NC) relay. When excessive current flows through the motor circuit, the relay opens due to increased motor temperature, relay temperature, or sensed overload current, depending on the relay

AC 3 Phase ls Thermal Overload Relay , 100A 125A Contactor Relay Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a normally closed (NC) relay. When excessive current flows through the motor circuit, the relay opens due to increased motor temperature, relay temperature, or sensed overload current, depending on the relay type.
