Custom AC Bimental Magnetic Overcurrent Relays Current Range 0.1 - 22A 3P Standard Type

UKH-22/3 OEM /ODM acceptable Custom AC Bimental Magnetic Thermal Overload Relay Current range 0.1~22A 3P Standard type General: 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

Custom AC Bimental Magnetic Thermal Overload Contactor Relay GTH-85

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

quality Safety Phase Failure Protection Industrial Relays , Easy Operation factory

Safety Phase Failure Protection Industrial Relays , Easy Operation

Safety Phase Failure Protection Industrial Relays , Easy Operation 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.
