STR2-D33 Thermal Overload Relay

STR2-D33 Thermal overload relays work on the principle of the thermal effect of electric current. When a motor is overloaded, its current increases, causing the heating element inside the thermal overload relay to heat up. This heat is transferred to the bimetal, which is made of two metals with different coefficients of thermal expansion, so it bends when heated. When the bending reaches a certain point, it triggers a mechanical device, usually a contact, which disconnects the power supply to the motor, thus protecting it from damage.

Electronics Contactor

SONTUOEC high quality electronics contactor is mainly applied in the circuits the rated voltage up to 660V, AC 50Hz or 60Hz, rated current up to 95A, for making & breaking, frequently starting & controlling the AC motor. Combined with the auxiliary contact block, timer delay & machine-interlocking device etc, it becomes the delay contactor, mechanical interlocking contactor, star-delta starter. It turns into an electromagnetic starter when it works together with a matching Thermal Relay, which can protect the overload circuit. The Contactor is produced according to IEC60947-4-1.

3 Pole AC Contactor

3 Pole AC Contactor is an AC contactor with three independent contacts (or poles), each of which controls one phase of a three-phase power system. Its main function is to remotely control the starting, stopping and reversing of three-phase motors or other three-phase loads. By controlling the on and off of these three contacts, it can realize the connection and disconnection of the three-phase circuit, thus controlling the working status of the electric load.
