Overload Relay With Automatic Reset

Manual reset test or auto automatic reset test it is possible to simulate the test and the trip functions by pressing the reset button.

Overload relay with automatic reset.

The sensing device of a bimetal strip made of two metals. View datasheet thermal overload relays t16 from abb electrification products. Overload protection ct8 thermal overload relays simple and effective motor protection for applications to 12 amps consistent and reliable protection. If the.

Manual or automatic reset and test modes and stop button all in a single device. Offer reliable protection for motors in the event of overload or phase failure. Flexible mounting ensures that they can be installed on a contactor panel or separate enclosure. A reset button is present over the overload relay to reset the overload relay after a trip and clearance of fault.

The t16 thermal overload relays are economic electromechanical protection devices for the main circuit. The motor will stop if the overload relay trips out and will not restart automatically regardless of the position of any control switch until the overload relay is reset. Visible trip indication and test function standard on all c3controls series 320 overload relays. With the manual auto reset selection button we can choose between manual and automatic reset of these relays after a trip.

Also the overload relay itself could fail. When set in the h or hand position the reset button must be pressed manually to reset the overload relay after a tripping event. Automatic reset thermal overload relays. The ct8 is an economical thermal overload relay that includes standard features like differential tripping automatic manual reset modes and isolated alarm circuit contacts.

In the case of motors that are automatically controlled the overload relay may be set to hand or auto reset as the situation requires. Eaton offers a wide range of overload relays to provide full motor protection. Thermal trip class 10 overload protection trips within 10 seconds when carrying a current of 720. On the overload relays that i was looking at it has a reset button that must be manually reset but the motor will start immediately when the reset is pressed is this automatically starting not acceptable unless the monitor the extra auxiliary contact is used to stop the motor control relay contactor by control the relay or monitoring.

If the device is set to auto a remote reset of olr is possible. The overload relay will sense the increased current from the heat and will trip to protect the motor.
