Overload Relay With Automatic Reset

The ct8 is an economical thermal overload relay that includes standard features like differential tripping automatic manual reset modes and isolated alarm circuit contacts.

Overload relay with automatic reset.

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. Flexible mounting ensures that they can be installed on a contactor panel or separate enclosure. Overload protection ct8 thermal overload relays simple and effective motor protection for applications to 12 amps consistent and reliable protection. With the manual auto reset selection button we can choose between manual and automatic reset of these relays after a trip.

When set in the h or hand position the reset button must be pressed manually to reset the overload relay after a tripping event. Manual or automatic reset and test modes and stop button all in a single device. Manual reset test or auto automatic reset test it is possible to simulate the test and the trip functions by pressing the reset button. Eaton offers a wide range of overload relays to provide full motor protection.

View datasheet thermal overload relays t16 from abb electrification products. Visible trip indication and test function standard on all c3controls series 320 overload relays. The overload relay types include fixed bi metallic interchangeable heater bimetallic and electronic. The overload relay will sense the increased current from the heat and will trip to protect the motor.

An adjustable overload relay could be improperly set up causing it to trip with a normal surge or temporary overload. 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. A reset button is present over the overload relay to reset the overload relay after a trip and clearance of fault.
