Eaton/Moeller ZB65-57 thermal overload relay that is adjustable from 40 to 57 AMPS, has 1 normally open and 1 normally closed auxiliary contact and mounts to the load side any DILM40 through DILM65 3 pole contactor. The ZB65 series of overloads has phase loss protection along with class 10 tripping, which will cut power to the contactor in 10 seconds or less in an over current condition. For a higher AMP range than the ZB65-57, the ZB65-65 offers an adjustable range from 50 to 65 AMPS and mounts to the same frame size contactors.

| Modern motors are built with less metal, which means they dissipate less heat. This calls for the modern protection offered by IEC-style Class 10 overload relays...they trip in 10 seconds under locked rotor conditions. Most motor manufacturers today recommend this type of “close” protection. All Moeller series ZB12 overload relays come with a host of standard features including phase-failure sensitivity, temperature compensation, test / reset buttons and a tripfree release. The auxiliary contacts of the relay disconnect the motor contactor and signal a fault. Moeller series relays can also be used for protecting EExe hazardous location motors. Technical Specifications Class 10 overload; trip response from 2 to 10 seconds Ambient compensated, bimetallic overload tripping mechanism Phase failure sensitive to IEC/EN 60947 Manual / Automatic reset button Built-in NO and NC auxiliary contacts Direct mount to DILM7-10, DILM7-01, DILM9-10, DILM9-01, DILM12-10, DILM12-01 contactors |
