ABB IND RT2H Thermal Overload Relay Manual/Auto Reset 54 - 65 A,

C2000 RT overload relays provide motor overload protection through fixed bi-metal heaters. These relays are ambient compensated and utilize a differential mechanism for single-phase sensitivity. The trip setting is adjustable for the range listed. Overload relays may be set for 4 different operational modes—manual reset only, automatic reset only, manual reset/stop, or automatic reset/stop. Stop is initiated by pushing the reset button which interrupts the holding circuit in the latter two listed modes. Overload relays feature visible trip indication, reset on the upstroke, weld check, and trip test.
