Bulletin 193-T thermal overload relays are designed for use with Bulletin 100-C contactors and Bulletin 104-C reversing contactors. These class 10 ambient compensated thermal overload relays use integral heater elements; therefore, additional heater elements are not required. Further, the design includes a differential mechanism for sensitivity to single-phase conditions. The trip setting is adjustable over the listed motor full load current range. The overload relay can be operated in a manual or automatic reset mode. An isolated normally open contact is standard. An anti-tamper shield is available and snaps on the front of the overload relay to discourage field adjustments of the trip setting and reset mode.
