Bulletin 193-T — Bimetallic Overload Relays


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.

¬ Bulletin 193-T overload relays should not be direct mounted with DC coil contactors.
T To select the setting range for use in Y-D Starters, multiply the rated operating current of the motor by a factor of 0.58.
‡ For motors with service factor of 1.15 or greater, use motor nameplate full load current. For motors with service factor of 1.0, use 90% of the motor nameplate full load current.

Trip Characteristics

These trip characteristics refer to IEC 60947 and are average values from cold start at an ambient temperature of 20 °C. Trip time is pictured as a function of operating current. With the device at normal operating temperature, the trip time decreases to approximately 25% of the shown value.
